jasmineGetting started with jasmine

Remarks

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

        expect(response.statusCode).toBe(200);
        // this is your test assertion - it expects status code to be '200'
      });
    });
  });
});

Installing Jasmine using npm (Node Package Manager)

  1. Set up project directory for Jasmine

    Create a folder and run npm init this will create an empty package.json file and will ask some questions about your project to fill project json file.

    Add 2 directories app - for the Server and spec - for tests

  2. Get Jasmine

    From root project directory run

    npm install jasmine-node --save

    npm install request --save

    npm install express --save

    this will get you the packages

    ./node_packages/.bin/jasmine-node spec will run jasmine binary

    After this your package.json should look similar to this

    package.json file, after which that file should look like this:

  {
      "name": "Jasmine",
      "version": "0.0.1",
      "description": "Jasmine",
      "main": "index.js",
