Sometime testing our JavaScript code becomes a tough task. Jasmine is a behavior-driven development framework for testing our JavaScript code. It does not depend on any other JavaScript frameworks. It does not require a DOM. And it has a clean syntax which makes you easily write the tests. You can find the Jasmine documentation here and the project in GitHub.

Hello World

To create a most basic test with Jasmine go to your spec (tests) folder and add file named testSpec.js .

In that file add following:

var request = require("request");

describe("Hello World Test", function() {
  // This is your test bundle

  describe("GET SO", function() {
    //This is testing that http GET works

    it("Checks if SO is online", function() {
      // This is description of your test - this is what you get when it fails
      request.get("http://stackoverflow.com/", function(error, response, body) {
        // this is your test body

        // this is your test assertion - it expects status code to be '200'
