runtests.py [OPTIONS] [-- ARGS]

Run tests, building the project first.

Examples::

    $ python runtests.py
    $ python runtests.py -s {SAMPLE_SUBMODULE}
    $ python runtests.py -t {SAMPLE_TEST}
    $ python runtests.py --ipython
    $ python runtests.py --python somescript.py
    $ python runtests.py --bench
    $ python runtests.py --durations 20

Run a debugger:

    $ gdb --args python runtests.py [...other args...]

Disable pytest capturing of output by using its '-s' option:

    $ python runtests.py -- -s

Generate C code coverage listing under build/lcov/:
(requires http://ltp.sourceforge.net/coverage/lcov.php)

    $ python runtests.py --gcov [...other args...]
    $ python runtests.py --lcov-html
