Test Cases

A test case for unit-tests specifies

concrete steps which establish an initial state,

some invocations of query methods,

and the expected results.

Likewise, a test case for higher-order testing specifies

some input (or some actions on a graphical user interface),

and the desired outcome.

Test cases must be concrete and consequently specify concrete values. A test case is not sufficiently described if you tell ``something'' has to be passed to a method.

The point is that results of performed test cases must be reproducible.
