FAQs on QA Engineering:

1. What is Quality Assurance (QA)? QA is a systematic process that ensures the quality and reliability of products by checking whether they meet specific requirements.
2. How does QA differ from Quality Control (QC)? While QA focuses on the process of creating a product to prevent defects, QC emphasizes inspecting the finished product to identify defects.
3. What is the significance of automated testing in QA? Automated testing offers speed, repeatability, and accuracy, making it essential for scenarios like regression testing where tests are frequently repeated.
4. Why is manual testing still important despite automation? Manual testing is crucial for exploratory, usability, and ad-hoc testing scenarios where human intuition and observation are vital.
5. What are the different types of testing in QA? There are various types, including functional, non-functional, manual, automated, white-box, black-box, and many more.
6. How does Agile methodology impact QA processes? In Agile, QA is integrated throughout the development process, promoting continuous integration and frequent testing.
7. Why is test documentation important? It provides a clear structure, ensures consistency, aids in knowledge transfer, and serves as evidence of testing for stakeholders.
8. What are test oracles in QA? Test oracles are mechanisms or principles used to determine whether a test has passed or failed.
9. How do QA engineers prioritize which tests to run? Test prioritization depends on factors like the criticality of functionalities, recent code changes, user feedback, and more.
10. What role do QA engineers play in the SDLC (Software Development Life Cycle)? QA engineers ensure quality at each phase of the SDLC, from requirement gathering to deployment, by identifying and addressing potential issues.
