Integration testing finds the bugs that occur when two or more models integrated. Main purpose of Integration testing is to identifying the functional, requirement and performance level bugs. When modules not integrated, they perform as per requirement but when they integrated, functional, requirement and performance related issues will occurs due to the integration.

2. Top down
In Top down Integration testing approach, all Top level integrated modules are tested first and its sub modules tested from top to down step by step.

  5. Hi Guys,

    Last week I attended an Interview and the Interviewer asked me who does Integration Testing.
    I told it would be done by Developers after Unit Testing is done inorder to verify whether the functionality is working fine or not
    Then the build would come to Testers
    But he told me that it wont be done by developers
    Could anyone help me out
