1)Can you explain the difference between verification and validation in software testing?
Verification: It involves checking whether a product meets specified requirements. It's about ensuring that the product is being developed according to the design specifications.
Validation: It involves evaluating a system during or at the end of the development process to determine whether it satisfies the specified requirements.
2)What is the difference between functional testing and non-functional testing?
Functional Testing: It involves testing the system against its functional requirements. Examples include unit testing, integration testing, and system testing.
Non-functional Testing: It involves testing the non-functional aspects of a system, such as performance, usability, security, etc. Examples include load testing, stress testing, and usability testing.
3)Explain the concept of test-driven development (TDD).
TDD is a software development approach where tests are written before the code is implemented. The development cycle follows the pattern of writing a test, implementing the code, and then refactoring.
4)What is regression testing, and why is it important?
Regression testing ensures that new changes to the codebase do not negatively impact existing functionality. It helps in detecting and fixing defects introduced during the development of new features or bug fixes.
5)How do you prioritize test cases?
Test case prioritization depends on factors like criticality of the functionality, risk assessment, and business impact. Critical and high-risk areas are often tested first.
6)What is the purpose of a test plan?
A test plan outlines the testing approach, resources, schedule, and deliverables for a testing project. It provides a roadmap for the testing process.
7)How do you handle a situation where there is not enough time for thorough testing?
Prioritize testing based on critical functionality and high-risk areas. Communicate the potential risks to stakeholders and document the testing performed along with any known limitations.
8)Explain the concept of test automation and its benefits.
Test automation involves using tools to execute test cases and compare the actual outcomes with expected outcomes. It helps in improving testing efficiency, repeatability, and coverage.
9)Can you describe different types of testing tools you have used?
Mention any test management tools, automation tools, performance testing tools, etc., that you have experience with. Provide examples of how you utilized these tools in previous projects.
10)How do you stay updated with the latest trends and advancements in software testing?
Discuss your participation in conferences, online forums, reading industry blogs, and any relevant certifications you may have pursued.
