2. Create and activate a virtual environment
3. To start the test_apps and run the test using run_tests script
   1. Run the test script .\run_tests\run_local.ps1 -AppPath v2\python\36
4. Alternatively, to get more error details and test manually
   1. resolve python dependencies by pip install .\test_apps\v2\python\36\requirements.txt
   2. start the function host by cd .\test_apps\v2\python\36; func host start
   3. run a test collection by python -m pytest .\tests\v2\python\36
   4. or run a specific test by python -m pytest .\tests\v2\python\36\test_v2_python_36_http.py::TestV2Python36Http::test_keyword_async_trigger
