Acceptance tests fail due to inFlight recording with ember 1.13.4 data

I just updated my ember data from 1.0-beta-18 to 1.13.4 and fixed all issues except this one that comes up during my acceptance tests when I try to execute an destroy

application in my afterEach

.

Error: Assertion Failed: You can only unload a record which is not inFlight. `<frontend@model:user::ember2881:null>`

When I deactivate the route in the application, I do a user.save()

, which makes xhr go outside and triggers this crash when the application is destroyed. Removal user.save()

. I've tried updating to the latest ember-cli-qunit

and ember-qunit

with no luck.

Mine afterEach

looks like this:

afterEach: function () {
    Ember.run(application, 'destroy');
    ajaxMock.shutdown();
}

      

        
        
        
      

    

This was not a problem before the update. How can I fix or work around this problem?
