Developing custom test fixtures demands more engineering time as well as an in-depth knowledge of mechanical design, pcb test methods paired with precision machining. In addition to In-circuit testing, functional testing is widely used in the industry to verify electronic cards. Another bad practice is a test setup that contains more steps than needed for the test; this is a problem seen in in-line setup. Implicit setup places the test fixture in a setup method which is used to set up multiple test methods. It also causes the order of tests to be important: a modified fixture must be reset if more tests are to be run after an unsafe test.[1]. 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. In physical testing, a fixture is a device or apparatus to hold or support the test specimen during the test.
