Ember integration tests no longer work

[keithbro]

After installing ember-cli-i18next, integration tests stop working. Steps to reproduce.

ember new foo
cd foo
mkdir tests/integration
wget -O tests/integration/index-test.js https://gist.githubusercontent.com/keithbro/043b1c12658e7555daf8/raw/d1a7f6b26bced070ae195d9f67fc65e404b292a2/index-test.js
ember test

At this point the tests pass.

ember install:addon ember-cli-i18next
bower install --save i18next
ember test

Now the tests start running but do not complete. No error message:

Running the tests through the web browser gives a bit more info (http://0.0.0.0:4200/tests)

Is the project dead?
I would like to use this plugin too
