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 quality assurance. It is the primary responsibility of the testing team to implement quality control.

Testing is the process of finding defects/bugs. 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 the testing teams work as a quality gatekeeper.

102). When do you think QA activities should start?

Ans:- This is how you should answer these types of QA lead interview questions.  QA activity should start at the beginning of the project. The more early it starts the more beneficial it is to set the standard for achieving quality. The cost, time, and efforts are very challenging in case the QA activities get delayed.

103). What is the difference between the Test Plan and Test Strategy?

105). How do you define the format of writing a good test case?

Ans:- The format of Test Case includes:

• Test case ID
• Test case description
• Severity
• Priority
• Environment
• Build version
• Steps to execute
• Expected results
• Actual results

106). What is a good test case?

Ans:- This is how you should answer these types of QA lead interview questions. In simple words, a good test case is one that finds a defect. But all test cases will not find defects, so a good test case can also be one that has all the prescribed details and coverage.

107). What would you do if you have a large suite to execute in very less time?

Ans:- In case we have less time and have to execute a larger volume of test cases, we should prioritize the test case and execute the high priority test cases first and then move on to the lower priority ones.

This way we can make sure that the important aspects of the software are tested.

Alternatively, we may also seek customer preference that which is the most important function of the software according to them, and we should start testing from those areas and then gradually move to those areas which are of less importance.

108). Do you think QAs can also participate to resolve production issues?

Ans:- Definitely!! It would be a good learning curve for QA to participate in resolving production issues. Many times production issues could be resolved by clearing the logs or making some registry settings or by restarting the services.

These kinds of environmental issues could be very well fixed by the QA team.

Also, if QA has an insight into resolving the production issues, they may include them while writing the test cases, and this way they can contribute to improving quality and try to minimize the production defects.

109). Suppose you find a bug in production, how would you make sure that the same bug is not introduced again?

Ans:- The 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, we can think of alternate test cases or similar kinds of test cases and include them in our planned execution.

110). What is the difference between Functional and Non-functional testing?

Ans:- Functional testing 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 requirements. We validate the test cases against the specified requirement and make the test results as pass or fail accordingly.

Examples include regression, integration, system, smoke, etc

Nonfunctional testing, on the other hand, tests the non-functional aspect of the application. It does not focus on the requirement, but on 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 tests are also given sufficient time and priority.

111) What is Negative testing? How is it different from Positive testing?

Ans:- Here is the answer to one of the frequently-asked QA interview questions. Negative testing is a technique that validates that the system behaves gracefully in case of any invalid inputs. For example, in case the user enters any invalid data in a text box, the system should display a proper message instead of the technical message that the user does not understand.

Negative testing is different from positive testing in 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.

112) How would you ensure that your testing is complete and has good coverage?

Ans:- Requirement Traceability Matrix and Test coverage metrics will help us to determine that our test cases have good coverage.

The requirement traceability matrix will help us to determine that the test conditions are enough so that all the requirements are covered. Coverage matrices will help us to determine that the test cases are enough to satisfy all the identified test conditions in RTM.

113) What are the different artifacts you refer to when you write the test cases?

Ans:- The main artifacts used are:

• Functional requirement specification
• Requirement understanding document
• Use Cases
• Wireframes
• User Stories
• Acceptance criteria
• Many a time UAT test cases

114). Have you ever managed to write the test cases without having any documents?

Ans:- Yes, there are cases when we have a situation where we have to write test cases without having any concrete documents.

In that case, the best way is to:

• Collaborate with the BA and development team.
• Dig into emails that have some information.
• Dig into older test cases/regression suite
• If the feature is new, try to read the wiki pages or help of the application to have an idea
• Sit with the developer and try to understand the changes being made.
• Based on your understanding, identify the test condition and send it to BA or stakeholders to review them.

116). What are the different verification techniques you know?

Ans:- Verification techniques are static. There are 3 verification techniques.

These are explained as follows:

(i) Review – This is a method by which the code/test cases are examined by an individual other than the author who has produced it. It is one of the easy and best ways to ensure coverage and quality.

(ii) Inspection – This is a technical and disciplined way to examine and correct the defects in the test artifact or code. Because it is disciplined, it has various roles:

• Moderator – Facilitates the entire inspection meeting.
• Recorder – Records the minutes of the meeting, defects that occurred, and other points discussed.
• Reader – Read out the document/code. The leader also leads the entire inspection meeting.
• Producer – The author. They are ultimately responsible to update their document/code as per the comments.
• Reviewer – All the team members can be considered a reviewer. This role can also be played by some group of experts if the project demands it.

(iii) Walkthrough – This is a process in which the author of the document/code reads the content and gets the feedback. This is mostly a kind of FYI (For Your Information) session rather than seeking corrections.

117). What is the difference between Load and Stress testing?

Ans:- Stress Testing is a technique that validates the behavior of the system when it executes under stress. To explain, we reduce the resources and check the behavior of the system. We first understand the upper limit of the system and gradually reduce the resources and check the system behavior.

In Load testing, we validate the system behavior under the expected load. The load can be of concurrent users or resources accessing the system at the same time.

118). In case you have any doubts regarding your project, how do you approach it?

Ans:- In case of any doubts, first, try to get it cleared by reading the available artifacts/application help. In case of doubts that persist, ask an immediate supervisor or the senior member of your team.

Business Analysts can also be a good choice to ask doubts. We can also convey our queries to the development team in case of any other doubts. The last option would be to follow up with the manager and finally with the stakeholders.

119). Have you used any Automation tools?

Ans:- The answer to this question is very much exclusive to the individual. Reply to all the tools and strategies of automation that you have used in your project.

120). How do you determine which piece of software requires how much testing?

Ans:- 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 everyone?
• Is the feature/program reliable enough?

121). Explain the difference between volume testing, load testing, and stress testing.

Ans:- Load testing is when you test the software under a heavier load that is still in the expected range, whereas stress testing is when you test the software under a much heavier load that goes outside the expected range. Volume testing is a system check to find out if the software can manage the expected data or requests

122). What are the steps of an automation test plan?

Ans:- Here is the answer to one of the frequently-asked QA interview questions. When completing an automation test plan, I review the company’s strategy to ensure I follow their guidelines. Typically, I record the scenario while incorporating an error handler. I then debug the script and fix the issues as needed, rerun the script and track the results of the fix.

123). How would you manage a testing issue?

Ans:- I first rerun the test to ensure it was not just an error. If the problem persists, I try to restart the software and the testing environment. This can confirm if everything is working fine on the testing side. If the issue persists, I contact my supervisor for guidance.
