=== Test fixture ===

A [[test fixture]] (also known as a test context) provides the environment for each test case of a suite. Generally, a fixture is configured to setup a known, good, [[Runtime (program lifecycle phase)|runtime]] environment before tests run, and to cleanup the environment after.

The fixture is configured with one or more functions that setup and cleanup state. The test runner runs each setup function before each case and runs each cleanup function after.
