Integration testing, also called integration and testing, abbreviated I&T, is a form of software testing in which multiple parts of a software system are tested as a group.

Integration testing describes tests that are run at the integration-level to contrast testing at the unit or system level.

Often, integration testing is conducted to evaluate the compliance of a component with functional requirements.[1]

In a structured development process, integration testing takes as its input modules that have been unit tested, groups them in larger aggregates, applies tests defined in an integration test plan, and delivers as output test results as a step leading to system testing.[2]
