'test-framework-th' contains two interesting functions: 'defaultMainGenerator' and 'testGroupGenerator'.
'defaultMainGenerator' will extract all functions beginning with case_, prop_ or test_in the module and put them in a testGroup.

is the same as

'testGroupGenerator' is like 'defaultMainGenerator' but without 'defaultMain'. It is useful if you need a function for the testgroup (e.g. if you want to be able to call the testgroup from another module).
