Notes on things I learned & snippets of code that will make my life easier

}

How to test with mocha

In my project folder I create a test folder and create a test.js file inside the test folder.

Here is an example of test:

//how do I write a test using mocha
var assert = require("assert");

describe("In the ferry kata", function(){
	it("I should be able to create a car", function(){
	      //Assemble
      	//Act
	      //Assert
	   assert.equal("car", "car");
	});
});

Then to the terminal you get into the project folder that contains your test folder, test file and a function and you run 'mocha', this test will pass.

Here is another example of a failing test:

//a mocha failing test
var assert = require("assert");

      describe("In the ferry kata", function(){
      it(" I should be able to create cars", function(){
            //Assemble
            //Act
            //Assert
         assert.equal("car", "cars");
      });
});

When you run this test the same way as the first one, it will fail.
