tijasmine Unit Test Demo

* Have a working project
- Note that i created a utils.js file in the lib folder with my business logic methods
e.g.

exports.concatName = function(a,b) {
	return a.substring(0,1).concat(b);
}

* Download tijasmine from https://github.com/billdawson/tijasmine

* Download jasmine from https://github.com/pivotal/jasmine
- we will use 1.3.1 from the dist folder

* As per the tijasmine instructions copy jasmine.js (from jasmine/dist/{unzip 1.3.1}/lib) and tijasmine.js and tijasmine-console.js (from tijsamine/src) and place in your projects lib folder

* Create a specs folder under the apps folder for your jasmine unit tests (this is standard jasmine stuff)

* Add unit tests and note to add “require("tijasmine").infect(this);” at the top of your unit test file
e.g. specs/myspec.js:

require("tijasmine").infect(this);

var utils = require('utils');

describe("utilities", function() {
	it("Concats two fields together", function() {
		expect(utils.concatName("Leor","Brenman")).toEqual("LBrenman");
	});
	it("Concats two fields together", function() {
		expect(utils.concatName("Leor","Brenman")).toEqual("lBrenman");
	});
});

* In the test above, i am creating a passing test, followed by a failing test for demonstration purposes

* In your index.js, initiate a test using the following code:

var tijasmine = require("tijasmine"),
    reporter = new (require("tijasmine-console").ConsoleReporter)();

tijasmine.addSpecModules("/specs/myspec");
tijasmine.addReporter(reporter);
tijasmine.execute();

* Launch your app on an iPhone device/simulator or Android device/emulator and review the console log, e.g.:

…
[INFO] :   ------------------------------------------------------------
[INFO] :   utilities:
[INFO] :   - Concats two fields together (ok)
[INFO] :   - Concats two fields together (FAILED)
[INFO] :   - - Expected 'LBrenman' to equal 'lBrenman'.
[INFO] :   ============================================================
[ERROR] :  THERE WERE FAILURES!
[ERROR] :  ============================================================
[ERROR] :  Recap of failing specs:
