Selenium Questions Part4: User Actions and Selenium Scripts

1. How do I launch the browser using WebDriver?
Answer:  
Launching Firefox Browser
Firefox is one of the most widely used browsers in automation. The following steps are required to launch the firefox browser.
1.Download geckodriver.exe from GeckoDriver Github Release Page. Make sure to download the right driver file based on your platform and OS version.
2.Set the System Property for “webdriver.gecko.driver” with the geckodriver.exe path – System.setProperty(“webdriver.gecko.driver”,”geckodriver.exe path”);
public class FirefoxBrowserLaunchDemo {

    public static void main(String[] args) {

        //Creating a driver object referencing WebDriver interface

        WebDriver driver;

        //Setting webdriver.gecko.driver property

        System.setProperty("webdriver.gecko.driver", pathToGeckoDriver + "\\geckodriver.exe");

        //Instantiating driver object and launching browser

        driver = new FirefoxDriver();

        //Using get() method to open a webpage

        driver.get("http://automationtestinginsider.com");

        //Closing the browser

        driver.quit();

    }

}

Launching Chrome Browser
1.Download the latest ChromeDriver binary from Chromium.org download page and place the executable on your local machine.
2.Set the webdriver.chrome.driver property to the chromeDriver.exe’s location as-
System.setProperty(“webdriver.chrome.driver”, “chromeDriver.exe path”);
public class ChromeBrowserLaunchDemo {

    public static void main(String[] args) {

        //Creating a driver object referencing WebDriver interface

        WebDriver driver;

        //Setting the webdriver.chrome.driver property to its executable's location

        System.setProperty("webdriver.chrome.driver", "/lib/chromeDriver/chromedriver.exe");

        //Instantiating driver object

        driver = new ChromeDriver();

        //Using get() method to open a webpage

        driver.get("http://automationtestinginsider.com");

        //Closing the browser

        driver.quit();

    }

}

Launching Internet Explorer Browser
Like ChromeDriver, InternetExplorer driver also requires setting up the “webdriver.ie.driver” property with the location of IEDriverServer.exe. The IEDriverServer.exe can be downloaded from here.
public class IEBrowserLaunchDemo {

    public static void main(String[] args) { 

        //Creating a driver object referencing WebDriver interface

        WebDriver driver;

        //Setting the webdriver.ie.driver property to its executable's location

        System.setProperty("webdriver.ie.driver", "/lib/IEDriverServer/IEDriverServer.exe");

        //Instantiating driver object

        driver = new InternetExplorerDriver();

        //Using get() method to open a webpage

        driver.get("http://automationtestinginsider.com");

        //Closing the browser

        driver.quit();

    }

}

2.  How do you use findElement() and findElements()? 

Answer:  findElement(): findElement() is used to find the first element in the current web page matching to the specified locator value. Take a note that only first matching element would be fetched.
Syntax:
WebElement element = driver.findElements(By.xpath(“//div[@id=’example’]//ul//li”));

findElements(): findElements() is used to find all the elements in the current web page matching to the specified locator value. Take a note that all the matching elements would be fetched and stored in the list of WebElements.
Syntax:
List <WebElement> elementList = driver.findElements(By.xpath(“//div[@id=’example’]//ul//li”));

3. How can you find whether an element is displayed on the screen using Selenium?

Answer:  WebDriver facilitates the user with the following methods to check the visibility of the web elements. These web elements can be buttons, drop boxes, checkboxes, radio buttons, labels etc.
isDisplayed()
isSelected()
isEnabled()

4. How can we get a text on a web element using Selenium?

Answer:  Get command is used to retrieve the inner text of the specified web element. The command doesn’t require any parameter but returns a string value. It is also one of the extensively used commands for verification of messages, labels, errors etc displayed on the web pages.
Using getText() method.
String  eleText= driver.findElement(By.xpath(“ ”)).getText();

5. How to type into a text box using Selenium?

Answer:  User can use sendKeys(“String to be entered”) to enter the string in the textbox.
WebElement username= driver.findElement(By.id("uname"));
username.sendKeys("testusername");

6. How to select a check box in Selenium?

Answer:  WebElement option1 = driver.findElement(By.id("checkbox123"));                                     
// This will Toggle the Check box                              
option1.click();

7. How to press enter key in selenium

Answer:  driver.findElement(By.id("Value")).sendKeys(Keys.ENTER);

8. How to enter input in textbox without using sendkeys

Answer:  You can use Javascript Executer to input text into a text box without using sendKeys() method:
// Initialize JS object
JavascriptExecutor JS = (JavascriptExecutor)webdriver;
// Enter username
JS.executeScript("document.getElementById('User').value='admin'");
// Enter password
JS.executeScript("document.getElementById('Password').value='password123'");

9. How to get no of frame present

Answer:  
//First finding the elements using any of locator strategy
 List<WebElement> iframList = driver.findElements(By.tagName("iframe"));
  int totalFrames = iframList.size();
  System.out.println("No of Frames:" + totalFrames);

10. How to handle new tab?

Answer:  Please refer below article on how to handle multiple windows/tabs

11. What are the three ways to initialize webdriver?

Answer: Answer will be provided soon.

12. How to select all the check boxes in a page?

Answer: Below is the sample script given:

List<WebElement> list = driver.findElements(By.Xpath("//input[type='checkbox']"));
for(WebElement el : list){
    if(!el.isSelected()) // validate Checked property, otherwise you'll uncheck!
        el.click();
}

13. How to verify whether the checkbox option or radio button is selected or not?

Answer: Below is the sample script given:

String str = driver.findElement(By.id("26110162")).getAttribute("checked");
if (str.equalsIgnoreCase("true"))
{
    System.out.println("Checkbox selected");
}

14. What is the alternative way to click on login button?

Answer: use submit() method but it can be used only when attribute type=submit.

15. How to handle a drop-down field and select a value from it using Selenium?

Answer: Value in the drop down can be selected using WebDriver’s Select class.
Syntax:
selectByValue:
Select selectByValue = new Select(driver.findElement(By.id(“SelectID_One”)));
selectByValue.selectByValue(“greenvalue”);
selectByVisibleText:
Select selectByVisibleText = new Select (driver.findElement(By.id(“SelectID_Two”)));
selectByVisibleText.selectByVisibleText(“Lime”);
selectByIndex:
Select selectByIndex = new Select(driver.findElement(By.id(“SelectID_Three”)));
selectByIndex.selectByIndex(2);

16. How to check which option in the drop-down is selected?

Answer:  You should be able to get the text using getText() (for the option element you got using getFirstSelectedOption()
Select select = new Select(driver.findElement(By.xpath("//select")));
WebElement option = select.getFirstSelectedOption();
String defaultItem = option.getText();
System.out.println(defaultItem );

17. How to select a third value from a drop-down field?

Answer:  

Sample HTML
<html>
<body>
<select id = "designation">
<option value = "MD">MD</option>
<option value = "prog"> Programmer </option>
<option value = "CEO"> Chief Executive Officer </option>
</option>
</select>
<body>
</html>

Now to identify dropdown do
Select dropdown = new Select(driver.findElement(By.id("designation")));
To select its option say 'CEO' you can do
dropdown.selectByVisibleText("CEO");
or
dropdown.selectByIndex(2);
or
dropdown.selectByValue("CEO");

18. How to find more than one web element in to a list?

Answer: At times, we may come across elements of same type like multiple hyperlinks, images etc arranged in an ordered or unordered list. Thus, it makes absolute sense to deal with such elements by a single piece of code and this can be done using WebElement List.
Sample Code
// Storing the list
List <WebElement> elementList = driver.findElements(By.xpath("//div[@id='example']//ul//li"));
// Fetching the size of the list
int listSize = elementList.size();
for (int i=0; i<listSize; i++)
{
// Clicking on each service provider link
serviceProviderLinks.get(i).click();
// Navigating back to the previous page that stores link to service providers
driver.navigate().back();
}

19. How to handle frames in WebDriver?

Answer:  An inline frame acronym as iframe is used to insert another document with in the current HTML document or simply a web page into a web page by enabling nesting.
Select iframe by id
driver.switchTo().frame(“ID of the frame“);
Locating iframe using tagName
driver.switchTo().frame(driver.findElements(By.tagName(“iframe”).get(0));
Locating iframe using index
frame(index)
Example:
driver.switchTo().frame(0);
frame(Name of Frame)
driver.switchTo().frame(“name of the frame”);
frame(WebElement element)
Select Parent Window
driver.switchTo().defaultContent();
Please refer below link to get more details on iframe in selenium

20. How to click on a hyperlink using Selenium WebDriver?

Answer:  driver.findElement(By.linkText(“Google”)).click();
The command finds the element using link text and then click on that element and thus the user would be re-directed to the corresponding page.
The above mentioned link can also be accessed by using the following command.
driver.findElement(By.partialLinkText(“Goo”)).click();
The above command find the element based on the substring of the link provided in the parenthesis and thus partialLinkText() finds the web element with the specified substring and then clicks on it.

21. How to read and verify the text on the tooltip using Selenium WebDriver?

Answer:  please refer below link

22. How to execute JavaScript in Selenium?

Answer:  JavaScriptExecutor is an interface which provides mechanism to execute Javascript through selenium driver. It provides “executescript” & “executeAsyncScript” methods, to run JavaScript in the context of the currently selected frame or window
JavascriptExecutor js = (JavascriptExecutor) driver; 
js.executeScript(Script,Arguments);

23. How can we handle window based pop up using Selenium?

Answer:  Selenium is an automation testing tool which supports only web application testing. Therefore, windows pop up cannot be handled using Selenium.
But we can handle it using third party tool like AutoIT. Please refer below link.

24. How can we handle web-based pop up using Selenium?

Answer:  WebDriver offers the users with a very efficient way to handle these pop ups using Alert interface. There are the four methods that we would be using along with the Alert interface.
 void dismiss() – The accept() method clicks on the “Cancel” button as soon as the pop up window appears.
 void accept() – The accept() method clicks on the “Ok” button as soon as the pop up window appears.
 String getText() – The getText() method returns the text displayed on the alert box.
 void sendKeys(String stringToSend) – The sendKeys() method enters the specified string pattern into the alert box.
Syntax:
// accepting javascript alert
                Alert alert = driver.switchTo().alert();
alert.accept();
Please refer below link to get more details on popups in selenium

25. How to assert title of the web page?

Answer: //verify the title of the web page
assertTrue(“The title of the window is incorrect.”,driver.getTitle().equals(“Title of the page”));

