Vim Mark That Test! 🔖

This week Chris Erin taught me a technique that has changed my testing game: Vim mark your current Ruby test with mA.

When writing TDD-style code in a test-crazy language like Ruby, I tend to follow a predictable workflow: create a test, watch it fail, bounce around the code making changes, and run/edit the test again. This loop can repeat for hours on a complex feature.

There are many ways you could navigate back to your test from elsewhere; a very efficient method is to mark it in Vim with mA. Like any mark, you can return to it with `A. Why 'A'? Capitalized marks are file marks and are valid between files. With this command, you can mindlessly jump back to your test from anywhere in the jumplist stack.
