Update of /cvsroot/python/python/nondist/sandbox/setuptools/setuptools/tests
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv17806/setuptools/tests
Modified Files:
test_resources.py
Log Message:
Add tests for AvailableDistributions().resolve(). This effectively
completes the core dependency resolution engine; all we need now is a way
to turn sys.path entries into "distribution sources" that can list
Distribution objects for inclusion in an instance of
AvailableDistributions, and the 'require("SomePkg>=2.7")' API will be
usable.
