Custom events by ember-gestures are not working in testing using ember-test-helpers

I am writing a ember component ember-slider. I wrote some basic test cases for the component. But when I tried to write a test case triggering ‘tap’ event using ember-test-helpers, the event was not recognised by “ember-gestures” add-on which I am using capture user actions like tap and pan.

Following is the code I am using to test the tap functionality. Please help me figure out what is going wrong. I am not sure if I have provided enough detail here. Please let me know in case if more required.

test('tap to change value', async function(assert) {
     assert.expect(2);
     await render(hbs`{{ember-slider initialValue=10}}`);
     assert.equal(parseInt(this.$('.slider-value')[0].textContent), 10, 'Value set to 10');
    
     // The following jQuery event callback is called after tap('.ember-slider'); gets executed. But the tap event inside my component is not.
     this.$('.ember-slider').on('click', function(e) {
       console.log("Entered ", e);
     });
     
     await tap('.ember-slider');
     assert.equal(parseInt(this.$('.slider-value')[0].textContent), 0, 'Value set back to 0 by tapping');
});

OK, @rondale-sc and I spent some time poking at this this morning. Somewhat random brain dump follows…

• We created a repo to show the failure (mostly following from my last comment) here.
• Hammer.js uses fallback logic to determine which events to hook into and use for firing the tap event. That fallback logic is here.
• The tests in that repo pass on Safari (does not support PointerEvent) but not on Chrome (supports PointerEvent).
• The internal fireEvent helper function is not aware of PointerEvents, and for touchstart / touchend events we fire the generic Event.

Action items:

• Add support for touch events to the fire event helper
  • Use PointerEvent when window.PointerEvent is present and fallback otherwise
• Add Hammer.js as a dev dependency to this repo (either via ember-gestures, or just as an app.import) along with a smoke test like the one written in the demo repo above to confirm tap continues to work with Hammer.js.

@eriktrom I checked it with 1.0.0 version. The issue is still there. May be it is related to what @rwjblue mentioned.
