    1. To activate the newly prepared ypkg_test_venv, execute:

        source ypkg_test_venv/bin/activate /
        source ypkg_test_venv/bin/activate.fish / 
        source ypkg_test_venv/bin/activate.zsh

      ... depending on which shell you use.

    2. When you are done testing, execute:

        deactivate

      ... to exit the ypkg_test_venv venv.

    3. To run the integration tests, execute:
    
        ./run_release_tests.sh

      ... this will run in a clean checkout + ypkg_test_venv
          and will deactivate the ypkg_test_venv venv after
          run is done.
