DeprecationTestEngine()
Represents a TestEngine (id 'spek-deprecation') which uses the SpekTestEngine but allows to define tests which shall be converted to ForgivingTests.
Which tests shall be forgivable can be defined with the custom config property forgive and a regular expression
matches desired UniqueIds. For instance:
forgive=.*\.Iterable\..*
Turns all tests containing .Iterable. in their UniqueId into a ForgivingTest.
Moreover, the engine fails if no tests were discovered or if an error occurs during discovery.
