Error on generated Adapter unit tests

[pkenway]

I'm getting an error running unit tests for the DRF adapter and subclassed adapters.

See the following gist for an example:
https://gist.github.com/pkenway/9e77ca425d91fe925482

This is the error I get:

not ok 1 PhantomJS 1.9 - ApplicationAdapter: it exists
    ---
        actual: >
            null
        message: >
            beforeEach failed on it exists: 'undefined' is not a function (evaluating '(function () {
                  return ENV['default'].APP.API_HOST;
                }).property()')
        Log: >
    ...
ok 2 PhantomJS 1.9 - JSHint - unit/adapters: unit/adapters/application-test.js should pass jshint

This is with ember-cli 0.2.2.

Am I doing something wrong or is this a bug?

I figured out the issue. I was including the adapter in an addon, which by default has the prototype extensions disabled. I uninstalled ember-disable-prototype-extensions and it's fixed.

Good to know. This sounds like something we should document.

Ember-cli 0.2.4 includes ember-disable-prototype-extensions by default so we should probably figure out why the tests don't work when the prototype extensions are turned off.

Here's some information about the module:

This is a great idea for addon authors to ensure that their addon does not accidentally
depend upon prototype extensions (which may be disabled in a consuming application).

The PR into ember-cli also has some useful information:

Yes, we need to update to 0.2.4 and fix this issue.

Do you want me to investigate / fix this issue before you merge #89?

[dustinfarris]

Yes, thanks.
