Reporter for Jest that outputs GitHub Actions annotations
npm install jest-github-actions-reporterA custom Jest reporter to create annotations when run via GitHub Actions.

All you have to do to get annotations in your GitHub Actions runs is to add the reporter your Jest configuration.
1. Install npm install -D jest-github-actions-reporter
2. Add to your jest.config.js:
``js`
module.exports = {
reporters: [
"default",
"jest-github-actions-reporter"
],
testLocationInResults: true
};package.json
alternatively you can only add it during your CI build, for example in :`json`
{
...
"scripts": {
"citest": "CI=true jest --reporters=default --reporters=jest-github-actions-reporter"
}
}
nothing else is required, no token sharing, no REST API calls etc.
