QA Interview Questions with guided examples
Question 1: Describe the defect cycle steps
Ans: As a candidate, you should have knowledge of the bug cycle, which typically follows these steps:
Defect discovery: A defect is discovered during testing or by a customer.
Defect reporting: The tester reports the defect along with a detailed description and steps to reproduce it.
Defect prioritization: The defect is prioritized based on its severity and impact on the product.
Defect assignment: The defect is assigned to a developer to investigate and fix.
Defect fixing: The developer fixes the defect and verifies the fix.
Defect Validation: The tester validates that the defect has been fixed and closes it if it has.
Defect closure: The defect is closed after being fixed and validated.
Note — These are basic steps followed, I haven’t discussed the stages used in defect life cycle.
Question 2: Do you think QA’s can also participate in resolving production issues?
Ans: Yes, QA’s can and should participate in resolving production issues. Quality assurance professionals can bring a unique perspective to the problem-solving process as they deeply understand the system’s functionality and how it is expected to behave.
In addition, they are skilled at identifying and replicating bugs and defects, which can be invaluable in identifying the root cause of a production issue.
By collaborating with developers and other stakeholders, QA’s can help diagnose and resolve issues quickly, minimizing their impact on users and improving the system’s overall quality.
Question 3: What constitutes a good test case?
Ans: A test case can be considered as good if it is capable of finding defects and errors. Therefore, a test case that exhibits the following characteristics can be considered as a good one:
Accuracy- It must exact its purpose
Economic- It must not include unnecessary words or steps
Traceable- It should be traceable to the requirements
Repeatable- The test case must be usable again and again
Question 4: What are High-level and Low-level test cases?
Ans: High-level: The cases which cover all the core functionalities of a product are considered high-level test cases.
Low-level: The cases which are related to the UI of the application are considered low-level test cases.
Question 5: How will you determine when to stop testing?
Ans: It can be hard to know when to stop testing. Many modern software applications are so complicated and run in such a relaxed environment that thorough testing is impossible. The following are some regular criteria to consider when considering when to end testing:
Deadlines are very important (release deadlines, testing deadlines, etc.)
Completed test cases with a certain percentage of passing
When the test budget runs out
When the coverage of code, functionality, or requirements arrives at a certain point, it is said to be complete
When the bug rate drops below a specific threshold
When the beta or alpha testing stage is over
Note — Project may require testing to stop, but a product’s testing can never end!
Question 6: How to decide if a bug is severe enough to block a release?
Ans: Always try to give pointers for these type of questions and questions can help to decide:
1) Does this bug affect our critical functionality of the application?
2) Does this bug affect our new features?
3) Does this bug affect our new feature but still we can get correct information in some different way?
4) Is the bug found only specific for a particular workflow and works fine for others?
These are some practical questions which can be a deciding factor!
Moreover we can also answer using below pointers:
1) The impact of the bug on the functionality
2) The bug’s occurrence frequency
3) The bug’s effect on the end user’s experience
4) Reproducibility of the bug
5) Data loss or security vulnerabilities caused by the bug
6) Brand impact of the bug
Note — Bugs can sometimes be released even if they are of high priority because we can fix them with OTA updates in mobile apps or in WebApps with quick patches.
Bugs fixing and management is a really complex topic so it entirely depends upon team discussion. The points suggested by me are being used by me and my teams.
