What are the benefits of automation testing?

When you're asked this question, be sure to describe what your priorities are in automation testing and what you perceive to be a benefit. Use real-life examples of when automation testing has helped you in your field. Be sure to research the company you're applying to beforehand because you can connect your experience in automation testing to their priorities.

Example: "Testing software and processes can be beneficial for those who want to save their resources by hiring fewer professionals to run tests on software. Automation testing doesn't require additional human intervention to run processes and can run overnight. Automation testing makes it easier for professionals to find errors in software. This way, companies reduce costs, assign employees to other tasks or departments, and increase overall productivity."

Which frameworks do you prefer to work with?

When being presented with this question, candidates need to discuss which frameworks they've worked with in the past and why they prefer some frameworks over others. This shows the recruiter or interviewer that, while you have preferences, you have experience with several frameworks. Also, express your interest in discovering other frameworks.

Example: "My favourite framework is data-driven because I prefer navigating test scripts and data. That being said, I've also been doing research on keyword-driven data and started exploring it. At my previous place of employment, we worked primarily with linear scripting and hybrid frameworks."

Have you ever counted the maximum number of tests you automated in one shift? If so, how many did you automate?

This answer requires some explanation on your end; after all, the number of tests you automate depends entirely on the size of the tests. When you're working on large projects, you may only have time to work on one, however, you could work on several dozen smaller tests in a work shift. Take this opportunity to describe what your day-to-day operations are like and how many tasks you can complete.

Example: "A few years back, my coworker and I did a competition on how many tests we could complete in a day. The exact number depends on the size of my tests. If I'm working on big tests, I can do approximately three. If, on the other hand, I'm dealing with tests that are of intermediate complexity, I can do five or six. With smaller tests, I can complete a dozen in one shift. When I'm working on bigger tests, I break them into smaller tasks."

What do you know about Selenium?

This question is asked to gauge what your skill level is as an automation tester. Selenium is a free tool, common among automation testers. If you don't have any experience with Selenium, consider discussing an alternative tool that can perform the same tasks. If you have experience with Selenium, discuss what that experience was like.

Example: "Selenium is an automation testing tool that deals primarily with functional and regression testing. It also allows automation testing in several languages like Java and PHP. I don't have extensive experience in Selenium. However, I do have experience with the script languages it uses, like Python. The experience I have with this tool has been positive, so I would appreciate the opportunity to use it again."

When you're doing automation testing, how do you decide which case to test?

This question is asked to determine how you execute tasks and how you prioritize which cases to test. When answering this question, be sure to mention how you analyze automation tests and the data you receive. Also, be sure to use real-life examples when answering this question.

Example: "The first thing I do when determining which cases to test is to separate which cases are most essential to the business I work for. If the test case is just an end-to-end scenario, it won't be my highest priority when testing cases. Depending on our automation needs, I then arrange the execution frequency. Because I always work more efficiently than manual execution, I then pick a timeframe to analyze the results of the automation test. I make sure the time I take to analyze the results doesn't exceed the time it would take to conduct manual tests."

Are there specific tools you use for testing? If so, how do you choose which tools to use?

The interviewer is trying to get a better sense of how you work and which tools you use when you do. Take this opportunity to demonstrate your skills as an automation tester and provide the interviewer with real-life examples.

Example: "The first thing I do is determine which tests I want to run on cases. From there, I can decide which tools I want to use by researching which ones support the requirements of my project. I also look at my employer's budget and which resources we have at our disposal. There are some tools I prefer using, however, I'm open to any tool and often research new tools when beginning automation testing. My overall goal is to find tools that perform the tests I need them to within my company's budget."

One of my professors gave me the opportunity to work as an automation tester in a big project, and I knew that this was the field I wanted to work in."

Which scenarios should you avoid using automation to test cases?

This question determines whether you know when to perform manual tests or when to find another testing method. In your answer, mention that the key to determining whether you should perform automation tests is to figure it out in the beginning stages of your case.

Example: "It's most appropriate to use automation tests when I'm going to save time and resources by doing so. If I analyze a case and determine that I can execute the tests more quickly by doing it manually, I avoid doing automation tests."
