1. What is Automation Testing?
Ans:
Automation testing involves using scripts and specialized tools to run test cases automatically on software applications. Its main purpose is to increase test coverage, accelerate the testing procedure and minimize manual work by repeatedly checking the software’s functionality, performance and reliability.
2. What are the advantages of Automation Testing?
Ans:
Automation testing offers several benefits like reusing test scripts, covering more test scenarios, running tests faster and minimizing human mistakes. Additionally, it facilitates continuous delivery and integration, which makes it vital for agile teams and frequent regression testing.
3. How is manual testing different from automation testing?
Ans:
Manual testing means testers execute test steps by hand, which can be slow and prone to errors. Automation testing uses scripts and tools to perform tests automatically, providing faster, more accurate and scalable results especially for repetitive testing tasks.
4. Which frameworks are commonly used for automation testing?
Ans:
Popular automation frameworks include Linear Scripting, Modular, Data-Driven, Keyword-Driven and Hybrid frameworks. Each is designed for different project needs, focusing on script reuse, ease of maintenance and handling complexity.
5. Which tools have you used for automation testing?
Ans:
Some widely used automation tools are Selenium for web apps, JUnit and TestNG for unit tests, Apache JMeter for performance checks, Appium for mobile app testing and Cucumber for behavior-driven development. The choice depends on the project’s requirements.
6. How are the test cases selected for automation?
Ans:
Tests that are repetitive, high-risk, time-consuming or run frequently are best suited for automation. Stable test cases with clear expected outcomes, like regression, smoke and integration tests, are prioritized for automation.
7. What is the Source List in SAP MM?
Ans:
In SAP MM, a Source List keeps track of approved vendors or supply sources for a material during a specific time frame. It simplifies procurement by highlighting preferred vendors and helps automate the selection process when creating purchase orders.
8. What common challenges arise in automation testing?
Ans:
Some issues include flaky tests caused by dynamic UI elements, difficulties maintaining scripts when interfaces change, high initial setup costs and lack of adequate test data. Choosing the wrong tools or having insufficient expertise can also hinder success.
9. How do you handle exceptions in automation scripts?
Ans:
Exception handling involves using try-catch blocks, custom error handlers and logging to manage errors during test execution. Frameworks often provide built-in features for handling timeouts and unexpected events to ensure tests fail gracefully or continue smoothly.
10. What is Selenium and how is it used in automation testing?
Ans:
A well-liked open-source program for web browser automation is called Selenium across multiple platforms and browsers. It supports languages like Java, Python and C# and integrates with frameworks like JUnit and TestNG. Selenium enables simulation of user actions and can be connected to CI/CD pipelines for continuous testing.
