I was asked by a coworker for a few resources around unit testing in Ruby and figured I should collect them here rather than have to find them the next time someone asks me for them.

Here’s a quick post by Thoughtbot that gives newbies the basics of TDD.

IMO this article by Leigh Halliday goes in-depth a bit more into how to write good unit tests. That post also happens to link to this post by DHH which I feel brings up good points about following any doctrine without exception.

Here’s a fun talk from the creator of Minitest about Minitest 5 and what to expect from MT6.

And here is a talk I went to see at RubyConf2017 about how to evaluate tests called High Cost Tests and High Value Tests.

I’m sure these will come in handy to explain to folks in the future…
