Ask HN: How did you learn to properly build tests?
There's so many testing techniques out there, that I just can't seem to find a resource that describes mocking, stubbing, etc. in the real world. I get a lot of theoreticals of what they're supposed to be, but none of the how-do-I-apply-this-to-my-Rails-app.
Can anyone recommend resources on building unit, integration, and other tests, and what to test, what I should be looking for, etc.?
