title: How to reference a directory in my repo during a GitHub action build?
body: <p>I have some test data that I use for unit tests with pytest. I set their location with environment variables. Looking at my pytest logs the build sees the environment vars but the locations they reference don't exist. In the GitHub Actions docs the repo should be in /home/runner/Repo/. Below is my folder structure. Anyone see any obvious issues?</p>
  
  <pre><code>Repo/
    notebooks/
    repo/
      __init__.py
      tests/
        tests_db.hdf5
        Sample_Raw/
          ...
        __init__.py
        test_obj1.py
        test_obj2.py
      obj1.py
      obj2.py
      utils.py
