The basic idea of snapshot testing is that you compare the output of your code against a file that’s written on disk. That file is called a snapshot. If the output of your test matches up with the contents of that snapshot, it succeeds, otherwise, it fails. It’s a simple as that.
In this talk we’ll demo how you can add snapshot testing methods to PHPUnit and review a practical example on how to us them.
