moduleForComponent stopped working in ember-source@3.13.0-beta.1

[ro0gr]

A simple moduleForComponent-style render test, like:

import { moduleForComponent, test } from 'ember-qunit';
import hbs from 'htmlbars-inline-precompile';

moduleForComponent('test', 'Integration | test', {
  integration: true
});

test('Test', async function(assert) {
  this.render(hbs`test`);

  assert.ok(true);
});

leads to the following error:

TypeError: Cannot read property 'lookup' of undefined

which is raised from

ember.js/packages/@ember/-internals/glimmer/lib/template.ts

Line 39 in 66ed9ab

let compiler = owner.lookup<LazyCompiler<StaticTemplateMeta>>(TEMPLATE_COMPILER_MAIN)!;

This error occurs starting from ember-source@3.13.0-beta.1 and still persists in ember-source@3.13.0-beta.3.

Here is a repo with reproduction - https://github.com/ro0gr/ember-moduleForComponent-owner

Thank you for reporting! I believe emberjs/ember-test-helpers#677 would fix, but I wanted to actually dig into things first to make sure we don’t make unneeded changes to the “legacy” testing system (if we can instead mitigate in Ember itself).

I've checked, the issue is fixed with emberjs/ember-test-helpers#677. Thanks!
