Test fixture

A test fixture is something used to consistently test some item, device, or piece of software. Test fixtures can be found when testing electronics, software and physical devices.

Test fixtures can be found when testing electronics, software and physical devices. In testing electronic equipment such as circuit boards, electronic components, and chips, a test fixture is a device or setup designed to hold the device under test in place and allow it to be tested by being subjected to controlled electronic test signals. Examples are a bed of nails tester or SmartFixture. A software test fixture sets up the system for the testing process by providing it with all the necessary code to initialize it, thereby satisfying whatever preconditions there may be. An example could be loading up a database with known parameters from a customer site before running your test. The Ruby on Rails web framework uses YAML to initialize a database before running a test. This allows for tests to be repeatable, which is one of the key features of an effective test framework.
