This is a stub for Hardware Testing electrical circuits or devices

There are two ideal methods White box testing and Black Box testing. And a non-idealized Gray box testing.

Some white box methods include In circuit test (ICT), Automated optical inspection (AOI). Circuit changes or devices changes affect these test, requiring updates or new fixtures.

An example black box method is Functional test. As long as the design remains true to it functional specification circuit or device changes do not affect the test.

Finlay gray box testing is a combination of both methods. Functional interfaces are specified and tested for user required characteristics, and some internal non-user accessible circuits are interfaced and tested. This test method allows modifying some areas of the design without affecting the test.
