Common (?) name for the top-level batch file that... * checks out the latest version of all the source * optionally calls 'make clean' to trash every scratch file * builds all the projects * runs all the ProgrammerTest''''''s * runs all the AcceptanceTest''''''s that passed in the last iteration Named to distinguish it from the suite of tests local to each module of a project. Those are the ones run between changes while adding features or refactoring in that module. See TestInfected, CodeUnitTestFirst, ThenDontCallMainLoop, GuiTesting, TestDrivenDesign, ContinuousIntegration, TestCollector. ST applies the principle ThreeStrikesAndYouAutomate to the act of integrating.
