testaged-coverage

---

Use this library to execute tests on your git staged files and verify they comply with the test coverage threshold.

Before the tests are run, make sure you have set a Jest "coverageThreshold". You can learn how to configure it here.

{
  ...
  "jest": {
    "coverageThreshold": {
      "global": {
        "branches": 80,
        "functions": 80,
        "lines": 80,
        "statements": -10
      }
    }
  }
}

How to use it

You need to stage your files first with gir add.

In a pre-commit hook

You will need to have husky installed. In your package.json, add the script to run as a pre-commit hook.

// package.json
{
  "husky": {
    "hooks": {
      "pre-commit": "node ./node_modules/testaged-coverage && <you can include other scripts here (e.g. lint-staged)>"
    }
  },
}

Directly in command line

Just execute node ./node_modules/testaged-coverage
