Mokamok

Zero configuration JavaScript Unit Testing with Mocha, Chai and Sinon

Install

$ npm install --save-dev mokamok

Getting Started

In order to use the latest babel preset we need to install it:

$ npm install --save-dev babel-preset-latest

Create a directory called --tests--, and add a test file increment.spec.js:

import increment from '../increment';

describe("increment.js", () => {

    it("should increment the value", () => {
        expect(increment(7)).to.equal(8);
    });

});

Let's implement the increment.js module:

export default function (v) {
    return v + 1;
}

Modify the package.json file:

"scripts": {
    "test": "mokamok"
},

Run the test:

$ npm test
