Regression: Could not find a declaration file for module 'qunit-dom' on v1.6.0-beta.1

1. Clone this repo: https://github.com/johanrd/qunit-dom-typescript-reproduction
2. Run tsc, and experience the following typescript errors:

machine:qunit-dom-typescript-reproduction user$ tsc
tests/acceptance/application-test.ts:13:12 - error TS2339: Property 'dom' does not exist on type 'Assert'.

13     assert.dom('#ember-welcome-page-id-selector').exists();
              ~~~

tests/test-helper.ts:5:23 - error TS7016: Could not find a declaration file for module 'qunit-dom'. '…/qunit-dom-typescript-reproduction/node_modules/qunit-dom/index.js' implicitly has an 'any' type.
  Try `npm install @types/qunit-dom` if it exists or add a new declaration (.d.ts) file containing `declare module 'qunit-dom';`

5 import { setup } from 'qunit-dom';

yarn add @types/qunit-dom does not make any difference (as expected from deprecation).

Have I missed something from the migration guide and/or readme? Or is it an actual regression on v1.6.0-beta.1? thanks!

OK, that’s not going to be sufficient to test this, as qunit-dom is built and rolled up before it’s published. Try this:

• cd qunit-dom-typescript-reproduction
• yarn add https://github.com/simplabs/qunit-dom#e654d0e1c10fdb2b96f0255775ad66a2c0b24193 --dev
• cd node_modules/qunit-dom (this will install qunit-dom’s dependencies and build/rollup the package
• cd ../.. && yarn build (running yarn build is more appropriate than running tsc since it runs Ember’s build, which in turn will compile typescript)

Awesome. Thanks for testing this out!
