✨ A full-nonsense pet test runner ✨

So, what is this?

Software in the NodeJS ecosystem tends to depend a lot on external dependencies. What would a test runner without any look like? This is the question that started all of this.

womm is a pet test runner that follows the general direction of jest and playwright with a few additional constraints:

• It must not have any production dependencies (some development dependencies are permissible, like typescript and rome, but keeping it to a minimum);
• It must be compatible with the general API exposed by Jest and the like, for familiarity;
• It must use itself for testing.

Hot takes baked in

womm is an opinionated implementation of Typescript/Javascript testing libraries we've all come to get used to. You can peek at the opinions baked into this here.

Development

This uses Corepack, which comes bundled with node>=16 to manage which Yarn version to use.

To get started, just corepack enable before using yarn commands. You can also jump in by running . script/bootstrap, which will select the right version of Node, enable Corepack and install devDependencies.
