# If the tox env name contains "-cov", we run the test suite through the

# The {posargs} are positional arguments passed to the 'tox' script after the
# '--' separator. E.g. you can use them to run a specific test module in tox:
#   $ tox -- Lib/mutatorMath/test/ufo/kerningTest.py
# With no {posargs}, tox will run the whole test suite in verbose mode.
