Hi \*, I have a few modules in lib/ and I use them mostly in my models.  
I’d like to add a few unit tests and run them with rake with all  
other tests of my app: where do I have to write them ?

TIA,  
ngw

Just follow naming conventions and throw them into the test/unit  
directory.

Jim is correct. Sorry I was so terse…should have explained myself  
better.

I found that by naming them something\_test.rb (and placing them in the  
test/unit directory as previously mentioned) the rake test:units task  
picked  
them up just fine.
