jasmine-flight

Extensions to the Jasmine test framework for use with Flight

Getting started

Include jasmine-flight.js in your app and load it in your test runner.

Or install it with Bower:

bower install --save-dev jasmine-flight

N.B. jasmine-flight depends on jasmine and jasmine-jquery

Components

describeComponent('path/to/component', function () {
  beforeEach(function () {
    setupComponent();
  });

  it('should do x', function () {
    // a component instance is now accessible as this.component
    // the component root node is attached to the DOM
    // the component root node is also available as this.$node
  });
});

Mixins

describeMixin('path/to/mixin', function () {
  // initialize the component and attach it to the DOM
  beforeEach(function () {
    setupComponent();
  });

  it('should do x', function () {
    expect(this.component.doSomething()).toBe(expected);
  });
});

Event spy

describeComponent('data/twitter_profile', function () {
  beforeEach(function () {
    setupComponent();
  });

  describe('listens for uiNeedsTwitterUserId', function () {
    // was the event triggered?
    it('and triggers dataTwitterUserId', function () {
      var eventSpy = spyOnEvent(document, 'dataTwitterProfile');
      $(document).trigger('uiNeedsTwitterUserId', {
        screen_name: 'tbrd'
      });
      expect(eventSpy).toHaveBeenTriggeredOn(document);
    });

    // is the user id correct?
    it('and has correct id', function () {
      var eventSpy = spyOnEvent(document, 'dataTwitterUserId');
      $(document).trigger('uiNeedsTwitteruserId', {
        screen_name: 'tbrd'
      });
      expect(eventSpy.mostRecentCall.data).toEqual({
        screen_name: 'tbrd',
        id: 4149861
      });
    });
  });
});

setupComponent

setupComponent(optionalFixture, optionalOptions);

Calling setupComponent twice will create an instance, tear it down and create a new one.

HTML Fixtures

describeComponent('ui/twitter_profile', function () {
  // is the component attached to the fixture?
  it('this.component.$node has class "foo"', function () {
    setupComponent('<span class="foo">Test</span>');
    expect(this.component.$node).toHaveClass('foo');
  });
});

Component Options

describeComponent('data/twitter_profile', function () {
  // is the option set correctly?
  it('this.component.attr.baseUrl is set', function () {
    setupComponent({
      baseUrl: 'http://twitter.com/1.1/'
    });
    expect(this.component.attr.baseUrl).toBe('http://twitter.com/1.1/');
  });
});

Teardown

Components are automatically torn down after each test.
