In PHPStorm, when I'm surveying a file, especially a big test class with lots of test methods, I used to collapse all functions to make it easier to navigate.
But recently, I was pairing with Aaron, and he showed me the Structure view.
This is way easier for scanning and jumping around a file, and it's only a keystroke away (Cmd-7 on macOS).
It's also not unique to PHPStorm. I'm sure a similar feature exists if you prefer a different editor.

P.S. Wish your Laravel app had good test coverage like this? We can help with that!
