Thanks for contributing. Skimming through the tests this basically turns the tests red as as soon as we change anything in the tested configuration files, correct? Could you elaborate on how this helps with catching errors / improving reliability?

[armano2]

those are just "simple" integration tests, that validate if configuration is correct and if rules are accepting provided options, as far as i can tell there was no way to validate tests options without using typescript.

---

i see that rules package got merged already and has types, it means that i could add tests that use typescript types to validate this.

Sounds good!
