Mixins created in an addon fail default unit tests


Having an issue with mixins in my addon project. It’s pretty easy to reproduce the bug.

  1. Create a new add on with ember addon mixin-test.
  2. Go into the folder and ember g mixin mymixin.
  3. Run ember test.

I get this error:

not ok 8 PhantomJS 1.9 - TestLoader Failures: dummy/tests/unit/mixins/mytest-test: could not be loaded
        actual: >
        message: >

It looks like the mixin isn’t being properly imported into the test dummy application. I found this issue on StackOverflow that has the same error: http://stackoverflow.com/questions/29320833/ember-cli-0-2-1-generated-addon-test-cannot-find-mixin

But that seems like an issue with upgrading old projects, and it’s supposedly fixed in 0.2.2 which is the version I have.

Here is my version info:

version: 0.2.2
node: 0.12.1
npm: 2.7.4

I was able to deal with the error by creating a file in app/mixins that imports/exports the mixin from the addon folder, but shouldn’t this be done automatically?


I had this same issue with 0.2.3, and fixed it by changing:

import MyMixin from '../../../mixins/my-mixin';


import MyMixin from '[addon-name]/mixins/my-mixin';
