Tests of ``subtrees'' of the total project hierarchy chart --- groups of subroutines calling each other. Integration Testing is generally a team responsibility.

An orderly progression of testing in which software elements, hardware elements or both are combined and tested until the entire system has been integrated.

Testing in which software components, hardware components, or both are combined and tested to evaluate the interaction between them.

A test that software modules work together as expected. JUnit was designed specifically for unit testing, but can be used in integration testing, as can JXCL. Unit tests focus on testing one class at a time; integration tests test interacting groups of classes.

A test that verifies an application works with other applications. One of three different tests that system developers perform during the implementation phase. 14.30 Intel, 4.10, 4.11, 4.13, 4.15
