Core Concepts in Automation Testing

Test Automation Framework

A test automation framework is a set of rules, tools and practices to create and manage automated test scripts. Data-Driven, Keyword-Driven and Hybrid are common frameworks.

Test Scripts

Test scripts are automated sequence of instructions that perform specific actions on the application under test. These are written in programming languages and testing tools.

Test Run

Test run is the process of running automated test scripts on the application to validate the functionality and performance. Results are recorded and analyzed to identify defects and issues.

CI and CT

CI is a development practice where code changes are checked in to a shared repository. CT is running automated tests as part of the CI process to make sure code changes do not introduce new defects.

Test Reporting

Test reporting is generating reports that summarizes the results of automated test runs. These reports help stakeholders to know the status and quality of the application.

TCS Automation Testing Interview Questions

1. What is Automation Testing?

Answer: Automation testing uses software tools to run pre-scripted tests on a software application before it goes to production. The main goal is to automate repetitive and time consuming testing tasks, to increase efficiency and accuracy.

2. What are the advantages of Automation Testing?

Answer:

• Efficiency: Automation testing reduces the testing time.
• Accuracy: Automated tests are less human error prone.
• Reusability: Test scripts can be used across different projects.
• Cost Effective: Reduces the overall cost of testing in long run.

3. What is the difference between Automation Testing and Manual Testing.

Answer:

• Automation Testing: Uses automated tools to run tests. It is faster and more accurate but requires initial investment in tools and script development.
• Manual Testing: Involves human testers to execute test cases. It is slower and human error prone but is useful for exploratory and usability testing.

4. What are the types of Automation Testing frameworks?

Answer:

• Linear Scripting: Simple record and playback model.
• Data-Driven Framework: Uses external data sources to drive test cases.
• Keyword-Driven Framework: Uses keywords to represent actions.
• Hybrid Framework: Combines two or more frameworks for better efficiency.

5. Which tools have you used for Automation Testing?

Answer: Selenium, QTP/UFT, TestComplete, Appium, JUnit are common automation testing tools. The choice of tool depends on the project requirements.

6. How do you decide which test cases to automate?

Answer:

• Repetitive Tests: Tests that need to be run frequently.
• Critical Tests: Tests that cover critical functionality.
• High-Risk Tests: Tests that have high impact on the application.
• Stable Tests: Tests that are not likely to change often.

7. What is Source List in SAP MM?

Answer: A Source List in SAP MM is a list of approved vendors for a material over a period of time. It ensures the right supplier is chosen for procurement based on criteria like delivery time, quality and price.

8. What are the common issues in Automation Testing?

Answer:

• Initial Setup Cost: Cost of automation tools and script development.
• Maintenance: Scripts need to be updated regularly.
• Complexity: Complex test cases are difficult to automate.
• Skill: Skilled personnel required for scripting and maintenance.

9. How do you handle exceptions in your scripts?

Answer:

• Try-Catch Blocks: Use programming constructs to catch and handle exceptions.
• Assertion Methods: Validate expected results and handle failures.
• Logging: Log to troubleshoot issues.

10. What is Selenium and how is it used in Automation Testing?

Answer: Selenium is an open-source automation tool for web applications. It supports multiple languages (Java, Python, C#) and browsers. Selenium WebDriver is used for browser based regression testing and suites.

11. What is Test Automation Framework?

Answer: A test automation framework is a set of rules, tools and practices to create and manage test scripts efficiently. It increases reusability, maintainability and scalability of automated tests.

12. How do you ensure automated tests are reliable?

Answer:

• Stable Environment: Ensure a stable environment.
• Regular Maintenance: Update and maintain scripts regularly.
• Full Coverage: Cover all scenarios.
• Error Handling: Robust error handling in scripts.

13. What is Continuous Integration (CI) and Continuous Testing?

Answer:

• Continuous Integration (CI): Code changes are committed to a shared repository frequently.
• Continuous Testing: Automated tests are run as part of CI to ensure code changes don’t break.

14. What is Test Reporting and why is it important?

Answer: Test reporting is generating reports that summarizes the results of automated test runs. These reports help stakeholders to understand the status, quality and stability of the application under test.

15. How do you handle dynamic elements in your scripts?

Answer:

• XPath: Use dynamic XPath.
• CSS Selectors: Use CSS to locate elements.
• Waits: Implement explicit and implicit waits to handle asynchronous.

16. What is Test Suite in Automation Testing?

Answer: A test suite is a collection of test cases to be executed together. It helps in organizing and managing test cases based on functionality, module or priority.

17. How do you verify the results of your automated tests?

Answer:

• Assertions: Use assertions to validate expected results.
• Verification Points: Use verification points in scripts.
• Manual Review: Manually review logs and reports to ensure accuracy.

18. What is Data-Driven Testing?

Answer: Data-driven testing is using external data sources (like Excel, CSV, databases) to drive test cases. It helps in testing the same functionality with multiple data sets.

19. How do you maintain your test scripts?

Answer:
