ember-test never terminates with COVERAGE=true about ember-cli-code-coverage HOT 14 CLOSED

Are you by any chance using ember-cli-mirage?

I noticed that the request.onload callback never got called. This might be caused by pretenderjs (even though the request was made and I had a passthrough rule in mirage/config.js).

In my codebase in tests/helpers/destroy-app.js there was a missing line server.shutdown();.

Here the full file which solved the issue for me:

tests/helpers/destroy-app.js

import Ember from 'ember';

export default function destroyApp(application) {
  Ember.run(application, 'destroy');
  server.shutdown();
}

from ember-cli-code-coverage.

I've seen this as well but only with addons that have acceptance tests. If I skip the acceptance test then the run completes and reports coverage.

The issue is back for me with 0.3.9 but 0.3.8 is still good

My builds stopped working with the same behaviour, it seemed to appear randomly. I guess this might be a dependency issue?

@rox163 Thank you! That was causing the freezing for me too.

from ember-cli-code-coverage.

That was exactly my problem too. Thank you. 😲

Still having this issue with version 0.3.9 even with the above solution. Reverting to 0.2.2 fixed it for me.

Hopefully solved by #87

from ember-cli-code-coverage.

#87 has been released in 0.3.10

from ember-cli-code-coverage.

Duplicates with #88?

from ember-cli-code-coverage.

I opened this ticket over a month before 88.
Anyways, the hanging issue is fixed for me after upgrading to 0.3.10 ( and previously having applied topaxi's fix ).

Was still seeing this in 0.3.10. I'm using mostly default generated tests with ember 2.10 and ember-cli-mirage. It must have been a problem with a mirage instance never getting shutdown and hanging around. Resolved it by adding if(server !== undefined) { server.shutdown(); } to beforeEach and afterEach in each acceptance test file. As in,

module('Acceptance: Metro', {
  beforeEach: function() {
    if(server !== undefined) { server.shutdown(); }
    application = startApp();
    originalConfirm = window.confirm;
    window.confirm = function() {
      confirmCalledWith = [].slice.call(arguments);
      return true;
    };
  },
  afterEach: function() {
    Ember.run(application, 'destroy');
    window.confirm = originalConfirm;
    confirmCalledWith = null;
    if(server !== undefined) { server.shutdown(); }
  }
});

Hope this helps someone else having the same problem.

@topaxi - that mirage server.shutdown() trick saved my ass. If you're ever in the Chicago area, your drink's on me.

I had the same problem. Because of Integration tests where I use New Testing API.

I had to close mirage server (server.shutdown()) after every Integration tests. Here is quite neat solution for folks that will strugle with this in the future:
