Just a script on package.json to facilitate testing

package.json is a more obvious place to look for than .github/workflows/pull-request.yml if you want to know how to run the tests.

There is a failing test, which I don't think is related to this PR:

I've seen that one come up from time to time but not sure about it myself. Certainly not related to the PR.
