Introduction

Selenium is a powerful tool for automating web browsers, making it essential for testing web applications. As the demand for skilled Selenium professionals continues to rise, preparing for interviews becomes crucial. This guide provides you with the top 20 Selenium interview questions and answers to help you land your dream job in 2025.

1. What is Selenium?

Selenium is an open-source framework used for automating web browsers. It provides a suite of tools and libraries that support multiple browsers, programming languages, and operating systems.

2. What are the key components of Selenium Suite?

• Selenium IDE (Integrated Development Environment): A record-and-playback tool for creating simple test scripts.
• Selenium WebDriver: An API that allows you to control web browsers programmatically.
• Selenium Grid: A tool that enables you to run tests on multiple machines and browsers simultaneously.

3. What are the advantages of Selenium?

• Open Source and Free
• Supports Multiple Browsers (Chrome, Firefox, Safari, etc.)
• Supports Multiple Programming Languages (Java, Python, C#, etc.)
• Cross-Platform Compatibility
• Large Community Support

4. What is Selenium WebDriver?

Selenium WebDriver is a collection of language-specific bindings used to drive a browser natively. It directly communicates with the browser and controls it, providing a more stable and efficient automation experience compared to Selenium RC.

5. How to launch a browser using Selenium WebDriver? (Java Example)

 import org.openqa.selenium.WebDriver;
 import org.openqa.selenium.chrome.ChromeDriver;

 public class LaunchBrowser {
  public static void main(String[] args) {
   // Set the path to the ChromeDriver executable
   System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");

   // Initialize ChromeDriver
   WebDriver driver = new ChromeDriver();

   // Navigate to a website
   driver.get("https://www.example.com");

   // Close the browser
   driver.quit();
  }
 }
 

6. What are the different locators in Selenium?

Locators are used to identify web elements on a page. The common locators include:

• ID
• Name
• ClassName
• TagName
• LinkText
• PartialLinkText
• XPath
• CSS Selector

7. What is XPath?

XPath (XML Path Language) is a query language for selecting nodes from an XML document. In Selenium, XPath is used to locate elements in web pages based on their attributes and relationships.

8. Differentiate between absolute and relative XPath.

• Absolute XPath: Starts from the root node and specifies the exact path to the element. It's brittle and can break easily if the DOM structure changes.
• Relative XPath: Starts from any node in the DOM and identifies the element based on its attributes or relationships. It's more flexible and resilient to changes.

9. What are CSS Selectors?

CSS (Cascading Style Sheets) selectors are patterns used to select the HTML elements you want to style. In Selenium, CSS selectors can be used to locate elements based on their attributes, classes, or IDs.

10. How to handle dropdowns in Selenium?

Dropdowns can be handled using the Select class in Selenium. Here’s an example:

 import org.openqa.selenium.By;
 import org.openqa.selenium.WebDriver;
 import org.openqa.selenium.WebElement;
 import org.openqa.selenium.chrome.ChromeDriver;
 import org.openqa.selenium.support.ui.Select;

 public class HandleDropdown {
  public static void main(String[] args) {
   System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
   WebDriver driver = new ChromeDriver();
   driver.get("https://www.example.com/dropdown");

   WebElement dropdownElement = driver.findElement(By.id("dropdown"));
   Select dropdown = new Select(dropdownElement);

   // Select by visible text
   dropdown.selectByVisibleText("Option1");

   // Select by value
   dropdown.selectByValue("value1");

   // Select by index
   dropdown.selectByIndex(1);

   driver.quit();
  }
 }
 

11. How to handle alerts in Selenium?

Alerts can be handled using the Alert interface. Here’s an example:

 import org.openqa.selenium.Alert;
 import org.openqa.selenium.By;
 import org.openqa.selenium.WebDriver;
 import org.openqa.selenium.chrome.ChromeDriver;

 public class HandleAlert {
  public static void main(String[] args) {
   System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
   WebDriver driver = new ChromeDriver();
   driver.get("https://www.example.com/alert");

   // Assuming there's a button that triggers an alert
   driver.findElement(By.id("alertButton")).click();

   Alert alert = driver.switchTo().alert();

   // Accept the alert
   alert.accept();

   // Dismiss the alert
   // alert.dismiss();

   // Get the text of the alert
   // String alertText = alert.getText();

   driver.quit();
  }
 }
 

12. What is the difference between driver.close() and driver.quit()?

• driver.close(): Closes the current browser window that the WebDriver is currently controlling.
• driver.quit(): Closes all browser windows associated with the WebDriver session and terminates the WebDriver process.

