functional testing interview questions and answers

functionality is not working on What to do when most important the date of release?

If the release will be major, It should be rollback. Tester should create a bug for the issue.
If already fixed on previous release, we should reopen the bug. If the release is minor

In Fish model every stage is tested by other team for completeness and correctness.

In V model every stage same person reviews but in last stage software testing will be done by other testers.

4. S...
Are both 'Bakward Testing' & 'Regression Testing' one and the same? If Not, What is the difference between them?
Backward testing is retesting a specific module or area by seeing the defect or
bug which has raised in those perticular modules.
 or
I'm guessing you mean backward compatibility testing?? Given multiple version releases,
an application created on a new version should still work with the older versions making
it backwards compatibl...

a business perspective.

or
Main focus of Acceptance testing to see whether all the given requirement is implemented in
application or not as well as to find the defect

How do you test when No time?

There is a new build and you have not much time left behind to test(manual test), what will you do?

It is too late but still we cant perform adhoc testing when time is less, as it requires different
approaches for testing the application to find bug, to increase the bug count. So for testing an appl..

If there no sufficient time to test the application then immediately we will go for exploratory testing...

Exploratory testing is dynamic testing type and it tests the entire application simultaneously
while creating test design and test execution is possible.

What is the difference between Agile methodology and Waterfall model?

In Agile methodologies accepts "Dynamic changes". Agile is modern methodology where a 5 to 10 people gathered at one place and to deliver a working software with in a given short span of time i.e, 2 ...

What is the difference between smoke and sanity testcase?

Smoke testing is a black box testing technique and it test after immediate the build release.

Smoke test touches all the areas of the application functionality with out going into deep.

Smoke test reveals that any simple failure in the application and application is ready for further testing.

or

Smoke testing is a shallow and wide approach whereby all areas of the application without getting into too deep, is tested.
