Backus-Naur Form: A metalanguage used to formally describe the syntax of a language.

Basic Block: A sequence of one or more consecutive, executable statements containing no branches.

Basis Path Testing: A white box test case design technique that uses the algorithmic flow of the program to design tests.

Basis Set: The set of tests derived using basis path testing.

Baseline: The point at which some deliverable produced during the software engineering process is put under formal change control.

Benchmark Testing: Tests that use representative sets of programs and data designed to evaluate the performance of computer hardware and software in a given configuration.

Beta Testing: Testing of a rerelease of a software product conducted by customers.

Binary Portability Testing: Testing an executable application for portability across system platforms and environments, usually for conformation to an ABI specification.

Black Box Testing: Testing based on an analysis of the specification of a piece of software without reference to its internal workings. The goal is to test how well the component conforms to the published requirements for the component.

Bottom Up Testing: 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.

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

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

Boundary Value Analysis: 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.

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

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