Usage: ${CMDNAME} [FLAGS] [TESTS_TO_RUN] -- <EXTRA_NOSETEST_ARGS>

Runs tests specified (or all tests if no tests are specified)

Flags:

-h, --help
        Shows this help message.

-i, --with-db-init
        Forces database initialization before tests

-s, --nocapture
        Don't capture stdout when running the tests. This is useful if you are
        debugging with ipdb and want to drop into console with it
        by adding this line to source code:

            import ipdb; ipdb.set_trace()

-v, --verbose
        Verbose output showing coloured output of tests being run and summary
        of the tests - in a manner similar to the tests run in the CI environment.
