Integration testing is the phase in software testing in which individual software modules are combined and tested as a group. No mocks or stubs are required; everything is tested as in production.
Integration testing is the phase in software testing in which individual software modules are combined and tested as a group. It occurs after unit testing and before system testing. 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 to those aggregates, and delivers as its output the integrated system ready for system testing.
No mocking or stubs are required; everything should be as in production.
