Node/22.8.0/Node Script Update To Experimental Test Coverage

Last update

Sep 10, 2024

Node.js now supports requiring code coverage to meet a specific threshold before the process exits successfully. To use this feature, you need to enable the --experimental-test-coverage flag.

Before

{
  "name": "my-project",
  "version": "1.0.0",
  "scripts": {
    "start": "node server.js",
  },
  "dependencies": {
    "express": "^4.17.1"
  },
  "devDependencies": {
    "jest": "^27.0.6"
  }
}

After

{
  "name": "my-project",
  "version": "1.0.0",
  "scripts": {
    "start": "node --experimental-test-coverage server.js",
  },
  "dependencies": {
    "express": "^4.17.1"
  },
  "devDependencies": {
    "jest": "^27.0.6"
  }
