The document provides a comprehensive overview of frequently asked QA interview questions and their answers, covering topics such as testing techniques, the differences between quality assurance, control, and testing, verification vs. validation, and strategies for approaching project doubts. It also emphasizes the importance of both functional and non-functional testing, as well as the role of QA in resolving production issues and preventing bugs from recurring. Additionally, it outlines various testing methodologies including load and stress testing, and elaborates on writing test cases without documentation.

We can know this factor by finding out the Cyclomatic Complexity. The technique helps to identify the below 3 questions for the programs / features •Is the feature / program testable? •Is the feature/ program understood by every one? •Is the feature / program reliable enough? As a QA we can use this technique to identify the “level” of our testing.

What is the difference between Quality Assurance, Quality Control and testing? Quality Assurance is the process of planning and defining the way of monitoring and implementing the quality (test) processes within a team and organization. This method basically defines and sets the quality standards of the projects. Quality Control is the process of finding defects and providing suggestions to improve the quality of the software. The methods used by Quality Control are usually established by the quality assurance. It is the primarily responsibility of the testing team to implement quality control. Testing is the process of finding defects / bug. It validates whether the software built by the development team meets the requirements set by the user and the standards set by the organization. Here the main focus is on finding bugs and testing team acts as quality gatekeeper.

In case of any doubts, first try to get it clear by reading the available artifacts / application help. In case of doubts still persisting, ask immediate supervisor or the senior member of your team. BA’s would also be a good choice to ask the doubts. We can also touch base with the development team in case of any doubts. The last option would be to follow up with the manager and finally to the stakeholders.

Stress Testing is a technique which validates the behaviour of the system when it executes under stress. To explain, we reduce the resources and check the behaviour of the system. We first understand the upper limit of the system and gradually reduce the resources and check the system behaviour. In Load testing we validate the system behaviour under the expected load. The load can be of concurrent user or resources accessing the system at the same time.

Verification techniques are static in nature. There are 3 verification techniques: Review, Inspection and walkthrough. 1. Review – Is a method by which the code / test cases are examined by the individual other than the author who has produced it. 2. Inspection – Is a technical and disciplined way to examine and correct the defects in the test artifact or code. Because it is disciplined. 3. Walkthrough – Is a process in which the author of the document / code reads the content and gets the feedback. This is most of the time a kind of FYI (For your information) session rather than seeking corrections.

Validation is the process of evaluating the final product to check whether the software meets the business needs. The test execution which we do in our day to day life are actually the validation activity which includes smoke testing, functional testing, regression testing, systems testing etc… Verification is a process of evaluating the intermediary work products of a software development lifecycle to check if we are in the right track of creating the final product.

Yes, many a time we have a situation where we have to write test cases without having any concrete documents. In that case, best way is to 1. Collaborate with the BA and development team. 2. Dig into mails which have some information. 3. Dig into older test cases / regression suite 4. If the feature is new, try to read the wiki pages or help of the application to have an idea 5. Sit with the developer and try to understand the changes being made. 6. Based on your understanding, identify the test condition and send it to BA or stakeholders to review them.

Negative testing is a technique which validates that the system behaves gracefully in case of any invalid inputs. For example, in case user enters any invalid data in a text box, system should display a proper message instead of technical message which the user does not understands. Negative testing is different from positive testing in a way that positive testing validates that our system works as expected and compares the test results with the expected results. ------------ Most of the time scenarios for negative testing are not mentioned in the functional requirement documents. As a QA we have to identify the negative scenarios and should have provisions to test those.

Functional testing basically deals with the functional aspect of the application. This technique tests that the system is behaving as per the requirement and specification. These are directly linked with customer requirement. We validate the test cases against the specified requirement and make the test pass or failed accordingly. “Examples include regression, integration, system, smoke etc…” Nonfunctional testing – on the other hand tests the Nonfunctional aspect of the application. It tests NOT the requirement, but the environmental factors like performance, load and stress. These are not explicitly specified in the requirement but are prescribed in the quality standards. So as QA we have to make sure that these testing are also given sufficient time and priority.

Suppose you find a bug in production, how would you make sure that the same bug is not introduced again? Best way is to immediately write a test case for the production defect and include it in the regression suite. This way we ensure that the bug does not get introduced again. Also many a time we can also think of alternate test cases or similar kind of test case and include them in our planned execution.

Definitely!! It would be a good learning curve for QA’s to participate in resolving production issues. Many a time production issues could be resolved by clearing the logs or making some registry settings or by restarting the services. These kind of environmental issues could be very well fixed by the QA team. Also If QAs have an insight on resolving the production issues, they may also include them while writing the test cases, and this way they can contribute to improve quality and try to minimize the production defects.
