A Jest watch plugin to select Yarn workspaces to test
Install jest
(it needs Jest 23+) and jest-watch-yarn-workspaces
yarn add --dev jest jest-watch-yarn-workspaces
# or with NPM
npm install --save-dev jest jest-watch-yarn-workspaces
In your package.json
{
"jest": {
"watchPlugins": ["jest-watch-yarn-workspaces"]
}
}
Or in jest.config.js
module.exports = {
watchPlugins: ['jest-watch-yarn-workspaces']
};
Run Jest in watch mode
yarn jest --watch
Why is this not filtering my workspaces?
Make certain that you're using the SPACE key to toggle the selected state of workspaces and the ENTER key to confirm your settings.