26. How to mouse hover on a web element using WebDriver?

Answer:  WebDriver offers a wide range of interaction utilities that the user can exploit to automate mouse and keyboard events. Action Interface is one such utility which simulates the single user interactions.
Thus, In the following scenario, we have used Action Interface to mouse hover on a drop down which then opens a list of options.
Sample Code:
// Instantiating Action Interface
Actions actions=new Actions(driver);
// howering on the dropdown
actions.moveToElement(driver.findElement(By.id("id of the dropdown"))).perform();
// Clicking on one of the items in the list options
WebElement subLinkOption=driver.findElement(By.id("id of the sub link"));
subLinkOption.click();

37. How can you find broken links in a page using Selenium WebDriver?

Answer: One of the key test case is to find broken links on a webpage. Due to existence of broken links, your website reputation gets damaged and there will be a negative impact on your business. It’s mandatory to find and fix all the broken links before release. If a link is not working, we face a message as 404 Page Not Found.
Let’s see some of the HTTP status codes.
200 – Valid Link
404 – Link not found
400 – Bad request
401 – Unauthorized
500 – Internal Error
Consider a test case to test all the links in the home page of “automationtestinginsider.com”
Below code fetches all the links of a given website (i.e., utomationtestinginsider.com) using WebDriver commands and reads the status of each href link with the help of HttpURLConnection class.

System.out.println("My Site Title: " + sitetitle);

45. How to handle Ajax calls in Selenium WebDriver?

Answer:  Handling AJAX calls is one of the common issues when using Selenium WebDriver. We wouldn’t know when the AJAX call would get completed and the page has been updated. In this post, we see how to handle AJAX calls using Selenium.
AJAX stands for Asynchronous JavaScript and XML. AJAX allows the web page to retrieve small amounts of data from the server without reloading the entire page. AJAX sends HTTP requests from the client to server and then process the server’s response without reloading the entire page. To handle AJAX controls, wait commands may not work. It’s just because the actual page is not going to refresh.
When you click on a submit button, required information may appear on the web page without refreshing the browser. Sometimes it may load in a second and sometimes it may take longer. We have no control on loading time. The best approach to handle this kind of situations in selenium is to use dynamic waits (i.e. WebDriverWait in combination with ExpectedCondition)

titleIs() – The expected condition waits for a page with a specific title.
wait.until(ExpectedConditions.titleIs(“Deal of the Day”));
wait.until(ExpectedConditions.titleIs(“Deal of the Day”));
elementToBeClickable() – The expected condition waits for an element to be clickable i.e. it should be present/displayed/visible on the screen as well as enabled.
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("xpath")));
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("xpath")));
alertIsPresent() – The expected condition waits for an alert box to appear.
wait.until(ExpectedConditions.alertIsPresent()) !=null);
wait.until(ExpectedConditions.alertIsPresent()) !=null);
textToBePresentInElement() – The expected condition waits for an element having a certain string pattern.
wait.until(ExpectedConditions.textToBePresentInElement(By.id(“title’”), “text to be found”));
wait.until(ExpectedConditions.textToBePresentInElement(By.id(“title’”), “text to be found”));

Please refer very good article on waits:

49. How to connect to a database in Selenium?

Answer:  As we know every application has to maintain a database like My SQL, Oracle or any other databases to store all its data. And where as Selenium Webdriver is used for testing web applications and we perform many operations like submitting information and some times retrieving information and validate them.

In selenium scripts, when there is a need of getting the Data from the database we may have to use APIs which helps to interact with database like JDBC.
Java Database Connectivity(JDBC) is a Java API which is used to connect and interact with Database.
Why do we use JDBC instead ODBC?
ODBC is developed and written in C, which is platform Independent. where as JDBC API is a specification provides set of interfaces which are written and developed in Java programming language.
How to Connect to database using JDBC?
The below are the Steps to Connect to database, before proceeding, you need to have MySQL Connector. You can download from here Download MySQL Connector Jar and add it the build path as we add selenium webdriver jar.
1. Load and Registering the Driver
For registering the Driver we Load the Driver class using forName() method.
forName() is the static factory method which is present in predefined class called "Class". This method loads the class which is mentioned as parameter.
Class.forName("com.mysql.jdbc.Driver");// class.forName load the Driver class
Internally this Driver class will register the driver by using static method called registerDriver().
2. Establishing Connection.
For establishing connection with database we call static method called getConnection(...) present in DriverManager Class. This method contains three arguments of string type. i.e., url, username and password
DriverManager.getConnection("jdbc:mysql://localhost:3306/Employee","root","root");
URL contains "jdbc(main protocol):mysql(sub protocol for mySql)://localhost:3306(sub name for mysql (host:prot))/Employee(database)" and this method return type is Connection Object ie.,
Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/Employee","root","root");
3. Creating Statement Object
For creating statement object we need to call a method called createStatement() which is present in Connection Interface.

con.createStatement();
And this method returns Statement object and it is no argument method.
Statement st= con.createStatement();
4. Execute the Statement
For executing queries there are different methods present in Statement Interface for retrieving records and for updating records.
Retrieving records:
for executing select queries(for fetching records) we call a method called executeQuery(String qry) by taking string as parameter.
st.executeQuery("Select * from Employee");
This method returns ResultSet object.
Resultset rs= st.executeQuery("Select * from Employee");// once executeQuery() executes the query and stores the records in to ResultSet object.
5. Closing the connection.
Once execution of all statements were completed we need to close all the connections by using method called close() present in Connection interface
con.close();
public class TestDatabaseTesting {

 @Test

 public void TestVerifyDB(){

  try {

            
       // This will load the driver

     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

     System.out.println("Driver Loaded");

    // Specify the path of the database

      String dblocation= "C:\\Users\\Desktop\\DB\\FacebookDB1.accdb";


