Test helpers for your integration tests that fire native events

// This is a wrapper around `@ember/test-helpers` that we need for compatibility
// reasons. Apps and addons using ember-qunit v4 aren't supposed to depend directly on
// `@ember/test-helpers` and just use the one that their version of
// `ember-qunit` or `ember-mocha` provides.
// Apps and addons using ember-qunit v5 directly depend on
// `@ember/test-helpers`.

  // at this point, so its exports are still undefined.
