Debugging Tests

Running tests through testrepository makes it difficult to use pdb for debugging them. oslotest includes oslo_debug_helper to make using pdb simpler/possible.

First, add a pdb call to the test code:

import pdb; pdb.set_trace()

Then run the tests through oslo_debug_helper like

$ oslo_debug_helper [tests to run]

or

$ tox -e venv -- oslo_debug_helper [tests to run]
