This blog on Selenium Interview Questions and answers will helps in gaining you a knowledge on selenium domain.

Selenium Interview Questions and Answers


An open-source tool for automating frameworks is called Selenium. With the help of this programme, web applications may be evaluated while being recorded and played back. It can also execute several scripts in many browsers at once.

  • It allows users to reuse existing functions and run them with virtual concurrent users. It can be used in multiple programming languages like Java, Python, Php, NodeJs, C#, Perl, and Ruby, among others. It also supports OS mobile applications like ISO, windows, and android.
  • The automation tools Maven, Jenkins & Docker, TestNG & JUnit manage and generate the reports. Selenium is easily deployed on Windows, Linex, Solar, and Macintosh platforms.
  • Scripts are executed on each browser instance for your device by the browser device. Below is an explanation of how these components work.

Selenium IDE:

Selenium IDE ( Integrated Development Environment ) is primarily a record or run tool. An extension is available for both firefox and chrome to generate tests quickly through the functionality of record and playback. We don’t need any scripting language for testing any authoring function.

Selenium RC:

In this case, working with RC ( Remote Control ), one must know the knowledge of at least one programming language. We allow the development of a responsive design test with the tool. Server and client libraries are the two main components in selenium RC.

Selenium WebDrive:

Selenium WebDrive is an enhanced version of RC. Though it was an advanced RC version, its architecture differs entirely from RC. Selenium WebDrive also supports multiple programs to provide a more comprehensive and fixable, required-to-know programming language.

Selenium Grid:

Selenium Grid is a tool for test cases in different browsers, machines, and operating systems. This tool makes easy compatibility testing. There are two versions of grid one grid 1, an older version, and the recent version grid 2.

Type of selenium certification

In this field, Selenium is likely one of the best options for helping developers in automating testing. Its importance will increase in the years ahead. Recent graduates with computer science and software engineering degrees can easily land high-paying jobs in this field. You can also pursue other Selenium certifications like:

Selenium with Python

Selenium interview questions and answers for freshers

Here are the interview questions and answers for experienced in the advanced level of Selenium. There was a demand for automation testing. Most of the interview questions were asked during the selenium job interviews. Here are the most asked selenium interview questions and answers for beginners and experienced.

1. How to select the dropdown value?

Three syntaxes were used to select the dropdown values.

  • Select value: Select selectByValue = new Select (driver.findElement(“selectID_one”)));
  • SelectByValue. selectByValue(“greenvalue”);
  • Selectby visibletext: SelectselectByVisibleText= new Select (driver.findElement(“SelectID_Two”)));
  • selectByVisibleText.selectByVisibleText(“Lime”);
  • Selectbyindex: Select selectByIndex = new Select(driver.findElement(“SelectID_Three”)));
  • selectByIndex.selectByIndex(2);

2. What are the types of navigation commands? explain.

  • navigate().back(), navigate().forward(), navigate().refresh(), navigate().to(), these are the four types of navigation commands used in the web page browser.
  • navigate().back(): In this command not required a parameter to take back the user’s previous web page in the web browser history.
  • navigate().forward(): In this command is used to navigate the next web page concerning the browser history.
  • navigate().refresh(): This command let the user refresh the current web page by reloading all the web elements.
  • navigate().to(): This command let the user launch a new browser window and navigate the specific URL.

3. How does the switch to the command used?

  • Within an application, using the switch() method allows switching between windows, frames, or pop-ups. A unique alphanumeric value “Window Handle” is assigned to every window instantiated by the WebDriver.
  • Get the window you wish to switch to
  • String handle= driver.getWindowHandle();
  • Switch to the desired window
  • driver.switchTo().window(handle);
  • Alternatively
  • for(String handle= driver.getWindowHandles())
  • { driver.switchTo().window(handle); }

4. How do we use mouse hover on web drive?

The user can exploit to automate mouse and keyboard events. And the action interface is the single user interface action. Here the following action interface to mouse hover on a dropdown opens a list


// Instantiating Action Interface
Actions actions=new Actions(driver);
Actions actions=new Actions(driver);
actions.moveToElement(driver.findElement("id of the dropdown"))).perform();
// Clicking on one of the items in the list options
WebElement subLinkOption=driver.findElement("id of the sub link"));;

5. What are the stratpoint and breakpoint in selenium?

Breakpoint: Breakpoints allow the flow of execution to be stopped. By performing this test, we can determine if the code is functioning as expected.

