This was not my implementation.

Mine is (the latest was):
https://github.com/Deganius/gb.deg.unittest/tree/develop

There test methods are combined to a "test suite" and can be executed
independent from each other in random order.

The test methods are in Testclasses, which are identified by inheriting
from UnitTest and the names of the testmethods inside start with "Test".

Yes, I tried to discuss that as I wrote about fixtures. What I find
interesting with TAP is the standardized output format.

But I also would prefer the execution of single testmethods independent
from each other.

I startet with the fork of ComUnit which was a fork of JUnit for VB6.

Maybe we could combine the two approaches, the one from Tobi which is
the actual gb.test (which is a complete rewrite in honour of TAP, my
code is completely gone) and parts of mine.

But it could be difficult as these two are completely different.


Alles Gute
