"""
Unit tests for vcs_ library.

In order to run tests we need to prepare our environment first. Tests would be
run for each engine listed at ``conf.SCM_TESTS`` - keys are aliases from
``vcs.backends.BACKENDS``.

For each SCM we run tests for, we need some repository. We would use
repositories location from system environment variables or test suite defaults
- see ``conf`` module for more detail. We simply try to check if repository at
certain location exists, if not we would try to fetch them. At ``test_vcs`` or
``test_common`` we run unit tests common for each repository type and for
example specific mercurial tests are located at ``test_hg`` module.

Oh, and tests are run with ``unittest.collector`` wrapped by ``collector``
function at ``tests/__init__.py``.
