+How to run:
+----------
+- single test class could be run by PyCharm and its pytest runner directly
+- OR
+- use Openpype command 'runtests' from command line
+-- `${OPENPYPE_ROOT}/start.py runtests`
+  
+By default, this command will run all tests in ${OPENPYPE_ROOT}/tests.
+
+Specific location could be provided to this command as an argument, either as absolute path, or relative path to ${OPENPYPE_ROOT}.
+(eg. `${OPENPYPE_ROOT}/start.py runtests ../tests/integration`) will trigger only tests in `integration` folder.
+
+See `${OPENPYPE_ROOT}/cli.py:runtests` for other arguments.
