I guess it was me talking about it two days ago on IRC...

Almost exclusively I need to run unittests only in the module I 
currently work on and it really makes no sense to run other 
unittests at that point of time (unless I explicitly want to). I 
would even go further to say that we basically need to be able to 
run particular unittest.

What I do at the moment is that I developed this kind of practice 
to have a test_runner.d top-level module in every D project of 
mine that contains tests I do during the development of 
particular feature TDD style, and then once I am done, I move 
this code to appropriate unittest blocks in my final module...

There are bunch of issues with existing support for unittests 
that could be solved to make unit-testing a really pleasant 
activity.
