Adapter not recognized by karma

See original GitHub issue

As of today, getting the following error:

Firefox 34.0.0 (Mac OS X 10.10) ERROR
  You need to include some adapter that implements __karma__.start method!

We are running karma 0.12.19, karma-mocha 0.1.6, and mocha 1.21.3. Tried updating everything to the latest versions with the same result.

@NullVoxPopuli it looks like a bug in karma so I think a fix will be more helpful 😃

@NullVoxPopuli, first of all, you still should make $root/**/*.js more specific because webpack is processing adapter file

Second, you can’t use {} for files because it breaks karma - https://github.com/NullVoxPopuli/react-vs-ember/blob/master/testing/react/tests/karma.conf.js#L16

So you can replace it by this:

    files: [
      path.resolve(root, 'tests/**/*.ts'),
      path.resolve(root, 'tests/**/*.tsx'),
      // root + '/src/**/*.ts',
      // root + '/src/**/*.tsx',
      // root + '/tests/**/*.tsx',
      // root + '/tests/**/*.ts',
    ],

It should work
