Cannot `import Bugsnag from 'bugsnag'` in test environment

I'm using the `Bugsnag.notify` API and therfore have to

``` javascript
import Bugsnag from 'bugsnag';
```

However, this breaks my tests:
> Chrome 43.0 - Global error: Uncaught Error: Could not find module `bugsnag` imported from

Any suggestions here? I'm curious why `index.js` explicitly does not include bugsnag in `test` environments.

``` javascript
// index.js
this._includeBugsnag =
this.isDevelopingAddon() || process.env.EMBER_ENV !== 'test';
```

Any chance we could import just the `bugsnag/shim` in `test` environments?
