Description:

• README example uses command that does not exist.
• GitHub Actions does not have it (ERROR: unknown command "test").
• Pip documentation does not have it (https://pip.pypa.io/en/stable/cli/).
• Online search does not have it (https://duckduckgo.com/?q=python+%22pip+test%22).

Action version:

• - uses: actions/setup-python@v2

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:

• 3.9.9
• Likely all versions

Repro steps:

1. Copy caching example from README under Caching pip dependencies into your GitHub Actions workflow.
2. Run it.
3. See ERROR: unknown command "test" under Run pip test action.

1. Remove the line - run: pip test
2. Actions finishes successfully.

Expected behavior:

• Successful action with successful caching.
• One possible alternative: pip check. However, is this necessary after running pip install?

Actual behavior:

• Command not found.
