backbone-koans's Introduction

Backbone Koans

A set of jasmine powered koans for learning Backbone.js.

The koans verify behavior of a Todo list app, a modified version of the original Todos app created by Jérôme Gravel-Niquet.

How to Run

Start a local http server from the backbones folder:

python -m SimpleHTTPServer
(or 'python3 -m http.server' for python 3 users)

http://localhost:8000/

Some browsers such as Chrome don't like you making some json requests through the 'file' protocol, so just opening specrunner.html directly from a browser is not recommended.

On opening the localhost:8000 page in the browser you will see many failing specs. Work your way through the jasmine specs in the js/koans directory, and when you finish you should have a better understanding of how to create and test a Backbone app.

backbone-koans's Issues

bind('all') koan

Hi there,

I'm doing your koans (great work, by the way, thanks a lot!) but I'm stuck at the bind('all') one:

https://github.com/larrymyers/backbone-koans/blob/master/js/koans/aboutEvents.js#L66

The solution should be obj.trigger("custom event");, but it doesn't work. It triggers two events instead of one, so first assertion is not valid.

I'm I doing something wrong? This is my code:

it("Evented objects can bind 'all' as a special event name to capture all triggered events on the object.", function() {
  var callback = jasmine.createSpy('-Custom Event Callback-');

  obj.bind('all', callback);

  obj.trigger("custom event");

  expect(callback.callCount).toBe(1);
  expect(callback.mostRecentCall.args[0]).toBe('custom event');
});

Cannot use 'in' operator to search for 'id' in text

Hi,

I can't seem to work out why the following code is throwing an error:

it('Attributes can be set on the model instance when it is created.', function() {
    var todo = new Todo({ text: 'Get oil change for car.' });
    var expectedText = 'FIX ME';
    todo.set('text',"FIX ME");
    expect(expectedText).toEqual(todo.get('text'));
});

The console states: TypeError: Cannot use 'in' operator to search for 'id' in text -> koans/aboutModels.js:24

Any idea where I've gone wrong?

Thanks
