Automation Interview Questions


Introduction


Are you preparing for an automation testing interview at top multinational companies like TCS, Infosys, Capgemini, HCL Tech, and others? This blog post is here to help you out! We have compiled a list of common automation testing interview questions that are frequently asked in these companies. Whether you are a fresher or an experienced candidate, this list will give you an idea of what to expect and how to prepare for your interview. So, let's dive in!


Q1. What is automation testing, and why is it important?

Ans: Automation testing is the process of using automation tools to execute test cases and compare the actual results with expected results. It helps in increasing the efficiency, effectiveness, and coverage of software testing. With automation testing, repetitive tasks can be automated, saving time and resources.



Q2. What are the benefits of automation testing?

Ans: Automation testing offers several benefits, including:

  • Faster and more accurate test execution.

  • Increased test coverage.

  • Reusability of test scripts.

  • Improved reliability and maintainability.

  • Early detection of defects.

  • Reduction in overall testing costs.


Q3. Which automation testing tools have you worked with?

Ans: Mention the automation testing tools you have experience with, such as Selenium WebDriver, Appium, TestComplete, JUnit, TestNG, Cucumber, etc. Be prepared to discuss your experience and how you have utilized these tools in your projects.



Q4. What is Selenium WebDriver, and how does it work?

Ans: Selenium WebDriver is a popular automation testing tool used for web applications. It provides a programming interface to interact with web elements, perform actions, and retrieve information. It communicates directly with the browser using the browser's native support for automation. It supports multiple programming languages like Java, C#, Python, etc.



Q5. Explain the difference between Selenium WebDriver and Selenium IDE?

Ans: Selenium WebDriver is a robust automation tool for web applications, while Selenium IDE is a record and playback tool. WebDriver allows you to write code in various programming languages and offers more flexibility for complex scenarios, whereas IDE is limited to recording and playing back user actions.



Q6. How do you handle dynamic elements in automation testing?

Ans: Dynamic elements on a web page are those whose properties change dynamically with each load or action. You can handle them using techniques like wait statements, XPath, CSS selectors, or regular expressions. You can also use explicit waits and expected conditions to wait for an element to appear before interacting with it.



Q7. What are test frameworks, and which ones have you used?

Ans: Test frameworks provide a structure and set of guidelines for writing and executing test cases. Mention the test frameworks you have experience with, such as TestNG, JUnit, Cucumber, or any other frameworks specific to your programming language. Explain how you have utilized these frameworks to organize and execute your test cases effectively.



Q8. How do you handle exceptions and errors in automation testing?

Ans: When an exception or error occurs during test execution, handling them gracefully is important. You can use try-catch blocks to catch exceptions and execute alternative steps or fail the test case. You can also log errors and exceptions for further analysis and debugging.



Q9. What are data-driven testing and keyword-driven testing?

Ans: Data-driven testing involves executing the same test case with different sets of test data. The test inputs and expected results are stored in external data sources like Excel sheets, databases, XML files, etc. Keyword-driven testing is a technique where test cases are designed using keywords or action words. These keywords are mapped to specific functions or methods in the automation framework.



Q10. How do you ensure the stability and robustness of automation test scripts?

Ans: To ensure stability and robustness, you should follow best practices like:

  • Writing modular and reusable code.

  • Using proper synchronization techniques.

  • Implementing exception handling and error logging.

  • Regular maintenance and updates to accommodate changes in the application under test.

  • Thoroughly testing the test scripts on different environments and configurations.


Final words:


Remember, while preparing for an automation testing interview, not only should you focus on answering these questions but also understand the concepts and principles behind them. Practice coding, solve hands-on exercises, and be ready to showcase your skills during the interview. Good Luck!
