[Distutils] [buildout] testing framework - avoiding os.popen calls

[Tarek Ziadé]

Hello

Right now when people write tests with zc.buildout, to try out their
buildout they roughly do:

>>> from zc.buildout.testing import system
>>> system('bin/buildout -c my-config.cfg')
...
usual output
...

The problem is, the system() function uses os.popen to call the buildout
script, making it hard to debug.
For instance, you are not able to put a pdb and trace as you would do in the
same program, which is painful

What about adding in zc.buildout.testing a new function called "buildout"
that could be used to run
a buildout in the tests/doctests the same way :

>>> from zc.buildout.testing import buildout
>>> buildout('my-config.cfg')
...
usual output
...

I could do a branch for that but if everyone agrees, I guess I can push that
extra function into the trunk
