ember_qunit.module undefined

When I run my integration tests from the brower localhost:4200/tests I get the following error

Uncaught TypeError: undefined is not a function

Inspecting the devtools window I see the error taking place on the following line:

ember_qunit.module

The weird thing is that if I run:

$ ember tests

All tests pass.

P.S. Seems like all the jsbin tests on the ember website are also failing, so I wonder if the two are related or if it is just a coincidence.

Were you able to figure out why you were getting this error?

No not yet. Just decided to ignore it and trust the command line version.

Perhaps if I upgrade to a later version of ember-cli the problem will go away.
