[5.x] Scaffold PHPUnit test suite with make:addon command

[duncanmcclean]

This pull request improves the php please make:addon command by automatically scaffolding a PHPUnit test suite alongside new addons.

This PR, combined with #9573, will streamline the process of setting up addon tests suites, ultimately saving time for addon developers. ✨

The composer install step failed for me. Not sure how it passed for you. It was complaining about a plugin not being allowed.

Adding this to the composer.json.stub fixes it:

    "config": {
        "allow-plugins": {
            "pixelfear/composer-dist-plugin": true
        }
    }

Also, the tests don't want to run for me. Did they work for you?

Funnily, using VSCode's "Better PHPUnit" extension to run the test from the file itself does work:

Weird, it was definitely working for me. 🤔

Anyways, I've added that plugin to the composer.json stub. Maybe try again and see if it works this time?

It'll be because the AddonTestCase is only available on master but when it installs statamic/cms in the addon, it's installing the latest v4 tag which doesn't include that class.

You probably need to symlink your local cms repository before running the tests. Once v5 is tagged, this shouldn't be an issue.

You're right!

I changed the stub to "statamic/cms": "dev-include-tests-in-make-addon-stubs as 4.50.0", ran make:addon, and I was able to run the tests immediately. That way it could work without needing to symlink my cms first.

Since it works, I've bumped the constraint to ^5.0 since that's what it's gonna be when this is shipped.
