SUT at XUnitPatterns.com (original) (raw)

Also known as: AUT, MUT, CUT

The "system under test". It is short for "whatever thing we are testing" and is always defined from the perspective of the test. When we are writing [unit tests](unit test.html) the system under test (SUT) is whatever class (a.k.a. CUT), object (a.k.a. OUT) or method(s) (a.k.a. MUT) we are testing; when we are writing [customer tests](customer test.html), the SUT is probably the entire application (a.k.a. AUT) or at least a major subsystem of it. The parts of the application that we are not verifying in this particular test may still be involved as a depended-on component (DOC).
