I'm upgrading my Ember CLI addon from 0.1.9 to 0.2.0, and am hitting this error when running ember test --server:

ReferenceError: Can't find variable: define at http://localhost:7357/assets/test-loader.js, line 3

ember serve works, and I can visit /tests in the browser, but something else seems to have broken the testem/phantom setup.

I've upgraded Phantom, and went through the ember init diffs several times, but I must still be missing something.

The problem was I had used ES6 syntax in one of my files in /addon. ES6 isn't supported there (yet), so it was throwing this error.

Removing the ES6 (in this case, back ticks) solved the problem.

Update

Simply npm install --save ember-cli-babel in your addon to get Babel support for the files in your /addon directory.
