From appveyor:

√ ng generate component test\..\my-comp (313ms)
ERR:  { [Error: ENOENT: no such file or directory, uv_chdir] errno: -4058, code: 'ENOENT', syscall: 'uv_chdir' }

Legit?

[Brocco]

Yes, AppVeyor failed because the full test run times out after an hour. The check mark means the test passed. I don't know how to rerun that test, thoughts?

[hansl]

Just restarted it.

Seems like everything is green. LGTM! Please rebase and submit.

Ran npm test manually, since appveyor got stuck.
