2. What is exploratory testing, and when do you use it?

Not all QA interview questions are about black-box or white-box testing, so you should be prepared to answer various kinds of questions, including exploratory testing. As exploratory testing is only needed in a handful of cases, it might be tricky for the candidate to come up with suitable situations.

Answer: Exploratory testing is a different approach to the testing process where you explore the application during the test rather than having a predefined plan. It requires the tester to identify the areas of dynamic improvement, issues, and potential defects. There are several instances where you might use exploratory testing:

  • There are new testers in the project
  • You need to minimise test script writing
  • New features should be tested
  • The user experience should be tested

3. How do you test a complex API that involves multiple endpoints and integrations?

This is also one of the interview questions for QA that you can come across, especially if the position requires the development and execution of a comprehensive test plan for a complex API. It might be less than trivial for some candidates as it requires the tester to have a deep understanding of API testing concepts and techniques.

Answer: Here is how you should test a complex API with multiple endpoints and integrations:

  • Understand the requirements and specifications for API
  • Plan performance, security, and scalability tests that you would normally use when testing an API
  • Create test cases that cover endpoints and integrations, including positive and negative scenarios
  • Design tests to validate API functionality
  • Use advanced QA testing tools to automate the API testing process

4. How do you measure the effectiveness of your testing efforts?

As you apply for the more senior positions, you will get asked more quality assurance interview questions about the results of the cases you worked on. These questions require a mix of practical experience and theoretical knowledge. 

Answer: Several QA metrics allow you to measure the effectiveness of your testing results: 

  • Defect detection rate: This metric is crucial because it compares the number of defects you can find during the testing to the ones found in the production stage. Higher detection indicates higher coverage and diligent execution of the test.
  • Test coverage: It measures the percentage of the code or functionality you have tested. The higher coverage you have, the lower chance of facing unexpected bugs that are really expensive to fix in production.
  • Test case efficiency: This metric focuses on the ratio of successful tests to the total runs. High efficiency means you have well-designed and well-executed test cases. 
  • Customer satisfaction: No matter what service or product you offer, customer satisfaction is a metric that should be among the most crucial to measuring your effectiveness, and testing processes are no exception. Although poor customer satisfaction does not necessarily indicate poor QA, higher customer satisfaction definitely shows that the software’s performance is good. That certainly means good QA.

40. How do you determine the test coverage in a complex software system, and what factors do you consider when assessing it?

Answer: Determining test coverage in a complex software system needs a complex approach. Firstly, I carefully analyse the project’s requirements and specifications, identifying critical functionalities, business workflows, and potential risk areas. Secondly, I categorise test coverage into various dimensions: functional, non-functional, code coverage, and risk-based coverage. Each dimension focuses on different aspects, ensuring a holistic approach to testing. Thirdly, I consider factors such as business impact, customer usage patterns, historical defect data, and regulatory compliance to prioritise testing efforts. I employ techniques like equivalence partitioning and boundary value analysis to maximise coverage while minimising redundant test cases. Continuous evaluation and adaptation of test coverage based on evolving project needs and feedback ensure comprehensive coverage in the dynamic software development landscape.
