Gist of the Day: Test::MockModule for Repeatable Tests!

I like repeatable tests. The #1 benefit of repeatable tests is that they’re repeatable. This also means they’re less vulnerable to data changes (e.g. this test depends on this product record remaining unchanged) and don’t pollute your environment. There are two ways that I think you can make your tests repeatable, and I think both of them are equally valid, and each should be used in their appropriate time:

I actually have had a couple of days where my experiment for the Gist of the Day failed, and I couldn’t get something working in time to put it up.
Today, however, I do have something for you!
Today we are going to cover two topics very briefly (as usual): 1) how do you factor files you wrote into your tests, and 2) how do you write your code with testing in mind (which you should). Continue reading “Gist of the Day: How to Test a File You Wrote!”