    // This will connect with Database , getConnection taking three argument

    //  first argument Test_Oracle is the dsn which you can change as per your system,

       Connection con=DriverManager.getConnection("jdbc:odbc:AscentAccess;DBQ="+dblocation);           

       System.out.println("Connection created");

   // This will create statement 

        Statement smt=con.createStatement();


        System.out.println("Statement created");

   // Now execute the query, here facebook is the table which I have created in DB

        ResultSet rs=  smt.executeQuery("Select * from Facebook");

        System.out.println("Query Executed");

  // Iterate the resultset now

       while(rs.next()){

       String uname=    rs.getString("username");

       String pass=        rs.getString("password");

       String email=      rs.getString("email");

        System.out.println("Uname is "+uname+" password is "+pass+" email id is "+email);


  }

}

        catch (Exception e) {

         System.out.println(e.getMessage());

  }

 }

}

                }

}

54. How to handle colors in Selenium WebDriver?

Answer:  First of all, we have to get a value of link color using getCssValue method. It can be done by using below code. In the code, Products link’s CSS attribute ‘color’ is stored in a String variable called ‘color’.
We need to return value in RGB format such as “rgba(36, 93, 193, 1)”. We will convert it into more convenient Hex code using Java.
We can add an Assert statement to verify that the color is matching with the expected color.
Please refer below program
public void GoogleAbout() throws Exception{

String color = driver.findElement(By.xpath("//a[@href='products/']")).getCssValue("color");

String[] hexValue = color.replace("rgba(", "").replace(")", "").split(",");

int hexValue1=Integer.parseInt(hexValue[0]);

hexValue[1] = hexValue[1].trim();

int hexValue2=Integer.parseInt(hexValue[1]);

hexValue[2] = hexValue[2].trim();

int hexValue3=Integer.parseInt(hexValue[2]);

String actualColor = String.format("#%02x%02x%02x", hexValue1, hexValue2, hexValue3);

Assert.assertEquals("#245dc1", actualColor);

}

55. Explain how you can switch back from a frame?

Answer: We can even switch to the iframe using web element . We have to come out of the iframe. To move back to the parent frame, you can either use switchTo(). parentFrame() or if you want to get back to the main (or most parent) frame, you can use switchTo()

56. How can you redirect browsing from a browser through some proxy?

Answer: The way of setting it varies depending on Selenium Client Language Bindings and the browser you’re automating, here is an example for Java and Chrome (assuming ChromeDriver and org.openqa.selenium.Proxy)

Please refer below program:
import org.openqa.selenium.Proxy;

import org.openqa.selenium.chrome.ChromeDriver;

import org.openqa.selenium.chrome.ChromeOptions;

public class ChromeWithProxy {

    public static void main(String[] args) {

        Proxy proxy = new Proxy();

        proxy.setHttpProxy("proxyHost:proxyPort");

        proxy.setSslProxy("proxyHost:proxyPort");

        ChromeOptions options = new ChromeOptions();

        options.setProxy(proxy);

        ChromeDriver driver = new ChromeDriver(options);

        driver.get("http://example.com");

        driver.quit();

    }

}

57. Write a code to wait for a particular element to be visible on a page.

Answer: Below is the sample script given
@Test

 public void test() throws InterruptedException, IOException

 {  

  //To wait for element visible

  WebDriverWait wait = new WebDriverWait(driver, 15);

  wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//input[@id='text3']")));

  driver.findElement(By.xpath("//input[@id='text3']")).sendKeys("Text box is visible now");

  System.out.print("Text box text3 is now visible");

    }

58. Write a code to wait for an alert to appear.

Answer: Below is the sample script given
public class Mytest1 {

 WebDriver driver = null;

 @Before

 public void beforetest() {

  System.setProperty("webdriver.gecko.driver", "D:\\Selenium Files\\geckodriver.exe");

  driver = new FirefoxDriver();

  driver.manage().window().maximize();

  driver.get("http://only-testing-blog.blogspot.in/2014/01/new-testing.html");

 }

 @After

 public void aftertest() {

  driver.quit();

 }

 @Test

 public void test ()

  { 

  driver.findElement(By.xpath("//input[@name='fname']")).sendKeys("My Name");

  WebDriverWait wait = new WebDriverWait(driver, 15);

  wait.until(ExpectedConditions.alertIsPresent());

  String alrt = driver.switchTo().alert().getText();

  System.out.print(alrt);

  }

 }

59. How to handle keyboard and mouse actions using Selenium?

Answer:  Please refer below link

60. How can you fetch an attribute from an element?

Answer: The getAttribute() method returns the value of the attribute with the specified name, of an element. Tip: Use the getAttributeNode() method if you want to return the attribute as an Attr object.

