'''Integration testing''', also called '''integration and testing''' ('''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 testing|unit]] or [[system testing|system]] level.

Often, integration testing is conducted to evaluate the [[regulatory compliance|compliance]] of a component with [[functional requirement]]s.<ref>{{Cite book|title=ISO/IEC/IEEE International Standard - Systems and software engineering|publisher=ISO/IEC/IEEE 24765:2010(E)|year=2010|pages=vol., no., pp.1–418, 15 Dec. 2010}}</ref> 

In a structured development process, integration testing takes as its input [[module (programming)|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.<ref>[https://books.google.com/books?id=utFCImZOTEIC&dq=integration+test&pg=PA73 Martyn A Ould & Charles Unwin (ed), ''Testing in Software Development'', BCS (1986), p71].
