Error running git command in GitHub actions

[wmonk]

Just set this up and using in GitHub Actions, and this is the error returned.

Error: Command failed with exit code 128: git rev-parse HEAD^1
fatal: ambiguous argument 'HEAD^1': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
HEAD^1

Any ideas on this?

Github actions does a shallow checkout. I recommend the following:

    steps:
      - uses: actions/checkout@v2

      - name: Prepare repository
        run: git fetch --unshallow --tags

Brilliant, that's all working now! Thanks.

One other bit of config missing was appending --testLocationInResults to the jest command - probably useful to add this and the above to the README.

Sorry to spam!

We have two jest commands in our workflow. If both have a failing test, it only results in a single file annotation of which ever test run finishes last. I'm not familiar with actions/checks, but suppose it's to do with the same action writing twice.
