3. Mention the different parts of a test automation framework.

To automate testing, QAs use various software tools and frameworks. When evaluating tools for automating tests, it’s crucial to consider the following factors,

Code-based vs. Low/No code Tools

Some tools, like Selenium, need programming expertise to write test scripts. There are also low-code tools like Testsigma that allow testers to create test steps using plain English. Low/No-code tools make testing more accessible for both technical and non-technical users.

Open Source vs. Commercial

The pricing of the tool varies significantly based on features. Commercial options may be expensive but provide technical support, while open-source alternatives are free but require research for problem-solving.

Ease of Use

Some test automation platforms are complex, requiring extensive training. On the other hand, some are user-friendly and can be employed immediately.

4. Should you automate all testing?

No, one can not automate all types of testing. For example, usability testing, exploratory testing, and accessibility testing are some types of testing that would yield accurate results when done manually by manual testers. In general, a combination of both manual and automated testing is considered best.

5. What is a test environment?

A test environment is a controlled and isolated setup designed on a computer or server for testing software applications before they are deployed into a live or production environment.

In this setup, the tester installs the recently developed application along with its dependencies on the designated machine, creating a simulation of the production environment. This enables testing the program under real-world conditions.

6. What is browser automation?

Browser automation refers to the process of automating tasks and interactions within a web browser. It involves using specialized tools to control and manipulate a web browser just as a human would.

8. Why do you need cross-browser testing?

Cross-browser testing is crucial to ensure the software application works on every browser, device, platform, or version. Since different users use different browsers to access web/mobile web applications, it is important to perform cross-browser testing to ensure the application works perfectly and seamlessly on all browsers, devices, platforms, and versions.

9. What is automated regression testing?

Automated regression testing is the process of automating regression tests for fast and efficient testing. In regression testing, the tester verifies that existing features are not impacted due to code changes. The main goal is to validate that both existing and newly developed functionalities work seamlessly.

  • Create test data (positive and negative) that simulate real-world scenarios. 

11. What is the test automation pyramid?

The test automation pyramid is a concept that represents the ideal distribution of different types of automated tests in a software testing strategy. 

The term test pyramid was introduced by Mike Cohn in his book Succeeding with Agile. The testing pyramid consists of three levels, each representing a different layer of testing, such as, 

  • Unit tests,
  • Integration tests,
  • E2E tests.