Startpoint: The starting point of execution determines the point where the execution should begin. These are used when running a test script from the middle of a program or a breakpoint.

6. What are the differences between remote WebDrive and WebDrive?

WebDriver is an interface that allows communication with a browser, while a RemoteWebDriver is a driver with a browser on a remote machine

7. What are cookies and sessions in selenium?

A cookie is a small of data stored on the user’s computer. A session is a group of related interactions between the user and the website.

8. What is the difference between POM and PF?

POM page object module is a class that represents the web page and holds the functionality. PF page factory, the web elements within the page object when the instance is created.

9. How set the size in a browser window using selenium?

To maximize the size of the browser window use the following code.

driver.manage().window().maximize(); – To maximize the window

To resize the browser window in a particular dimension use the setsize() method. Below code.

Dimension d = new Dimension(420,600);
To set window in a particular size, use window.resizeTo()method.
((JavascriptExecutor)driver).executeScript(“window.resizeTo(1024, 768);”);

10. How do you use to upload the selenium file?

The file is on the same machine or in a mapped network drive, We have to just type the ‘path’ of the file in the FileUpload control.

driver = webdriver.Firefox()
element = driver.find_element_by_id(“fileUpload”)

11. What is setspeed() and sleep() method?

Setspeed(): Sets the execution of speed with a delay of a millisecond, followed by the selenium operation. By default, the delay is 0 milliseconds.

Sleep(): execution of a current thread for a specific period.

12. Mention different types of TestNG?

  • Configurable
  • ISuiteListener
  • IExecution listener
  • IHookable
  • IAnnotation transformer
  • IMethod interceptor
  • IConfiguration listener
  • IInvokedMethodListener
  • ITestListener

13. Is any possibility to find a broken link in selenium WebDrive?

Diven links are broken or not by using the following processes:

Accumulate all the links on a web page using the < a > anchor tag, and use the attribute ‘href’ value to obtain hyperlinks.

Send a request from HTTP for each link and verify the code.

HTTP response code to determine if the link is valid or broken. Use the driver.get() navigate the URL, which is a response with a status of 200-ok ( is this indicating that the link is working ). If we get any other status, it indicates the link is broken.

And Repeat the same process for all the links.

14. What are the types of waits available in WebDriver?

There are two types of waits in WebDriver:

Implicit wait: The implicit wait provides a default waiting time (30 seconds) before the consecutive step across the entire test script. Hence, the subsequence test step is executed when the 30 seconds are over after executing the previous test steps.

Explicit wait: these waits are used to halt the particular condition is met or the maximum time has elapsed.

15. Explain the assert and verify commands?


Assert command checks whether the command is true or false. This command checks if the given element appears on the web page. In the case of an actual condition, the next test would be executed, while if the condition is false, the execution will stop, and the test would not be executed.


we check if the given command is true or false. The program executes without stopping regardless of whether the condition is true or false. The verification process does not stop in the event of a failure, and all test steps will still be executed.

16. Describe Xpath

By using an XML path to identify a web element, an Xpath is generated. XML stands for Extensible Markup Language and is used for storing, organizing, and transporting data.

It stores key-value pairs, which are very similar to HTML tags. The Xpath element can be found in the HTML element since they are under the same umbrella.

17. What are the benefits of automation testing?

  • Support the execution and repeat the test cases
  • Aids and large test matrix
  • Enables parallel execution
  • Encourage unattached execution
  • Improve accuracy
  • Reducing human errors

18. How to create object repository selenium?

Object repository is a term used to refer to the collection of web elements belonging to the application under test ( AUT ) with their locator value required within the script. Object repository is used to store locator in a centralized location instead of hardcode within the script.
