Testing and tooling

[alanvardy]

Hello,

Would you be interested in me adding any of the following?

• Unit tests
• Credo
• Standardized formatting by enforcing mix format?
• Mix Check https://github.com/karolsluszniak/ex_check (Runs all tests/checks/tools in parallel in dev)
• GitHub Actions

I would say yes to Unit tests, credo and GH actions, feel free to add in mix check since I know you're a fan 😉 as long as it doesn't override mix test!
