Notes Used to Craft this Lesson
DRY stands for Don't Repeat Yourself and in testing, it is easy to accidentally repeat yourself if you need to test the same thing using different inputs or outputs.
That's where the magic of datasets in Japa comes in to help. We can easily use them to define an array of data to run a single test with, so that we don't have to copy/paste that test over and over again, keeping them nice and DRY.
