Testing is crucial to the success of any software product. The prime objective of software testing is to get a high-quality output while reducing the cost and the time required for completing the project. But testing to find defects or bugs manually is time-consuming, expensive, often repetitive, and subject to human error. This is where automation comes into the picture. The Automation Testing Course is the perfect guide for you to learn how to be a Test Automation Engineer.
With the adoption of automation becoming more and more widespread, software testers with manual testing skills alone won’t be able to make it in today’s job market. If you are preparing for Automation Testing job interview, you need to be aware of most frequently asked questions in the test automation field. With that in mind, in this article on Test Automation Interview Questions, I will be discussing the top questions related to automation testing asked in the interviews. For your better understanding, I have divided test automation interview questions into the following sections:
- How would you describe the process of automation testing? …
- What automation testing tools are you familiar with? …
- How would you identify test cases that qualify for automation? …
- What are the characteristics of a good software testing framework?

A test is a good candidate for automation under the following conditions.
3. What’s the difference between manual testing and automated testing?
| Manual Testing | Automated Testing |
|---|---|
| A human executes the test cases one by one, without any software assistance. | Tests are executed by a testing tool or framework, without human assistance. |
| Useful for non-repeatable tests that involve human ingenuity, participation, and domain experience. | Useful for repeatable tests where the software feature under test doesn’t change frequently. |
| Good for accessibility and usability testing, as the tester can test the software from an end-user’s perspective. | Good for testing regression issues to make sure that the software didn’t break after introducing new changes. |
| Can be slow and time-consuming, and subject to human errors and misjudgment. | Since it’s run by a computer, automated tests are fast and free from errors, given that we are testing the right thing. |
| It’s possible to test the software in a randomized manner, also known as exploratory testing. | Exploratory testing is not possible in automated testing. |
| UI problems and inconsistencies are easily spotted by a human tester. | Unless it’s programmed for that, the automated testing cannot discover and report the UI problems. |
| It’s very difficult, rather impossible to test the software under extreme load to conduct performance testing. | Performance testing can be easily done with automation testing. |
| The tester doesn’t need prior programming knowledge. | To write automated tests, the tester needs to have prior programming knowledge. |
