Top 20 Manual Testing Interview Questions and Answers in 2022

In today’s competitive digital market, software testing plays an indispensable role in delivering error-free products to the end-users by catering to all their requirements. Manual testing has gained huge attention as it promises thorough end-to-end testing by checking all possible scenarios. This article will cover the important questions to help testers equip their knowledge base on the platform.

Manual Testing Interview Questions and Answers: 

  1. What is the difference between Quality Assurance and Quality Control? Quality assurance is a process-based approach that ensures all the requirements in the SRS are fulfilled. It verifies whether all the processes are followed to ensure quality deliverables on time.
    Quality control is a product-based approach to make sure the desired software complies with all the requirements given by the stakeholders.
  2. Define Software Testing Software testing is a detailed procedure that covers mismatch in the developed software from the actual SRS document and spotting the bugs in the application.
  3. Explain the two categories of software testing. Manual testing deals with the execution of test cases line by line to check the behaviour of the application by ensuring both actual and expected results are met. Automation testing is a process that makes use of scripts and tools to run the test cases by setting predefined parameters.
  4. List the different types of manual testing. There are six types of manual testing.
    1. Black box testing is external testing that validates the working of the system.
    2. White box testing is internal testing that verifies internal applications.
    3. Unit testing involves testing the modules separately for accuracy.
    4. System testing involves testing the product thoroughly from the scratch.
    5. Integration testing involves testing all modules together to see if they are working fine together.
    6. Acceptance testing is the verification of the software product against the given requirements.
  5. State the importance of documentation in the manual testing process. Documentation plays a significant role in the successful delivery of a product to the end customer. The test case document gives an idea for the developers to estimate the testing time for the application to help in quality deliverables.
  6. List the phases covered in Software Testing Life Cycle. 
    1. Requirement Analysis.
    2. Test Planning.
    3. Test Case Development.
    4. Test Environment Setup.
    5. Test Execution.
    6. Test Cycle Closure.
  7. Explain the difference between alpha and beta testing. Alpha testing is a type of UAT wherein software testing is done to find out errors before releasing the product to the users.
    Beta testing is also a UAT testing but carried out at the deployment site by covering all the changes requested by the client.
  8. What is a test bed in manual testing?  A physical environment that covers all the hardware and software requirements to help in the software testing process.
  9. What are the steps involved in manual testing?
    1. Planning a test.
    2. Analysis of requirements.
    3. Test case creation and running.
    4. Filing the bugs.
    5. Tracking the bugs until closure.
  10. Under what scenarios is manual testing preferred over automation? For projects with short delivery timelines, manual testing has been opted because it runs through all the functionalities in the application quickly. Also, manual testing holds good for Usability projects as they test the application from a user perspective.
  11. What is a test case? A test case is a formal test document covering all inputs, outputs, test data, expected results, and actual results.
  12. Explain the difference between bug and defect. Bugs are mistakes in the application spotted by the testers while comparing them with the requirement document. A defect is a mismatch between actual and expected results spotted by the developer after the delivery to customers.
  13. What is the defect life cycle? A defect life cycle is a period from which the defect is reported until closure.
  14. List the cons of manual testing.
    1. Load and performance testing is not feasible with the manual process.
    2. Regression tests can be time consuming if done with manual resources.
    3. Manual testing is not reliable as it involves human errors.
  15. Define test closure. Test closure is a detailed summary document that covers a total number of test cases, no of cases run, no of bugs reported, no of bugs resolved, no bugs not resolved, and no bugs rejected.
  16. What is a critical bug? A critical bug is one that affects the key functionality of the application hindering the delivery of the product.
  17. Difference between positive and negative testing. Positive testing involves testing the application with only valid values entered by the tester. On the other hand, negative testing is breaking the application by inputting invalid test data to check its behaviour.
  18. Explain the difference between smoke and sanity testing. Smoke is a build verification test that ensures all the major functionalities in the released build are working fine. Sanity is thorough testing of all the internal modules to check all the functionalities are working fine.
  19. How do the test if requirements keep on changing? The tester needs to skip the particular module if requirements are unclear and mark it as not tested during delivery to the client for clarity.
  20. What are mandatory skills for a qualified tester?
    1. Ability to work under tight deadlines.
    2. Very good interpersonal skills.
    3. Problem-solving
    4. To work unitedly with the team with great involvement.
