could not find module chai (new module unification)

[ghost]

I started migrating our app using https://github.com/rwjblue/ember-module-migrator/ and the https://github.com/emberjs/ember-module-unification-blueprint. The app builds successfully, but fails to load from the following error:

The import lines in that test file are:

import { expect } from 'chai';
import { describe, it, beforeEach } from 'mocha';
import Ember from 'ember';
import { initialize } from "web-server/src/init/initializers/application/initializer";
import destroyApp from 'web-server/tests/helpers/destroy-app';
import sinon from 'npm:sinon';

$ npm ls chai
└─┬ ember-cli-chai@0.4.2
  └── chai@3.5.0 

Our project's vendor.js does not appear to have chai loaded. This is a private repo but I am happy to test it / move this issue to a more relevant location.

@rwjblue @mixonic any ideas?

@efx I'm surprised moving to module unification would break this kind of import. Scanning the code chai should be in the vendor tree. If it was exposing the library via the app/ directory I would expect issues, but on the surface this looks fine.

I think this simply needs to be debugged. I don't see anything in that index.js that seems coupled to the app/ tree.

thanks folks. ah, interesting @mixonic. I can hop on ember slack for quicker back and forth then post conclusion here.

I was mistaken about not being included in the app. Chai does appear in dist/assets/test-support.js. I was thinking it should appear in vendor.js. I'll look at the require there;
...
I'm somewhat confused as this error occurs navigating to http://localhost:4200/ from ember serve. Double checking I installed the correct versions of resolve, etc

Turns out runningember build builds the app with module resolutions for tests. e.g. ember-test and all our application test files. This seems incorrect. It also seems like a resolver issue, not an ember-cli-chai. Open to direction on where to move this, ideas about useful further debugging.

Removing the test files fromsrc/initializers tree prevents this specific error from appearing. So it seems the -test files are not being excluded properly with ember build. This may relate to ember-cli/ember-load-initializers#42.

I'm closing this because the underlying issue appears caused by the initializer loading.