61. How to retrieve typed text from a text box?

Answer:  To get the typed text from a textbox, you can use getAttribute(“value”) method by passing arg as value. Value attribute stores the typed text of the textbox element. See the following example to know better:
String typedText = driver.findElement(By.xpath("xpath_textbox")).getAttribute("value"));

62. How to send alt or shift or control or enter or tab key in Selenium WebDriver?

Answer: When we generally use ALT/SHIFT/CONTROL keys, we hold onto those keys and click other buttons to achieve the special functionality. So it is not enough just to specify keys.ALT or keys.SHIFT or keys.CONTROLfunctions.
For the purpose of holding onto these keys while subsequent keys are pressed, we need to define two more methods: keyDown(modifier_key) and keyUp(modifier_key)
Parameters: Modifier_key (keys.ALT or Keys.SHIFT or Keys.CONTROL)
Purpose: Performs a modifier key press and does not release the modifier key. Subsequent interactions may assume it’s kept pressed.
Parameters: Modifier_key (keys.ALT or Keys.SHIFT or Keys.CONTROL)
Purpose: Performs a key release.
Hence with a combination of these two methods, we can capture the special function of a particular key.
Below is the sample script given
public static void main(String[] args)

{

String baseUrl = https://www.facebook.com”;

WebDriver driver = new FirefoxDriver();

driver.get("baseUrl");

WebElement txtUserName = driver.findElement(By.id(Email);

Actions builder = new Actions(driver);

Action seriesOfActions = builder

 .moveToElement(txtUerName)

 .click()

 .keyDown(txtUserName, Keys.SHIFT)

 .sendKeys(txtUserName, hello)

 .keyUp(txtUserName, Keys.SHIFT)

 .doubleClick(txtUserName);

 .contextClick();

 .build();

seriesOfActions.perform();

}

63. How to switch to a new window (new tab) which opens up after you click on a link?

Answer: If you click on a link in a web page, then for changing the WebDriver’s focus/ reference to the new window we need to use the switchTo() command. Look at the below example to switch to a new window:
String handle = driver.getWindowHandle();
//get the name of all the windows that were initiated by the WebDriver
for (String handle : driver.getWindowHandles())
{
    driver.switchTo().window(handle);
}

65. How to check for 404 using Selenium WebDriver?

Answer: Below is the sample script given

    public static void verifyLinkActive(String linkUrl)

                {

        try

        {

           URL url = new URL(linkUrl);

           HttpURLConnection httpURLConnect=(HttpURLConnection)url.openConnection();

           httpURLConnect.setConnectTimeout(3000);

           httpURLConnect.connect();

           if(httpURLConnect.getResponseCode()==400)

           {

               System.out.println(linkUrl+" - "+httpURLConnect.getResponseMessage());

            }

          else

           {

               System.out.println(linkUrl+" - "+httpURLConnect.getResponseMessage()" );

            }

        } catch (Exception e) {

        }

    }

}

66. How to get HTTP Response code using Selenium WebDriver?

Answer: This is a Java library use for general HTTP network communication and includes supports sessions via cookies. Their fluent API makes it relatively simple to get the response code for a URL.
    public int getResponseCode(String url) {
        try {
            return Request.Get(url).execute().returnResponse().getStatusLine()
                    .getStatusCode();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

67. How to stop selenium from creating temporary Firefox profiles using web driver?

Answer: 
1. You can control how the Firefox driver chooses the profile. Set the webdriver.firefox.profile property to the name of the profile you want to use. Most folks think this is a bad idea, because you'll inherit all the cookies, cache contents, etc. of the previous uses of the profile, but it's allowed if you really want to do it.
System.setProperty("webdriver.firefox.profile", "MySeleniumProfile");
WebDriver driver = new FirefoxDriver(...);
2. 
FirefoxProfile profile = new FirefoxProfile(new File("D:\\Selenium Profile"));                 
WebDriver driver = new FirefoxDriver(profile);
Then I changed settings in Firefox to clear all cookies and cache when exiting.

68. How to close browser popup window in Selenium WebDriver?

Answer: There're at least 3 ways to handle this case.
1. Refresh the page and then dismiss the dialog if the driver supports it :
driver.refresh();
driver.switchTo().alert().accept();
driver.quit();
2. Setup the browser oriented driver to avoid the prompt :
// Chrome
ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-popup-blocking");
driver = new ChromeDriver(options);
// Firefox
FirefoxOptions options = new FirefoxOptions();
options.addPreference("dom.disable_beforeunload", true)
WebDriver driver = new FirefoxDriver(options)
3. Add some JavaScript code into the page to escape the prompt:
string JS_DISABLE_UNLOAD_DIALOG = "Object.defineProperty(BeforeUnloadEvent.prototype, 'returnValue', { get:function(){}, set:function(){} });"
((JavascriptExecutor)driver).executeScript(JS_DISABLE_UNLOAD_DIALOG);
driver.quit();

Let’s understand the code which is used for parsing the XML file.
import java.io.File;

import java.util.Iterator;

import java.util.ListIterator;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

import org.w3c.dom.Node;

import org.w3c.dom.NodeList;



public class XMLFileReader {



                public static void main(String[] args) {

                                try{

                                                String filePath = "XMLFilePath";

                                                File file = new File(filePath);

                                                DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

                                                DocumentBuilder dBuilder = dbf.newDocumentBuilder();

                                                Document doc = dBuilder.parse(file);

                                                doc.getDocumentElement().normalize();

                                                System.out.println(doc.getDocumentElement().getNodeName());

                                                NodeList nodeList = doc.getElementsByTagName("account");

                                                int tLength = nodeList.getLength();

                                               

                               

                                for(int i=0; i<tLength; i++){

                                                                Node node = nodeList.item(i);

                                                               

                                                                if(node.getNodeType()==Node.ELEMENT_NODE){

                                                                                Element element = (Element)node;

                                                                                System.out.println("Account No: "+element.getAttribute("acn"));

                                                                                System.out.println("First Name: "+element.getElementsByTagName("firstname").item(0).getTextContent());

                                                                                System.out.println("Last Name: "+element.getElementsByTagName("lastname").item(0).getTextContent());

