Manual Testing Interview Question with Answer

1.Can u let me know the example of some defect that was identified in your project?
-Before that i found in payment option of menu items not showing recently updated payment.
-I also detected some specific windows are making delay in opening for intraday chart with smaller time frame.
2.What is severity?
A-Severity is the impact of defect on the customer business application.
2.1.High severity and high priority bug?
A-When a banking website is not showing the balance of an customer is an high priority and high severity bug.
2.2.High severity and low priority bug?
A-When we are generating the yearly statement of current year its showing error.
or Customer is not able to purchase product by using old browser.
2.3.Low severity and high priority bug?
A-Spelling mistake on home page
or Company logo is not displaying.
2.4 Different types of severity?
Critical-The defect affects critical functionality or critical data. It does not have a workaround. Example: Unsuccessful installation, complete failure of a feature.
Blocker-The defect affects major functionality or major data. It has a workaround but is not obvious and is difficult. Example: A feature is not functional from one module but the task is doable if 10 complicated indirect steps are followed in another module/s.
Minor: The defect affects minor functionality or non-critical data. It has an easy workaround. Example: A minor feature that is not functional in one module but the same task is easily doable from another module.
Trivial: The defect does not affect functionality or data. It does not even need a workaround. It does not impact productivity or efficiency. It is merely an inconvenience. Example: Petty layout discrepancies, spelling/grammatical errors.
2.4.Low severity and low priority?
A-Terms and condition page is taking too much time to loading.
3.Who sets the severity in your project?
A-This is set by project manager or product manager.
4.What is priority?
A-Priority is the measure of urgency attached to fixing a defect.
4.1.Different types of priority?

  • Priority 1 – Critical (P1): This has to be fixed immediately within 24 hours. This generally occurs in cases when an entire functionality is blocked and no testing can proceed as a result of this. Or in certain other cases if there are significant memory leaks, then generally the defect is classified as a priority -1 meaning the program/ feature is unusable in the current state.
  • Priority 2 – High (P2): Once the critical defects have been fixed, a defect having this priority is the next candidate which has to be fixed for any test activity to match the “exit” criteria. Normally when a feature is not usable as it’s supposed to be, due to a program defect, or that a new code has to be written or sometimes even because some environmental problem has to be handled through the code, a defect may qualify for a priority 2.
  • Priority 3 – Medium (P3): A defect with this priority must be in contention to be fixed as it could also deal with functionality issues which is not as per expectation. Sometimes even cosmetic errors such as expecting the right error message during the failure could qualify to be a priority 3 defect.
  • Priority 4 – Low (P4): A defect with low priority indicates that there is definitely an issue, but it doesn’t have to be fixed to match the “exit” criteria. However this must be fixed before the GA is done. Typically, some typing errors or even cosmetic errors as discussed previously could be categorized in here. Sometimes defects with priority low are also opened to suggest some enhancements in the existing design or a request to implement a small feature to enhance user experience.

5.Who sets the priority in your project.
A-Developer and Project Manger set priority.
6.What is SDLC?
A- A framework to define each and every steps to be carried out during a software development is called as SDLC?
7.What are the different types of SDLC model?
A-Water Fall
Hybrid(Spiral & Prototype)
(V & Prototype)
8.What are the advantages and disadvantages of SDLC model?
-Formal Review at end of the each stage is very suitable for managerial control.
-Throughout the life cycle it followed by systematic documentation.
-The complete cycle goes thorough intermediate stages that can be reviewed  to verify weather project is going as per the client needs  and requirement.If not they can modify the project as per their requirement at very  initial stage of project.
-Major problem can not identified from end user prospective unless until the product is fully developed.
-Major challenged can not properly specified in side SRS document as user expected.
-User can not immediate verify the intermediate products and give review this product is suitable for his requirement or not?
-Another disadvantage of a program or software that follows the SDLC program is it encourages stiff implementation instead of creativity. There are requirements that must be met and that is all that developers complete.
-It is difficult to write the documentation part a lots of efforts required to maintain correctly the documentation.
9.Can you explain the V model and Agalie model?

38.What is smoke testing?
A-We used to do smoke testing to ensure that whether the build is ready for testing or not.
39.When do we do smoke testing?
A-We used to do smoke test before any testing at first when a new build is lunched.
40.Why does the test engineer do smoke testing?
A-We used to do smoke test to ensure the current build is testable or not?
Smoke testing is conducted to ensure whether the most crucial functions of a program are working, but not bothering with finer details. (Such as build verification.
41.What is the difference between smoke and sanity testing?


  • Smoke testing originated in the hardware testing practice of turning on a new piece of hardware for the first time and considering it a success if it does not catch fire and smoke. In software industry, smoke testing is a shallow and wide approach whereby all areas of the application without getting into too deep, is tested.
  • A smoke test is scripted, either using a written set of tests or an automated test
  • A Smoke test is designed to touch every part of the application in a cursory way. It’s shallow and wide.
  • Smoke testing is conducted to ensure whether the most crucial functions of a program are working, but not bothering with finer details. (Such as build verification).
  • Smoke testing is normal health check up to a build of an application before taking it to testing in depth.


  • A sanity test is a narrow regression test that focuses on one or a few areas of functionality. Sanity testing is usually narrow and deep.
  • A sanity test is usually unscripted.
  • A Sanity test is used to determine a small section of the application is still working after a minor change.
  • Sanity testing is a cursory testing, it is performed whenever a cursory testing is sufficient to prove the application is functioning according to specifications. This level of testing is a subset of regression testing.
  • Sanity testing is to verify whether requirements are met or not, checking all features breadth-first.

42.Can u explain how how do you have done smoke testing in your current project?
43.What is ad-hoc testing?

A-The very term ad-hoc implies the lack of structure or something that is not methodical. When you talk about ad-hoc testing, it means that it is a form of black box or behavioral testing performed without any formal process in place.

The formal process here means having the documentation like requirement documents, test plan, test cases and proper test planning in terms of its schedule and order of performed tests. Also any actions performed during the testing are not typically documented.

strategy. Factors that are to be addressed in testing a specific application
system will form the test factor.
b) Test phase: The phase of the systems development life cycle in which testing
will occur.
