122). State the difference between Quality Assurance, Quality Control, and Testing?

Ans:- 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 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 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.

123). 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. Explore and learn QA testing through JanBask Training's expertise.

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

Ans:- Test Strategy is at a higher level, mostly created by the Project Manager which demonstrates the overall approach of the testing for the entire project, whereas the Test plan depicts how the testing should be performed for a particular application, falling under a project.

125). Can you explain the Software Testing Life Cycle?

Ans:- Software Testing Life Cycle refers to a testing process that has specific steps to be executed in a definite sequence to ensure that the quality goals have been met.

126). 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

127). 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.

128). 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.

129). 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.

130). 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.

131). 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.

132) 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.

133) 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.

134) 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

135). 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.

136). 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.

137). 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.

138). 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.

139). 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.

140). 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?

141). 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

142). 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.

143). 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.

These were the top testing questions and answers, hopefully you found it helpful. Before we wrap up this post, let’s go through this quick guide on how to prepare to crack your QA testing interview and answers all the QA testing interview questions smartly.

144). How do you test a product when the requirements are still evolving?

Ans:- When formulating your answer to this QA interview question, consider presenting it in this manner: In such dynamic situations, adopting an agile development methodology, like Scrum, proves effective.

The process typically involves:

• Requirements Gathering Meetings: Engage with stakeholders to comprehend the product's purpose and desired outcomes.

• Prioritization and Sprint Assignments: Prioritize user stories and assign them to sprints for development.
• Continuous Testing: Employ various testing techniques, including unit tests, integration tests, user acceptance tests, and system testing, throughout the project's progression.
• Adaptability to Requirement Changes: Update tests continuously as requirements evolve to ensure the product aligns with the desired outcomes.

145). When do you consider choosing automated testing over manual testing?

Ans:- Several scenarios make automated testing a preferable choice:

• Repetitive Steps: Automated testing is advantageous when a test involves repetitive steps or requires multiple iterations.
• Large Data Handling: Automated testing excels at swiftly handling large amounts of data input into the tested system.
• Multiple Environments: Automated testing easily adapts to various environments, testing systems across multiple operating systems, browsers, and devices.
• Precise Timing: Automated tests can be precisely programmed to ensure each test step occurs at the exact time needed.
• Multiple Users: Automated testing can simulate multiple users accessing the system concurrently, allowing for more realistic testing.

146). What's the difference between smoke testing and sanity testing?

Ans:- To navigate this QA interview question successfully, consider outlining your response as follows:

Smoke Testing: Think of it as a quick check to make sure the critical parts of the software are working okay. It helps decide if the software is ready for more detailed testing.

Sanity Testing: This is like a focused check to see if recent changes to the code didn't mess up anything. It's all about making sure the existing features still work after updates, checking if previous bugs got fixed, and ensuring no new issues popped up.

147). What's the key principle of test-driven development (TDD)?

Ans:- In TDD, the main idea is to write automated tests before diving into writing the actual code. The key principle is to create small, specific tests that describe how the code should behave, and then write the code to fulfill those test requirements.

This approach ensures the code is well-crafted, easy to maintain, and aligns with business or user needs. TDD also speeds up feedback and lowers the chances of introducing bugs into the codebase.

148). Could you share a challenging defect you dealt with in a past project? 

Ans:- Addressing this QA interview question can be streamlined by structuring your answer as follows:

Here’s a structured way to provide a detailed response:

• Step 1: Give a thorough description of the defect, mentioning how you discovered it, whether through testing or customer feedback.
• Step 2: Explain why this particular defect was a tough nut to crack.
• Step 3: Outline the steps you took to fix the defect, highlighting any collaboration with developers or team members.
• Step 4: Talk about any obstacles you faced during the resolution process.
• Step 5: Detail how you made sure the defect was truly resolved and share the impact it had on the project and stakeholders.
• Step 6: Reflect on the lessons learned from this experience.

149). Can you share your experience with implementing an automation testing tool? 

Ans:- You can go through this automation testing tutorial to curate your response in detail:

Identifying Areas for Automation: Recognize parts of testing suitable for automation and prioritize them based on their impact.

1. Selecting the Right Tool: Evaluate and choose the automation testing tool that aligns with technical requirements.
2. Defining KPIs and Success Criteria: Clearly define Key Performance Indicators (KPIs) and success criteria for automation testing. Set up continuous monitoring and reporting mechanisms.
3. Team Training and Governance: Train the testing team on the automation tool, test plan, and establish necessary governance, policies, and procedures.
4. Tracking Effectiveness: Keep a close eye on the effectiveness of the automation testing tool and make adjustments as needed.

150). What is GUI testing?

Ans:- GUI (Graphical User Interface) testing is a method in software testing that zeroes in on assessing the visual and interactive components of a software application. The aim is to ensure that user interface elements, such as buttons, menus, forms, and windows, operate correctly and appear as intended. 

GUI testing verifies that user interactions are smooth, intuitive, and in line with design specifications. Testers scrutinize aspects like layout, font, color schemes, responsiveness, and the alignment of graphical elements. 

This form of testing is crucial for ensuring a positive user experience and catching any disparities between the intended design and how the application actually looks and behaves. By addressing issues early in the development cycle, GUI testing plays a pivotal role in enhancing usability, user satisfaction, and the overall quality of the software product.

151). Define two main types of acceptance testing

Ans:- When preparing to answer this QA interview question, consider presenting your response in this structured manner:

There are two main types of acceptance testing:

• User Acceptance Testing (UAT): This involves end-users or stakeholders conducting tests to ensure the software meets their needs. UAT confirms that the software is user-friendly, integrates smoothly into users’ workflows, and delivers the required functionalities.
• Business Acceptance Testing (BAT): BAT focuses on validating that the software aligns with the business objectives and goals. It ensures the software supports the organization's strategic goals and intended business processes.

Acceptance testing serves as the final checkpoint before software release. Successful completion indicates the software is ready for deployment to a broader audience. Any issues identified during acceptance testing are addressed, and once the software passes this phase, it signifies it meets the required quality standards and is accepted for production use
