Introduction

I hear you want to try Mockist style TDD in JavaScript	I do! I do!
What do you want to build?	A chat room with a wisdom bot in AngularJS
We start by writing an acceptance test.	Yes and for now they will be manual.
Why not automate it?	I will, just not in this Kata.

Starting

Open a new chat window and type: server.sh

Now navigate to: ``http://localhost:8000/index.html

Now I want to make the chat bot welcome me with a random greeting when I enter the room!	For that we'll need a controller so let's add that to our route. First another test on our route: ... it('should use the chatroom template', function() { expect(route.templateUrl) .toEqual('/chatroom/chatroom-template.htm'); }); ... it('should use the ChatRoom Controller', function() { expect(route.controller) .toEqual('ChatRoomController'); }); }); Now you have another red test, lets make it green! In app/js/app.js modify the route to look like this: $routeProvider.when('/chatroom', { templateUrl: '/chatroom/chatroom-template.htm', controller: 'ChatRoomController' }); Your test should now be green! Is it?
Ok, my route has a controller but still don't have a random greeting from the bot! It still just says Hello World.	Now that we have a controller, we can add some logic to our page. First, let's add a test. In chatroom-controller-tests.js add this test: describe('when entering the room', function() { it('should get a random greeting from the chat bot', function() { expect(mockChatBot.getRandomGreeting.called).toBeTruthy(); }); });
Now I'm getting an 'undefined' error.	This is because the getRandomGreeting method doesn't exist yet on the ChatBot service. Add the following inside app/chatroom/chatbot.js: return { getRandomGreeting: function() { } }
Now I'm getting the error 'Expected false to be truthy'	This is our failing test! We're expecting our controller to call getRandomGreeting, but it's not. Let's make it pass! Add this inside app/chatroom/chatroom-controller.js: return { getRandomGreeting: function() { } }
