Rethinking helpers for forms input about ember-test-helpers

[jgwhite]

My 2€…

It looks like testing-library’s type() behaves exactly as @simonihmig suggests — it doesn’t trigger blur, focusout, or change, it just types into the input and leaves the cursor blinking. I wonder whether users of testing-library ever get tripped up by this, expecting change to be called implicitly.

I suspect it would be beneficial for fillIn to more-closely model real user interactions, but agree the churn cost would be high. Perhaps we could introduce the enhanced behavior as an opt-in? Like a feature flag? With an eye to enabling it by default eventually?

import Application from 'acme/app';
import config from 'acme/config/environment';
import * as QUnit from 'qunit';
import { setApplication, enableFeature } from '@ember/test-helpers';
import { setup } from 'qunit-dom';
import { start } from 'ember-qunit';

setApplication(Application.create(config.APP));

setup(QUnit.assert);

enableFeature('fill-in-realistic-mode'); // <---

start();

Just wanted to add that there is also a beforeinput event that is not possible to test using the current helpers. If we're going to add additional helpers and/or modify the existing ones it would be great if we could also look at including that.