                                                                                System.out.println("Balance: "+element.getElementsByTagName("balance").item(0).getTextContent());

                                                                }             

                                                }

                                }catch (Exception e){

                                                e.printStackTrace();

                                }

                }

}

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbf.newDocumentBuilder();
These two lines of code create the instance of the DOM architecture of the XML file.
Document doc = dBuilder.parse(file);
doc.getDocumentElement().normalize();
These codes parse the XML file and normalize it for test data retrieval.
We use JavaScript methods to get the texts So here is the entire program to read the test data from an XML file.
Output:
bank

Account No: 001

First Name: Alvin

Last Name: Joseph

Balance: 50000

Account No: 002

First Name: Mark

Last Name: dsouza

Balance: 500

101. If we write FileInputStream statements in try block, what are the statements we will write in finally block?

Answer: Below is the sample script given
close() statement is used to close all the open streams in a program. Its a good practice to use close() inside finally block. Since finally block executes even if exception occurs so you can be sure that all input and output streams are closed properly regardless of whether the exception occurs or not.

public class SimpleExceptionHandling {

                public static void main(String[] args) {

                                FileInputStream fileInputStream = null;

                                try {

                                                fileInputStream = new FileInputStream("C:\\SomeTempFile");

                                } catch (FileNotFoundException e) {

                                                System.out.println("An exception occured :: " + e.getMessage());

                                                System.out.println("Need to close FileStream");

                                } finally {

                                                System.out.println("In Finally Block - Thank God we are here :) ");

                                                try {

                                                                if (fileInputStream != null) {

                                                                                fileInputStream.close();

                                                                }

                                                } catch (IOException e) {

                                                }

                                }

                }

}

Output:
An exception occured :: C:\SomeTempFile (The system cannot find the file specified)

Need to close FileStream

In Finally Block - Thank God we are here :)

106. How to achieve Singleton Design in Selenium WebDriver?

Answer:
What is Singleton Design Pattern?
When we develop a class in such a way that it can have only instance at any time, is called Singleton design pattern. It is very useful when you need to use same object of a class across all classes or framework. Singleton class must return the same instance again, if it is instantiated again.
To create a singleton class, we need to do following steps:
Declare constructor of class as private so that no one instantiate class outside of it.
Declare a static reference variable of class. Static is needed to make it available globally.
Declare a static method with return type as object of class which should check if class is already instantiated once.
class SingletonClassExample

{

    // declaring an instance of class SingletonClassExample which is null initially means not initialized.

    private static SingletonClassExample instanceOfSingletonClassExample = null;

    // Declaring constructor as private to restrict object creation outside of class

    private SingletonClassExample()

    {

        System.out.println("Object created");

    }

    // static method to create instance of class SingletonClassExample

    public static SingletonClassExample getInstanceOfSingletonClassExample()

    {

        if (instanceOfSingletonClassExample == null)

                instanceOfSingletonClassExample = new SingletonClassExample();

        return instanceOfSingletonClassExample;

    }

}

// A normal class where we will try to instantiate class SingletonClassExample

class LetsTryToInstaltiateSingletonClassExample

{

    public static void main(String args[])

    {

        // instantiating Singleton class first time

                SingletonClassExample first= SingletonClassExample.getInstanceOfSingletonClassExample();

        // instantiating Singleton class second time

                SingletonClassExample second= SingletonClassExample.getInstanceOfSingletonClassExample();





    }

}

Output:
Object created

When you run above program, you will get print “Object created.” only once while you have instantiated class twice. This is because of singleton pattern. It will not create object of class again if already initialized once.
How does Singleton pattern help in Selenium Webdriver?
Keep track of same driver instance throughout execution.
DBMS connectivity.
Loading external files like properties, excel etc once rather than loading again and again.
Logger.
So wherever you feel, you should have single instance of any class, you should use singleton design pattern.  For example: If database connection is already established, you should not create new connection.
We will see implementation of singleton design pattern for keep track of driver.
import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;

public class SingletonBrowserClass {

                // instance of singleton class

                private static SingletonBrowserClass instanceOfSingletonBrowserClass=null;

    private WebDriver driver;

    // Constructor

    private SingletonBrowserClass(){

                System.setProperty("webdriver.chrome.driver","./exefiles/chromedriver.exe");

                                driver= new ChromeDriver();

    }

    // TO create instance of class

    public static SingletonBrowserClass getInstanceOfSingletonBrowserClass(){

        if(instanceOfSingletonBrowserClass==null){

                instanceOfSingletonBrowserClass = new SingletonBrowserClass();

        }

        return instanceOfSingletonBrowserClass;

    }

    // To get driver

    public WebDriver getDriver()

    {

                return driver;

    }

}

import org.openqa.selenium.WebDriver;

public class LuanchURL {

                public static void main(String[] args) {

                                SingletonBrowserClass sbc1= SingletonBrowserClass.getInstanceOfSingletonBrowserClass();

                                WebDriver driver1 = sbc1.getDriver();

                                SingletonBrowserClass sbc2= SingletonBrowserClass.getInstanceOfSingletonBrowserClass();

                                WebDriver driver2 = sbc2.getDriver();

                                driver2.get("https://www.google.com");

                }

}

Explanation: When you run LoadURL.java, you will see browser will be launched and url will be opened in same browser. We have instantiated two instance of class SingletonBrowserClass, but both give the same instance of driver.

