Interview Questions 152

What is Functional testing?It is a test to check whether each and every function of that application is working as per the requirement (remember this work “as per requirement document”-you must say this in the interview). It is a major test where 80% of the tests are done. In this test, the Test Cases are executed (or run).

What is Integration testing?It is a test to check whether all the modules are combined together or not and working successfully as specified in the requirement document. (Just for your information: Each developer works on different modules. When they finish their code, the configuration management team puts them together and prepares a build. We, as testers, need to make sure that these modules, which are now combined, work as per requirement document)

What is Regression testing?When a new functionality is added to the software, we need to make sure that the added new functionality does not break the other parts of the application. Or when defects (bugs) are fixed, we need to make sure that the bug fix has not broken the other parts of the application. To test this, we perform. a repetitive test, which is called regression test.
