10 Must-Know Software Testing Interview Questions
These general questions permit you to demonstrate what you know. However, you need to be careful and elaborate your answer; this is not just about one kind of knowledge or the other, but how you combined the two to come up with a solution. Showing real examples from your work is a big plus How are verification and validation different from each other? While verification is done to prove that software artifacts like code or test cases are as per specifications, it is considered to be building the product right. Validation is meant to confirm that software meets user demands: building the right product. Verification checks specs against design, whereas validation takes care of real-world scenarios, such as transaction processes carried out by a banking app. What are the levels of software testing? Unit Testing: Testing of individual components for accuracy. Integration Testing: Checking if the components work well together. System Testing: Testing of the complete system as a whole. Acceptance Testing: Testing of the system with regards to real-world application. Other types of testing include regression testing which prevents any fix from damaging existing functionality; performance testing assesses scalability; security testing checks vulnerabilities. Functional testing vs. Non-Functional Testing Functional testing verifies whether the application is working per requirements, for example, verifying whether various login methods work as intended. Non-functional testing is focused on performance, usability, security, compatibility, and reliability, among other attributes, which led to the product being verified to provide user satisfaction and to be robust. How would you prioritize test cases? Prioritization can be based on risk factors, dependencies, and overall business impact—fully utilizing risk zones and the application's critical functionality. The other contribution related to either case would be narrated by providing some of the examples validating your critical thoughts. What is Test-Driven Development? TDD allows writing test cases before coding the application itself. It goes through iterations of Red-Green-Refactor; the cycle can be summarized like the following: Write a test case that fails (Red). Write a piece of code that will make the test case pass (Green). Refactor the code. This iterative technique promises that only high-quality, maintainable code has been developed. What do you understand from regression testing? Regression testing is used for verifying whether updates to the software have not caused any new bugs. This can be followed through using Automated tools, and maintaining the regression test suite allows for foolproof regression testing. Black-box versus white-box testing Black-box testing means testing functionalities without having knowledge about the internal code logic. It is best for testing user experience. White-box testing means looking into internal code structure to check code quality and code coverage. What would you do with defects? Capture, log, and prioritize defects using any bug-tracking mechanisms. Coordinate with developers for defect resolution, providing documentation for reproducibility. What is test coverage? Test coverage measures the quantity of testing done over application. The coverage includes functional coverage as well as code coverage. Comprehensiveness of test coverage showcases that untested areas or scenarios need to be additionally handled along with maintaining a traceability matrix. How do you stay informed? Keep up with industry updates by attending conferences, participating in forum discussions, and absorbing related literature. Continuous learning is key to success in software testing.
