Here are 25 interview questions that a QA Software Engineer fresher may be asked during a job interview: Remember, these are just some examples of questions that may be asked during a QA Software Engineer fresher interview. It’s important to prepare by researching the company and the role, practicing your responses to common questions, and being confident and professional during the interview. 1. What do you know about software testing? Software testing is the process of evaluating software products to ensure that they meet the requirements, specifications, and quality standards of the customer or end-user. It is a critical aspect of software development that involves identifying defects or bugs in the software and providing feedback to the development team to improve the product’s quality. Software testing can be done manually or through automation tools. It involves various types of testing, such as functional testing, performance testing, security testing, and usability testing, among others. The goal of software testing is to identify and fix any issues before the software is released to the end-users, ensuring that the product is reliable, efficient, and user-friendly. 2. What are some of the software testing methodologies? There are several software testing methodologies, including: Each methodology has its advantages and disadvantages, and the choice of methodology depends on the project’s requirements and constraints. 3. What is the difference between verification and validation? Verification and validation are two terms used in software testing to ensure the quality of a product. Here are their definitions and differences: In summary, verification is focused on checking whether the product is being built correctly, while validation is focused on checking whether the right product is being built. Both verification and validation are important aspects of software testing and are typically performed throughout the software development life cycle. 4. What is the difference between black box and white box testing? Black box testing and white box testing are two methods of software testing that differ in the level of access to the internal workings of the software being tested. Here are their definitions and differences: In summary, black box testing focuses on the software’s external behavior and functionality, while white box testing focuses on the software’s internal workings and implementation. Both methods are important in software testing and are often used together to ensure comprehensive testing of the software. 5. What are the different levels of testing? There are typically four levels of testing that are performed in software testing, each with a different objective and focus. They are: Other types of testing, such as regression testing, performance testing, and security testing, are also performed at various levels of testing to ensure comprehensive testing of the software. 6. How would you prioritize test cases? Prioritizing test cases is an important aspect of software testing, as it helps to ensure that the most critical and high-risk areas of the software are thoroughly tested. Here are some steps that can be followed to prioritize test cases: By following these steps, test cases can be prioritized based on their importance, risk, and impact on the software, which can help to ensure comprehensive testing of the system. 7. What is regression testing? Regression testing is the process of retesting the software after changes or modifications have been made to it to ensure that no new defects or issues have been introduced. The purpose of regression testing is to verify that the changes made to the software have not affected its existing functionality, and that it continues to work as expected. Regression testing is typically performed as part of the software development life cycle, and it can be performed at any level of testing. It is important to perform regression testing because changes made to one part of the software can have unintended consequences on other parts of the system. Regression testing ensures that any unintended side-effects of changes made to the software are identified and fixed before they can cause issues in the production environment. Regression testing can be performed manually or through automation, depending on the complexity of the software and the size of the regression test suite. The regression test suite typically includes a set of test cases that cover the most critical and high-risk areas of the software. 8. What are some common software defects? Here are some common software defects that are often found during software testing: By identifying and addressing these common software defects, software testing can help to improve the quality and reliability of the software. 9. How do you track and manage defects? Tracking and managing defects is an important part of software testing, as it helps to ensure that defects are identified, reported, and resolved in a timely manner. Here are some steps that can be followed to track and manage defects: By following these steps, defects can be tracked and managed effectively, which can help to ensure that the software is of high quality and meets the expectations of the end users. 10. What is a test plan, and why is it important? A test plan is a document that outlines the approach, objectives, scope, and schedule of testing activities for a software project. It serves as a roadmap for the testing team, providing guidance on how to conduct testing and what needs to be tested. A test plan is important for several reasons: Overall, a well-written test plan is an essential part of the software testing process, as it provides a clear roadmap for testing activities and helps to ensure that testing is comprehensive, well-organized, and completed on time.
