How did you handle "Expected at least one assertion, but none were run - call expect(0) to accept zero assertions."?

Hey Alex,

Have you used Test Double's verifying invocation feature in your Ember tests? Since td.verify() is meant to be an assertion, you end up getting an error like "Expected at least one assertion, but none were run - call expect(0) to accept zero assertions." if you don't call a method off of the provided assert. Just curious if you found any clever ways around this. 🙂

I ended up doing something like this in my own project. What do you think about adding it to this? I'd be happy to send a PR.

import td from 'testdouble';
import QUnit from 'qunit';

export default td;

export function verify(...args) {
  td.verify.apply(this, args);
  QUnit.assert.ok(true);
};

Hi @skaterdav85 this looks reasonable to me, but perhaps somebody else can chime in. Most of my usage for td has been in ember-cordova/corber where we're not using QUnit.

I build ember-cli-testdouble-qunit for this purpose. It sets up an assert.verify function that you can use

test('called a function', function(assert) {
  const stub = td.function();
  stub('foo');

  assert.verify(stub('foo'));
});