13. What are the different types of waits in Selenium?

• Implicit Wait: Tells the WebDriver to wait for a certain amount of time when trying to find an element that is not immediately available.
• Explicit Wait: Makes the WebDriver wait for a specific condition to be met before proceeding further.
• Fluent Wait: Allows you to define the maximum amount of time to wait for a condition, as well as the frequency with which to check the condition.

14. How to implement Explicit Wait in Selenium?

 import org.openqa.selenium.By;
 import org.openqa.selenium.WebDriver;
 import org.openqa.selenium.WebElement;
 import org.openqa.selenium.chrome.ChromeDriver;
 import org.openqa.selenium.support.ui.ExpectedConditions;
 import org.openqa.selenium.support.ui.WebDriverWait;

 public class ExplicitWait {
  public static void main(String[] args) {
   System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
   WebDriver driver = new ChromeDriver();
   driver.get("https://www.example.com");

   WebDriverWait wait = new WebDriverWait(driver, 10);
   WebElement element = wait.until(
    ExpectedConditions.presenceOfElementLocated(By.id("elementId"))
   );

   element.click();

   driver.quit();
  }
 }
 

15. What is Selenium Grid?

Selenium Grid is a tool that allows you to run tests on multiple machines and browsers simultaneously. It consists of a central hub and multiple nodes, where the hub distributes the test executions to the nodes.

16. How to set up Selenium Grid?

Setting up Selenium Grid involves starting a hub and registering nodes to the hub. You'll need to download the Selenium Server standalone JAR file. First start the hub:

 java -jar selenium-server-standalone.jar -role hub
 

Then register the nodes to the hub:

 java -jar selenium-server-standalone.jar -role node -hub http://localhost:4444/grid/register
 

17. What is Page Object Model (POM)?

Page Object Model (POM) is a design pattern in Selenium that creates an object repository for web UI elements. Each web page in the application is represented as a class, and the elements on the page are defined as variables within the class. This makes the code more maintainable and reusable.

18. What are the advantages of using POM?

• Improved Code Reusability
• Enhanced Maintainability
• Increased Readability
• Reduced Code Duplication

19. How to handle multiple windows in Selenium?

Multiple windows can be handled by using the getWindowHandles() method, which returns a set of window handles. You can then switch to a specific window using the switchTo().window(windowHandle) method.

 import org.openqa.selenium.By;
 import org.openqa.selenium.WebDriver;
 import org.openqa.selenium.chrome.ChromeDriver;

 import java.util.Set;

 public class HandleMultipleWindows {
  public static void main(String[] args) {
   System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");
   WebDriver driver = new ChromeDriver();
   driver.get("https://www.example.com/multiple-windows");

   // Assuming there's a button that opens a new window
   driver.findElement(By.id("newWindowButton")).click();

   String mainWindowHandle = driver.getWindowHandle();
   Set<String> allWindowHandles = driver.getWindowHandles();

   for (String handle : allWindowHandles) {
    if (!handle.equals(mainWindowHandle)) {
     driver.switchTo().window(handle);
     // Perform actions in the new window
     driver.close();
    }
   }

   driver.switchTo().window(mainWindowHandle);
   // Perform actions in the main window

   driver.quit();
  }
 }
 

20. What is the difference between findElement() and findElements()?

• findElement(): Returns the first matching element on the page. If no element is found, it throws a NoSuchElementException.
• findElements(): Returns a list of all matching elements on the page. If no elements are found, it returns an empty list.
