Handlebars error in component unit test

[jasonblanchard]

Hi all,

I just got liquid fire set up on my Ember app and everything looks good.

However, in a unit test for a component in which I'm using liquid-with, I'm getting this error:

Error: <(subclass of Ember.Component):ember307> Handlebars error: Could not find property 'liquid-with' on object <(subclass of Ember.Component):ember307>.
Error: <(subclass of Ember.Component):ember307> Handlebars error: Could not find property 'liquid-with' on object <(subclass of Ember.Component):ember307>.

I feel like the liquid-with helper isn't being registered properly in the test set up. I didn't see anything obvious in the docs...

I'm using ember-cli 0.1.12, ember 1.8.1.

Thanks!

edit:

Here's the test file, nearly boilerplate ember-cli except for the helper dependency:

import {
  moduleForComponent,
  test
} from 'ember-qunit';

moduleForComponent('editable-story-viewer', 'EditableStoryViewerComponent', {
  // specify the other units that are required for this test
  needs: ['helper:formatted-text']
});

test('it renders', function() {
  expect(2);

  // creates the component instance
  var component = this.subject();
  equal(component._state, 'preRender');

  // appends the component to the page
  this.append();
  equal(component._state, 'inDOM');
});

Your test has the comment:

// specify the other units that are required for this test

That means you need to list liquid-with. And liquid-with itself has dependencies, so the full thing will be something like:

['helper:formatted-text', 'view:liquid-with', 'view:liquid-child', 'template:liquid-with', 'helper:with-apply']

I got that list from liquid-with's own unit tests. It's annoying that the test infrastructure doesn't do transitive dependencies automatically.

Thanks!

Looks like I also had to add helper:liquid-with in the needs array.

Is this documented anywhere? Or is this this something folks should just dig through the liquid-fire unit test files to figure out?
