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

@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).
