Good Elixir TDD resources?

I’m not exactly sure what you are expecting.

GOTO 2015 • Agile is Dead • Pragmatic Dave Thomas:

The Ruby community is fantastic, it is wonderful, all right, I love the Ruby community. Over the last 12, 15 years I would say the Ruby community has done more to push foward testing than anyone else has done in the history of computing. They have a culture of testing but just not that, they’ve experimented with many forms of testing and they have produced a whole bunch of very cool frameworks which were then copied into other languages. So the Ruby community is really big on testing and I’m very proud of them for that, that’s great.

What I am not so proud of them for, it’s gone one step further and they now have this total bigotry about testing. So if you’re a Ruby programmer and you are not getting a hundred percent test coverage, they look at you and they go “I though you were a programmer. We’re not interested in your stuff, go away.” And they kind of have the backing of the majority of people because testing sounds like something you do, right?. I am going to tell you right now I mostly don’t test.

(I seem to recall that he stated of typically having about 60% test coverage.)

Anyway - TDD is a practice and if you have a competent testing framework like ExUnit you should be good to go - what other language specific support do you expect? And thanks to the Erlang community there is PropEr to replace some tedious static test cases.

Keep in mind that any practice should not be taken to the extreme of religion or dogma - that is counter-productive.

Practice TDD when it makes sense but keep in mind that it is just as important to delete those tests once they taught you all they can so that you don’t have to pay the cost of maintaining them (and don’t make the mistake of skipping Refactor in: Red, Green, Refactor - Why Refactor? - Economics).
