An approach to integration testing where the lowest level components are tested first, then used to facilitate the testing of higher level components. The process is repeated until the component at the top of the hierarchy is tested.

 Test which focus on the boundary or limit conditions of the software being tested. (Some of these tests are stress tests).

 A fault in a program which causes the program to perform in an unintended or unanticipated manner.

 BVA is similar to Equivalence Partitioning but focuses on "corner cases" or values that are usually out of range as defined by the specification. his means that if a function expects all values in range of negative 100 to positive 1000, test inputs would include negative 101 and positive 1001.

 Testing in which all branches in the program source code are tested at least once.

 A test suite that exercises the full functionality of a product but does not test features in detail.

 The Capability Maturity Model for Software (CMM or SW-CMM) is a model for judging the maturity of the software processes of an organization and for identifying the key practices that are required to increase the maturity of these processes.

 A test tool that records test input as it is sent to the software under test. The input cases stored can then be used to reproduce the test at a later time. Most commonly applied to GUI test tools.
