“Test Focus Highlighter” VS Code extension
I’m really excited to share a new VS Code extension called “Test Focus Highlighter”. 🎉
It’s an extension that visually highlights focused tests in spec files. Here’s a demo:
Why did I build it?
Primarily for myself. I started writing tests for my code a few months ago and mistakenly committed focused tests in a couple of occasions. They were, fortunately, catched during pull request (PR) review but that is already too late in the process. I saw this as an opportunity to make a small tool that can help me identify focused tests during development by visually highlighting them. And when I say visually, I mean really making them stand out.
The extension does this in three ways:
- Shows a warning icon in the gutter for each line covered by a focused test.
- Shows a warning message when a focused test is hovered.
- Shows a color in the overview ruler that makes it easy to see any focus tests in a big spec file.
The extension will not prevent one from committing focused tests. It only aims to increase ones chances of catching such tests as early as possible.
I hope you will find the extension beneficial as well!
