I have found the load_tests protocol to be suitable for this purpose
and highly flexible. The load_tests() function accepts a loader:
load_tests(loader, standard_tests, None)
What I have done is add a "test_config" attribute to the loader before
calling unittest.main() (or whatever variant you might use). The
test_config attribute carries whatever runtime information you'd like
the tests to depend on. Then in each module, the load_tests function
can modify the standard tests based on test_config, or even pass
test_config to the test cases themselves. In the latter case, you can
write your unittest.TestCase test methods to depend on test_config
