Xchanging – Selenium Interview Questions

Here is the list of Selenium Interview Questions which are recently asked in Xchanging company. These questions are included for both Freshers and Experienced professionals. Our Selenium Training has Answered all the below Questions.

1. How do you implement wait mechanisms in selenium?

As the web pages may load at different speeds, use an Explicit Wait to ensure that Selenium waits until the text becomes visible on the page.

Locate text using XPath: To find the text, use //*[contains(text(),’Your Text’)].
Wait until the element is visible: Use ExpectedConditions.visibilityOfElementLocated() for the text to appear.
Use a loop and clicking the “Next” button to move through each page where the text might appear

2. What type of framework do you use?

Types of Framework:

Linear Automation Framework.
Modular Based Testing Framework.
Library Architecture Testing Framework.
Data-Driven Framework.
Keyword-Driven Framework.
Hybrid Testing Framework

For example:

I used Linear Automation Framework. The main advantage of using this as Record and Playback’ in a linear fashion.

3. What are your regular selenium activities?

For example:

Understanding the requirements of features to be automated and getting it in automation roadmap.
To Monitor daily executed automation script result.
Raise defect or fix script based on failure analysis.
Understanding best practices in automation.
Identify code optimization area to make execution faster.
IC integration, reporting, better logging, code optimization etc.

4. How do you manage test data for Selenium tests?

Three methods are used here,

The elementary approach.
Refresh your data source.
The selfish data generation approach.

5. Do you know RDBMS and what do you use?

Yes, It is a relation database. A relational database organizes data into tables which can be linked or related based on data common to each. This capability enables you to retrieve an entirely new table from data in one or more tables with a single query.

It also allows you and your business to better understand the relationships among all available data and gain new insights for making better decisions or identifying new opportunities.

6. How do you make reporting in Selenium?

To generate reporting in selenium with three methods.

emailable-report.html
index.html
Reporter Class

Need to Switch your career to automation:

7. How do you verify a given login button is named as “SignUp” and how will you confirm it is not “Login”?

Test Cases For a Signup Page

Buttons.
Required Fields.
Optional Fields.
Email Validation.
Phone number Validation.
Password Validation.
User Interface.

8. What statement do you use verify specific error message in the application?

import org.openqa.selenium.By; import org.openqa.selenium.firefox.FirefoxDriver; import org.testng.Assert; import org.testng.annotations.Test; public class TestNaukri { @Test public void TestError() { // Open browser FirefoxDriver driver=new FirefoxDriver(); // maximize browser driver.manage().window().maximize(); // Open URL driver.get(http://www.naukri.com/); // Click on login button driver.findElement(By.id(p0submit)).click(); // This will capture error message String actual_msg=driver.findElement(By.id(emailId_err)).getText(); // Store message in variable String expect=plz enter valid email; // Here Assert is a class and assertEquals is a method which will compare two values if // both matches it will run fine but in case if does not match then if will throw an //exception and fail testcases // Verify error message Assert.assertEquals(actual_msg, expect); } }

9. How do you switch between different windows in Selenium?

Switching between different windows can be done using the driver.switchTo().window() method.

Before opening a new window or tab, store the current window handle using driver.getWindowHandle(). After opening a new window or tab, use driver.getWindowHandles() to retrieve a set of all window handles.

driver.switchTo().window can be used to switch between different windows. Once the window is switched, interact with the elements of that window or tab.

10. Explain the framework that we have worked?

For example, You have to explain each component of your Framework Architecture and you have to specify right from the point of the Test Automation execution to generating the reports.

11. What jar file is used for excel and why?

The most importantly in many projects JXL API is used for excel.

12. What build tool is used and whether we have exp in maven?

For example, Maven tool is used in my project. Maven is built using a plugin-based architecture that allows it to make use of any application controllable through standard input.

13. What is inheritance?

The capability of a class to derive properties and characteristics from another class is called Inheritance. Inheritance is one of the most important feature of Object Oriented Programming.

14. What is Selenese?

Selenium commands, also known as Selenese are the set of commands used in Selenium IDE that run your tests. A sequence of Selenium commands together is known as test script.

15. What are the limitations of Selenium?

The top 3 limitations of selenium given below,

No support for desktop applications.
No support for REST and SOAP Platforms.
No Reporting capability.

16. What unit framework is used?

Java is the main for selenium. The JUnit and NUnit are mainly used unit framework.

