exactly. And all that is part of the semantics of a particular test
type. So you have to write a test class (in python) which, in it's 'Run'
method does whatever you want to actually test.

Yes, you need to tell qmtest how your tests map to your code. As I
originally used Makefiles to drive that, I wrote a qmtest database
that uses some 'Makefile'-like scripts that are actually python code,
but which are the user-visible access point, i.e. where he adds tests to
the database. That's where I would define the environment (build
variables, say), and the tests (source file and other test specific
resources needed to run it).

Toolsets nicely map to qmtest's 'context'
Again, what I did (based on make, not bjam) is to have a toplevel
'Makefile' setting up the database for a specific platform. All
subsequent 'qmtest run' executions will use those parameters, so you
have a mapping between test database instance and toolset.

I think it's well worth the efford (and not that hard). If anybody wants
to try, I'd be willing to help (though you may prefer to take the
discussion off of this list).