Answer: Below given webdriver code Is just for example. It Is just explaining the way of using try catch block to handle unexpected alert. You can use such try catch block In that area where you are facing unexpected alerts very frequently.
Below is the sample script given:
public class unexpected_alert {

 WebDriver driver = null;

 @BeforeTest

 public void setup() throws Exception {

  System.setProperty("webdriver.gecko.driver", "D:\\Selenium Files\\geckodriver.exe");

  driver = new FirefoxDriver();

  driver.manage().window().maximize();

  driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

  driver.get("URL");

 }



 @AfterTest

 public void tearDown() throws Exception {

  driver.quit();

 }

 @Test

120. How to check the cursor type changes on hovering on a link?

Answer:  Below is a situation where I had to automate the test which checks that the checkbox is read-only and the cursor does not change its type to 'pointer' after hovering the mouse over that checkbox.
Here's how I achieved it with Selenium.
Solution : There is a CSS value to the element which may change after the hover of the mouse on the element. We can capture the CSS value with selenium's WebElement's method getCssValue().
Here's the test code :
@Test

public void testCursorDoesntChangeOnHover(){

//Identify the element on the hover of which you want to         verify the pointer type

WebElement e = driver.findElement("Element Locator"));

System.out.println("Cursor before hovering on: " + e.getCssValue("cursor"));

System.out.println("Hovering on the element...");

//Hover the mouse over that element

Actions builder = new Actions(driver);

builder.moveToElement(e);

builder.build().perform();

//Check that the cusrsor does not change to pointer

String cursorTypeAfter = e.getCssValue("cursor");

System.out.println("Cursor after hovering on: " + cursorTypeAfter);

//Verify that the cursor type has not changed to 'pointer'

Assert.assertFalse(cursorTypeAfter.equalsIgnoreCase("pointer"), "Cursor type changed !");

}

126. How to add the screenshot to result window?

127. How to enter date into date field using JavaScript in WebDriver?

Answer:  In old applications, the datepicker was in old style, that is, it was a kind of dropdowns, by using select class. But in new applications now, Datepicker are not Select element.
Datepicker are in fact table with set of rows and columns. To select a date, you just have to navigate to the cell where our desired date is present.
So, to handle this datePicker, we will write a java script, in which firstly we will enable the datebox (which is restricted by default to enter the value manually rather than selecting it from calendar pop-up). Then We will clear that filed & then enter the date by using sendKeys() method.
Below is the sample script given
import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;

import org.openqa.selenium.JavascriptExecutor;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.firefox.FirefoxDriver;

public class HandleDatePcikerUsingJavaScript {

 public static void main(String[] args) {

  WebDriver driver = new FirefoxDriver();

  driver.navigate().to("https://www.redbus.in/");

  driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

  driver.manage().window().maximize();

  //This will select From date

  WebElement elementFromDate = driver.findElement(By.id("onward_cal"));

  ((JavascriptExecutor)driver).executeScript ("document.getElementById('onward_cal').removeAttribute('readonly',0);"); // Enables the from date box

  elementFromDate.clear();

  elementFromDate.sendKeys("18-Aug-2017"); //Enter date in required format

 }



}

128. How to take complete screen shot of the application?

Answer: What is aShot?
aShot is a WebDriver Screenshot utility. It takes a screenshot of the WebElement on different platforms (i.e. desktop browsers, iOS Simulator Mobile Safari, Android Emulator Browser).
aShot might be configured to handle browsers with the viewport problem. This gives a screenshot of the entire page even for Chrome, Mobile Safari, etc
Below mentioned script shows how to capture full page screenshot using Selenium WebDriver:
import java.io.File;

import javax.imageio.ImageIO;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

import ru.yandex.qatools.ashot.AShot;

import ru.yandex.qatools.ashot.Screenshot;

import ru.yandex.qatools.ashot.shooting.ShootingStrategies;

public class FullPageScreenshot {

                public static void main(String args[]) throws Exception{

                    //Modify the path of the GeckoDriver in the below step based on your local system path

            System.setProperty("webdriver.gecko.driver","D://Selenium Environment//Drivers//geckodriver.exe");

            // Instantiation of driver object. To launch Firefox browser

                    WebDriver driver = new FirefoxDriver();

            // To oepn URL "https://automationtestinginsider.com"

                    driver.get("https://www.automationtestinginsider.com");

                    Thread.sleep(2000);

                    Screenshot fpScreenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);

                    ImageIO.write(fpScreenshot.getImage(),"PNG",new File("D:///FullPageScreenshot.png"));

        }

}


129. How to take the screen shot of required element?

Answer:  We can get the element screenshot by cropping entire page screenshot as below:
driver.get("http://www.google.com");
WebElement ele = driver.findElement(By.id("hplogo"));
// Get entire page screenshot
File screenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
BufferedImage  fullImg = ImageIO.read(screenshot);
// Get the location of element on the page
Point point = ele.getLocation();
// Get width and height of the element
int eleWidth = ele.getSize().getWidth();
int eleHeight = ele.getSize().getHeight();
// Crop the entire page screenshot to get only element screenshot
BufferedImage eleScreenshot= fullImg.getSubimage(point.getX(), point.getY(),
    eleWidth, eleHeight);
ImageIO.write(eleScreenshot, "png", screenshot);
// Copy the element screenshot to disk
File screenshotLocation = new File("C:\\images\\GoogleLogo_screenshot.png");
FileUtils.copyFile(screenshot, screenshotLocation);

            //to perform Scroll on application using Selenium

            JavascriptExecutor js = (JavascriptExecutor) driver;

            js.executeScript("window.scrollBy(0,350)", "");

         }

}

Output: The code initializes Gecko driver for Firefox. Then the Firefox browser is launched, and it navigates to the specified website URL. Once the website loads, the browser window is vertically scrolled down by 350 pixels.
If a user needs to scroll up, they just need to modify the pixel value of the second parameter (in this case 350) to negative value (-350).

