ember.js - ember-cli / ember-data model unit tests using http-mocks -

i using ember-cli / ember-cli-mocha testing. have generated http-mock work when run app via ember serve. however, when run tests -- (e.g. see below...), error:

sheet calculates exported fields      ✘ assertion failed: unable find fixtures model type (subclass of ds.model). if you're defining fixtures using `model.fixtures = ...`, please change `model.reopenclass({ fixtures: ... })`. 

i presume unit test setup must set store use fixtures. there configuration somewhere use http-mocks instead?

---

start of test ...

  'calculates exported fields', ->     # now, exported fields fields , variables     expected = `new set()`     sheet = null     store = @store()     ember.run ->       store.find('sheet', '1').then( (sheet_)->         sheet = sheet_         promise.all([ sheet.get('fields'), sheet.get('formulas')])       ).then((args)->         [fields, formulas] = args         fields.foreach (f)->expected.add(f)         ... 

answer on ember-cli home page:

mocks development. entire /server directory ignored during ember build , ember test.

however, there addon ember.js: ember-cli-testem-http-mocks
