If a mock's assert_called_once_with method is misspelled (e.g. asert_called_once_with) then the test will appear as passing. Therefore, this commit removes all instances of assert_called_once_with calls and replaces them with two assertions:
self.assertEqual(mock.call_count, 1)
self.assertEqual(mock.call_args, mock.call(call_args))
* Relaxes the configuration options for influxdb
By default influxdb allows unauthenticated access
Home Assistant required at least username and password to be present to properly submit data to influxdb
* Removes unused import of 'copy'
The copy module was used only in the removed test case responsible for testing the missing keys
* Updates InfluxDB config schema to require user and password
Current InfluxDB (v 1.0) can work without any authentication, but when authentication is enabled both username and password should be set.
* Removes extra white space in test_influxdb.py
