Ember.js: Ember 2.14 - classCallCheck is not a function error while running tests in prod mode

[mani-mishra]

This is probably similar to #15506.
We have a CI task for running all our tests in both dev and prod mode.
We started this, when the app started failing in production, after an ember upgrade (everything was green in normal dev/tests mode).

So the same CI task is complaining of (0 , n.classCallCheck) is not a function).

Locally it can be reproduced by either running the tests on command line like,
ember test --environment production

TypeError: (0 , n.classCallCheck) is not a function

or

ember test --server true --environment production
and load chrome. One would see following,

Is there any updates on this ? Our app is still at 2.13.
Let us know if there is anything we can do the help.
We can raise a PR, with some guidance if needed.

On my environment, ember.prod.js works, only ember.debug.js produces the error. The version is 2.16.2 btw.

I believe this is fixed now. Tested with:

ember new foo
cd foo
ember g acceptance-test index
# edit test to pass properly
ember test --environment=production

@rwjblue Can you please confirm the ember/ember-cli version you tested with?
I tested with 2.18.0, still seeing the same error.

I think we need to migrate our app to latest versions.

I tested with current release versions of both Ember and ember-cli (3.1). Also, I just did a rudimentary test, so it’s possible there is something specific needed to repro that we haven’t discovered to date. Happy to reopen if I’ve closed in error.
