Feature request against unittest2. Issue 18: https://code.google.com/p/unittest-ext/issues/detail?id=18

As providing a file path instead of module name to the unittest command line runner currently fails there is no backwards compatibility issue with making this work.

The only potential issue is if a test suite or module is genuinely 'foo.py' then we could end up attempting to load the file instead of the specified suite / module. To get round this we should only attempt to load tests from a file by checking the file exists first.

The specified still needs to be *imported* to load tests from it, so the file path will be converted to a module name by replacing path separators with '.'.

The way to execute test files that aren't importable as modules is to execute them directly not using python -m unittest.
