[Qt-creator] plugin_qtestlib

Adam, you are exactly correct.
Then following your logic, if test is run, but not recompiled, 
then there's no build stage happening and no running of a test.
(if running of test is part of building).


I think we are just talking about different things here.

Let's clarify the scenario we are talking about here.
First facts:
1. You are saying there's a main application, say app.exe, right?
2. There's unit testing code for some classes of that application. 

Now questions:
1. Do you have test code separate from you production code or together with it?
2. How do you run these tests? Do you have test.exe or do you have a test mode of app.exe?
3. What happens if app.exe is actually not an application, but a library library.dll?

When answering these questions, just remember that we need to cover all the cases...

Running the unit tests is conceptually part of building your
application. You don't have to clean and recompile your entire
application every time you make a little change; why is this any
different? Running the "Test" step doesn't have to recompile the whole
mess if it's already built (and, ideally, up to date).
