[PATCH] Add dynamic test loading

[Iain Lowe <me@…>]

Currently each test module imports all it's test suites explicitly in the __init__.py file. This means that every time you add a new test case to a suite (one of the modules under a *.tests package) or add a new test suite to a package (i.e. a new module to a *.tests package), you need to update another file. This manual updating is a bit of a pain; instead, I propose a dynamic test detection routine that picks up individual tests from modules, test suites from suite() functions and doctests from modules that have them.

The first patch modifies trac.test.suite() to crawl directories in the source tree and dynamically pick up tests. This causes breakage in certain modules which the second patch begins to address by cleaning out some unused suite-building structures.

Please note that this "solution" is incomplete: I would like to know if this direction is interesting to the TracTeam. If so, I will polish these patches and make sure that everything is tight and that all tests are running properly.

The attached patches are against the setuptools branch in the sandbox.

Have you checked how this interferes with ​peak:setuptools#test? In particular, it seems that the scanning facility is built-in (see ​peak:setuptools#test-loader).

You're right, it is. Sorry for the confusion.
