Test failures after upgrading from 0.1.12 to 0.2.0

Ember CLI
1

From only updating my code from ember-cli 0.1.12 to 0.2.0, my tests started failing with:

Called start() while already started (test's semaphore was 0 already)

It seems very similar to this: Weird behaviour in test runner after update to 1.10 + 0.1.15 combo

and possibly this: http://octopushub.org/ember-cli/2015/02/08/githubcom-poteto-embercliflash.html

Did anyone else come across this? I’ve reverted back to my previous version of Ember CLI 0.1.12 in the meantime, but I don’t want to stray too far away from the latest version.

I’ve also had this issue.

This may not be helpful for you, but I was able to resolve it by making my beforeEach synchronous. I had a promise .then call in beforeEach…
