QUnit.test('applying several mixins at once with sup already defined causes infinite loop', assert => {
  let cnt = 0;
  let MixinA = Mixin.create({
    foo() { cnt++; }
  });

  let MixinB = Mixin.create({
    foo() {
      this._super.apply(this, arguments);
      cnt++;
    }
  });

  let MixinC = Mixin.create({
    foo() {
      this._super.apply(this, arguments);
      cnt++;
    }
  });

  let obj = {};
  mixin(obj, MixinA); // sup already exists
  mixin(obj, MixinB, MixinC); // must be more than one mixin

  cnt = 0;
  obj['foo']();
  assert.equal(cnt, 3, 'should invoke all 3 methods');
});
