Questions or comments

To test controllers i have added this to composer.json

    "autoload-dev": {
        "classmap": ["app/code/*/*/*/controllers"],

Should we use it for core too? Ping @justinbeaty.

I skimmed it.. 😅

That's a lot of coverage now, nice work!

Thanks.

Total coverage is still below 10%, but starting with around 40 test last year and now having 800 is not so bad.

I'll try to add more frequently.
