method of TestCase · Added in 3.1 (source)

TestCase.addCleanup(function, /, *args, **kwargs)

Add a function, with arguments, to be called when the test is
completed. Functions added are called on a LIFO basis and are
called after tearDown on test failure or success.

Cleanup items are called even if setUp fails (unlike tearDown).
