Error 'module' object has no attribute when test download

I tried with already finished extractor like StreamangoIE and StreamcloudIE. Both crashed with the same error.

MacBook-Pro:test MinhDV$ python test_download.py streamango.Streamango

Same issues in topic #13266

It's TestDownload.test_Streamango not streamango.Streamango.