17. How reports are generated?

The below two methods are used to generate reports:

18. How do we write test cases?

Following are the important points to write test cases:

First of all, test Cases need to be simple and transparent

The most important thins is to create Test Case with End User in Mind

Also, Avoid test case repetition

Importantly, Do not Assume

Ensure 100% Coverage

Identifiable test case

Implement Testing Techniques.

Peer Review.

19. Asked to write some manual test cases

Test Case for a Mobile:

Check the battery and Sim for correct insertion.
proper operation of Switch ON and Switch OFF functions.
To access Incoming call.
To access outgoing call.
Etc.,

20. How do we handle dynamic web elements in webpage?

Below methods are used to handle dynamic web elements in web page:

Absolute Path method.
Use Relative XPath.
Identify by index.
Use Multiple attributes to locate an element.

21. If a text is displayed in different places in all subsequent pages how do we handle it?

If the same text is displayed in different places on all subsequent pages using Selenium, use the following steps:

1. Identify the Element by Its Unique Property using a locator strategy such as XPath or CSS Selectors.

2. Use Loops to Navigate Through Pages and find the element containing the text and perform the necessary action.

3. Implement a Wait Mechanism to ensure that Selenium waits until the text becomes visible on the page before interacting with it.

22. What are the framework used?

Top frameworks are:

Data-driven framework.
Keyword driven framework.
Hybrid framework.

23. Whether we worked on custom framework and existing framework – product and what are the possible aspects from the custom framework and existing framework to develop the project from scratch?

To develop a project from scratch using Selenium, create a custom framework or use an existing framework.

Custom Framework: is built from scratch based on the project’s specific needs. This allows for flexibility and customization in how you structure the automation.

Existing Framework: is a pre-built, open-source automation framework like TestNG, JUnit, or Cucumber.

To perform test design use Page Object Model (POM) and Page Factory for maintainability. Use TestNG or JUnit for running tests and managing test suites. Integrate with Maven/Gradle for project dependencies and build automation. Implement reporting tools like Allure or ExtentReports for detailed test reports. Leverage Selenium Grid for parallel execution across multiple browsers/environments. Automate tests using Jenkins or GitLab CI for continuous integration and delivery.

24. How we build framework?

Every user interface design starts with an empty artboard, and every designer has a process they use to transform that blank canvas into a fully functioning product.

This process includes all the small design components created, and the steps the designer goes through to build a cohesive whole, from colors to buttons and everything in between.

25. If there are severity 1 test cases in all modules to automate how do we select and automate?

Understand the concept of priority and severity well.

Always assign the severity level based on the issue type as this will affect its priority.

Understand how a particular scenario or Test Case would affect the end-user.

Need to consider how much time it would take to fix the defect based on its complexity and time to verify the defect.

26. How parallelly TestNG can be executed?

import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.chrome.*; import org.testng.annotations.Test; public class ParallelTest { public WebDriver driver; @Test public void FirefoxTest() { //Initializing the firefox driver (Gecko) driver = new FirefoxDriver(); driver.get(https://www.demoqa.com); driver.findElement(By.xpath(//*[@id=\app\]/div/div/div[2]/div/div[1]/div/div[1)).click(); driver.quit(); } @Test public void ChromeTest() { //Initialize the chrome driver driver = new ChromeDriver(); driver.get(https://www.demoqa.com); driver.findElement(By.xpath(//*[@id=\app\]/div/div/div[2]/div/div[1]/div/div[1])).click(); driver.quit(); }

27. If 1 thread of 1 machine is dependent on the 3rd thread of another machine how can we execute it?

Selenium Grid and a synchronization mechanism can be used to run tests across multiple machines using different threads.

Selenium Grid allows you to run tests in parallel controlled by a central Hub. Each machine can execute its own thread, but they would run independently.

28. How to run the scheduler and to run the bat file?

Below steps are followed to run the scheduler

Go to control panel.
Administrative tool.
Task scheduler and create a task which will trigger run.bat file at the time you want.

29. If there are 10 link boxes with 10 unique fields each box have then how many permutations we can have test cases…I said 10 to the power 10 if so is it possible to do automation and how?

To automate high combinatorial test cases, Use pairwise or combinatorial testing. It covers combinations of input values with a smaller subset of test cases by ensuring that every pair of input values is tested at least once.

Pairwise Testing focuses on testing combinations of two variables at a time. It reduces the number of test cases without sacrificing much coverage.

30. Why should Selenium be selected as a test tool?

Following are the reasons,

Platforms and Browsers supported by Selenium.
Visibility in End-to-End Testing.
Integration With Other Tools.
Reduces Turnaround Time.
