generator-bdd

A Yeoman generator that makes it easy to start writing unit tests within your Node.js application. It will add mocha, chai, sinon and istanbul to your application. It will also add 2 .js files. One containing the system under test and the other a failing test against the former.

How to

Install Yeoman and generator-bdd using the following npm command:

$ npm install -g yo generator-bdd

cd to your application's directory that contains already a package.json, then:

$ yo bdd

The generator will add/update the following items to your application:

application
├── node_modules
│   ├── chai
│   ├── istanbul
│   ├── mocha
│   └── sinon
├── package.json
├── test
│   └── greeter.spec.js
└── greeter.js

In particular it will add 2 npm scripts to your existing package.json

{
  "scripts": {
    "coverage": "istanbul cover _mocha test --  --recursive",
    "test": "mocha --recursive"
  }
}

At the very end of its execution, the generator will also run npm run coverage that will produce a coverage report