134. How to automate videos?

Answer:  Testing a video is always a challenging task. Most of the video based web sites are manually tested & are out of scope of automation.
However, the javascript executor in selenium webdriver will enable us to play around with the video components. Thus, few of the test scenarios w.r.t video testing can be automated using the below approach.
Below is the sample script given
System.setProperty("webdriver.chrome.driver", "ChromeDriver Path");

WebDriver driver= new ChromeDriver();

//Open the page containing video component.

driver.get("URL");

driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);

//If video is placed in embed tag or iframe, navigate to the source.

//However, we can even switch to frame. [Else, skip this step]

WebElement elm = driver.findElement(By.id("video_iframe"));

String urlStr = elm.getAttribute("src");

System.out.println("Video Url : " + urlStr);

driver.navigate().to(urlStr);

cdrv.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);

JavascriptExecutor jse = (JavascriptExecutor) driver;

//Click on play button

jse.executeScript("jwplayer().play();");

Thread.sleep(2000);

//Pause

jse.executeScript("jwplayer().pause()");

Thread.sleep(2000);

//Play

jse.executeScript("jwplayer().play();");

Thread.sleep(2000);

// Set Volume

Thread.sleep(2000);

jse.executeScript("jwplayer().setVolume(50);");

Thread.sleep(2000);

//Mute Player

jse.executeScript("jwplayer().setMute(true);");

Thread.sleep(2000);

//UnMute Player

jse.executeScript("jwplayer().setMute(false);");

Thread.sleep(2000);

//Stop the player

jse.executeScript("jwplayer().stop()");

Thread.sleep(2000);

driver.quit();

149. Write a program to return the number of rows and columns in a web-table?

Answer:
Image
We need to get WebElement of <tbody> tag, so that we can get the count of <tr> tags & ultimately total number of rows in the web table.
So, Below is the sample code, with which we can get total number of rows in the web table.
WebElement TogetRows = driver.findElement(By.xpath("//table[@id='users_table']/tbody"));
List<WebElement>TotalRowsList = TogetRows.findElements(By.tagName("tr"));
System.out.println("Total number of Rows in the table are : "+ TotalRowsList.size());
In order to get total number of columns in the web table, what we need to do is, count total number of <td> tags in first <tr> tagname.
Below is the sample code, with which we can get total number of columns easily.
WebElement ToGetColumns = driver.findElement(By.xpath("//table[@id='users_table']/tbody/tr"));
List<WebElement> TotalColsList = ToGetColumns.findElements(By.tagName("td"));
System.out.println("Total Number of Columns in the table are: "+TotalColsList.size());

150. 3 frames one upon another, how to switch without passing index, web-element, string and integer?

Answer:  Please refer below link
https://www.automationtestinginsider.com/2020/02/handling-iframes-in-selenium-webdriver.html
Some times when there are multiple Frames (Frame in side a frame), we need to first switch to the parent frame and then we need to switch to the child frame. below is the code snippet to work with multiple frames.
public void switchToFrame(String ParentFrame, String ChildFrame) {

                                try {

                                                driver.switchTo().frame(ParentFrame).switchTo().frame(ChildFrame);

                                                System.out.println("Navigated to innerframe with id " + ChildFrame

                                                                                + "which is present on frame with id" + ParentFrame);

                                } catch (NoSuchFrameException e) {

                                                System.out.println("Unable to locate frame with id " + ParentFrame

                                                                                + " or " + ChildFrame + e.getStackTrace());

                                } catch (Exception e) {

                                                System.out.println("Unable to navigate to innerframe with id "

                                                                                + ChildFrame + "which is present on frame with id"

                                                                                + ParentFrame + e.getStackTrace());

                                }

                }

After working with the frames, main important is to come back to the web page. if we don't switch back to the default page, driver will throw an exception. Below is the code snippet to switch back to the default content.

public void switchtoDefaultFrame() {

                                try {

                                                driver.switchTo().defaultContent();

                                                System.out.println("Navigated back to webpage from frame");

                                } catch (Exception e) {

                                                System.out

                                                                                .println("unable to navigate back to main webpage from frame"

                                                                                                                + e.getStackTrace());

                                }

160. How to handle dynamic web pages?

Answer: A page that has dynamic content has elements of the page that are hidden when you first get to the website. For example, if you were to press a button on a page and it loaded new content, like a pop-up form, without going to another page, that’s a dynamic website. It can also be a user-specific web page that changes day-to-day depending on when it’s accessed, where it’s accessed, user preferences, etc.
Selenium’s Solution
Selenium actually has two built-in solutions for testing dynamic loading content that we recommend you should use: the explicit and the implicit wait.

Answer: It depends on the framework structure you're following to verify an object. If you're following Page object model (POM), then create a base class and define the locator of an object you want to verify. Method to verify its presence looks like (in Java):
 driver.findElement(by)
 or using dynamic wait as:
 WebDriverWait wait = new WebDriverWait(webDriver, 60);
 wait.until(new ExpectedCondition<Boolean>() {
 @Override
 public Boolean apply(WebDriver driver) {
 if(driver.findElement(by) != null)
 return true;
 return false;
 }
 });
