A base to easily run Jest with SWC.
If I should maintain this repo, please ⭐️
DM me on Twitter if you have questions or suggestions.
This package bundles Jest and SWC together, providing an fast and easy way to run tests.
It comes preconfigured to work with TypeScript and ESM.
yarn add --dev @autosoft/jest-preset
npm install --save-dev @autosoft/jest-preset
pnpm add --save-dev @autosoft/jest-preset
In your package.json
file:
{
"jest": {
"preset": "@autosoft/jest-preset"
}
}
Now to run jest, run yarn jest
or npm run jest
.
All tests will need to be in the test
directory and end with .test.ts
. Additionally, coverage will be collected from all files in the source
directory.
