Ask someone from another language how they count their
tests classes. In Smalltalk you can easily:
TestCase allSubclasses size
or write other nice statistics scripts about your programs.
Reflection can be used to find an appropriate selector when you
know the input and the result. I'm sure you know that features available in
the finder tool: 3. 4. 7.
or according examples from the finder tool like:
MethodFinder methodFor: #( (4 3) 7 (0 5) 5 (5 5) 10).
Maybe the PragmaCollector is also a nice example: just define a method
(PragmaCollector filter: [:pragma | #todo = pragma keyword]) reset collected
Also have a look at "Teachable" from config browser. It's not directly related
to reflection but shows how easy it is to use #doesNotUnderstand and write
mocks. One can do other nice tricks - like implement a getter automagically when it
is not there, ...
Beware - you already know the "true become: false" trick ;)
