@robertcv There's an issue with the tests.

Run:

    def test_search_author(self):
        api = twitter.TwitterAPI(self.credentials)
        corpus = api.search_authors(['@OrangeDataMiner'], max_tweets=5)
        self.assertEqual(len(corpus), 5)
        print(corpus)

This should print a corpus of tweets from @OrangeDataMiner. It does not. Looks like credentials might get broken somewhere in between and tweepy defaults to 'hello' query. Or sth. 🤷‍♀️

The problem is due to mocking of the underlying API. Used data is static, you can see it in tweets.json.
