At the same time, a release is defined as the number given to the installable software or executable software which is given to the customer by the developer or tester.
Q2. Explain the life cycle of a Bug or Bug cycle?
The steps of a Bug cycle are defined as below:

Let us move to the next QA Interview Questions.
Q8. Define test stub and test driver?
The test stub will be a call from the software component to be tested and works in a top-down approach.
The test driver will call a component to be tested and works in a bottom-up approach.
Q9. How should validation activities be conducted?
This is the most asked QA Interview Question in an interview. Validation activities can be conducted by hiring third-party validation engineers for verification and validation, internal team members who are not involved in validation activities, and Independent evaluation of a product like customers.
Q10. What are the different testing levels while testing any product?
There are four types of testing levels while testing any product as follows:
- Component level testing
- System-level testing
- Integration testing: checks the interaction between the modules
- Acceptance testing: Here, the customer or user expects the desired output for the given input.
I hope you will have a good understanding of these concepts, and I suggest you go through your projects, what are your role in the project, and the testing process followed in your company. It will be helpful for the QA interview, and I wish you all good luck with your Interview.
