Test Fixture

A test fixture is a device used to consistently test another device, item, or piece of software. Test fixtures are commonly used in electronics and other “high tech” industries.

In electronics, test fixtures are designed to hold the device under test in place while it is tested and subjected to controlled electronic test signals. Test fixtures are commonly used to test PCBs (printed circuit boards), electronic components, and chips.

For physical or mechanical testing, test fixtures hold or support the specimen during testing. Many written testing methods specifically detail the requirements of the test fixtures to be used. The potential influence of test fixtures on the resulting tests is the subject of much ongoing research.

In software testing, test fixtures set up the test itself by providing all the code needed to initialize the test. For example, loading a database with known parameters from a customer site prior to starting the test. Software test fixtures can be configured in three ways: in-line, where a developer creates the test fixture in the same way as the rest of the test; delegate, in which a developer creates the test fixture in a separate, standalone “helper method” that can be accessed by multiple test methods; and implicit, where a developer places the test fixture in a “setup method”, where it is used to set up multiple test methods.
