.pre-commit-config.yaml for running encore tests

[echarrod]

I frequently found my deploys were broken because of a failing test, which I didn't realise for a little while.

Adding to pre-commit allows you to "shift left" the failures, so they are caught earlier, at commit time.

This is for use with https://pre-commit.com/, but I'm interested to hear how others have solved this.

Using the custom my-cmd-mod command provided on https://github.com/TekWizely/pre-commit-golang:

  - repo: https://github.com/tekwizely/pre-commit-golang
    rev: v1.0.0-rc.1
    hooks:
      - id: my-cmd-mod
        name: encore-test
        alias: encore-test
        args: [ encore, test, ./... ]

This does run all of the tests. Ideally we'd only run the tests for the changed packages, but I couldn't get it to work like that, as I'm not sure if we could "skip" the non-encore packages (if there are any).

This is similar to how the "go test" hook works, and -mod above can be substituted for the other prefixed below:

go-test

Automates testing, printing a summary of test results.

Hook ID	Description
go-test-mod	Run 'cd $(mod_root $FILE); go test [$ARGS] ./...' for each staged .go file
go-test-pkg	Run 'go test [$ARGS] ./$(dirname $FILE)' for each staged .go file
go-test-repo-mod	Run 'cd $(mod_root); go test [$ARGS] ./...' for each module in the repo
go-test-repo-pkg	Run 'go test [$ARGS] ./...' in repo root folder
