What might you include in a quality assurance testing document?

An interviewer asks this question to understand your experience with using testing documents. If you have worked as a QA engineer before, explain what you included in your testing document. When you have limited experience, it might be beneficial to understand what a general document should include.

Example: “Each QA job Ive had required different inclusions, so I would include whatever information was required by management. At my previous jobs, Ive included test plans, test cases, bug reports, user manuals, inspection reports, defects and requirements.”

How would you manage a testing issue?

This question attempts to uncover how you might handle problems during your testing. The interviewer might like to hear about how you manage issues with the software test itself. Explain to the interviewer what your general steps would include before asking your supervisor.

Example: “Depending on the issue, I would rerun my test to ensure the testing was being implemented correctly. If the problem persisted, I would restart the software and testing environment to make sure everything was working on the testing side. If problems persisted after a couple of minutes, I would talk to my supervisor or manager so I could manage my time wisely.”

What is the difference between verification and validation?

Verification and validation are two critical processes that quality assurance engineers use when testing software quality and performance. Consider providing a brief explanation of the two processes and how they relate to your tasks as a QA engineer.

Example: “Verification is the assurance process that occurs during the software development stage, whereas validation is the evaluation process that happens once the software is fully developed. I would use verification as my continuous testing throughout development and validation as my final tests to make sure the software runs as it should.”

Quality Assurance interview Questions and Answers for QA Engineers

1) What is the difference between the QA and software testing?

The role of QA (Quality Assurance) is to monitor the quality of the “process” used to produce the software. While the software testing, is the process of ensuring the functionality of final product meets the user’s requirement.

2) What is Testware?

Testware is test artifacts like test cases, test data, test plans needed to design and execute a test.

Build: It is a number given to Installable software that is given to the testing team by the development team.

Release: It is a number given to Installable software that is handed over to the customer by the tester or developer.

4) What are the automation challenges that SQA(Software Quality Assurance) team faces while testing?

  • Mastering the automation tool
  • Reusability of Automation script
  • Adaptability of test case for automation
  • Automating complex test cases.
  • 5) What is bug leakage and bug release?

    Bug release is when software or an application is handed over to the testing team knowing that the defect is present in a release. During this the priority and severity of bug is low, as bug can be removed before the final handover.

    Bug leakage is something, when the bug is discovered by the end users or customer, and not detected by the testing team while testing the software.

    6) What is data driven testing?

    Data driven testing is an automation testing framework, which tests the different input values on the AUT. These values are read directly from the data files. The data files may include csv files, excel files, data pools and many more.

    7) Explain the steps for Bug Cycle?

  • Once the bug is identified by the tester, it is assigned to the development manager in open status
  • If the bug is a valid defect the development team will fix it.
  • If it is not a valid defect, the defect will be ignored and marked as rejected
  • The next step will be to check whether it is in scope. If the bug is not the part of the current release then the defects are postponed
  • If the defect or bug is raised earlier then the tester will assign a DUPLICATE status
  • When bug is assigned to developer to fix, it will be given a IN-PROGRESS status
  • Once the defect is repaired, the status will change to FIXED at the end the tester will give CLOSED status if it passes the final test.
  • 8) What does the test strategy include?

  • 12) What is Agile testing and what is the importance of Agile testing?

    Agile testing is software testing, is testing using Agile Methodology. The importance of this testing is that, unlike normal testing process, this testing does not wait for the development team to complete the coding first and then doing testing. The coding and testing both goes simultaneously. It requires continuous customer interaction.

    13) What is Test case?

  • Load Testing: Testing an application under heavy but expected load is known as Load Testing. Here, the load refers to the large volume of users, messages, requests, data, etc.
  • Stress Testing: When the load placed on the system is raised or accelerated beyond the normal range then it is known as Stress Testing.
  • Volume Testing: The process of checking the system, whether the system can handle the required amounts of data, user requests, etc. is known as Volume Testing.
  • 18) What are the five common solutions for software developments problems?

  • Setting up the requirements criteria, the requirements of a software should be complete, clear and agreed by all
  • The next thing is the realistic schedule like time for planning , designing, testing, fixing bugs and re-testing

  • The stub is called from the software component to be tested. It is used in top down approach
  • The driver calls a component to be tested. It is used in bottom up approach
  • It is required when we need to test the interface between modules X and Y and we have developed only module X. So we cannot just test module X but if there is any dummy module we can use that dummy module to test module X
  • 26) Explain what is Bug triage?

  • 38) Mention how validation activities should be conducted?

    Validation activities should be conducted by following techniques

  • Hire third party independent verification and validation
  • Assign internal staff members that are not involved in validation and verification activities
  • Independent evaluation
  • Can you write test scripts? What testing software do you use?

    Selenium. IBM Functional Tester. TestComplete. Katalon Studio. Functionize (especially Functionize). Your interviewee’s familiarity with a brand of test software may be the difference between them getting the job at your company and getting the fabulous opportunity to work somewhere else.

    It’s fine if the job applicant knows more than one tool; if nothing else, it suggests they understand the pros and cons of each one. Even better: If the candidate lives and breathes the software your company uses, no one (especially not you) has to spend time training the newbie.Â

    Though a lack of familiarity should not be a reason to escort the person off the premises. Tools change; you probably aren’t using the same software you were five years ago. It’s useful if the candidate knows your current tools – but in the long run, it’s more important to find someone who loves to learn new things.
