created proper test flow and controls
added get community to test serialization as creation method
returns no body
added exception basic exception handling

there are only 4 type of things to handle:
* xml
* json
* EofSensorInputStream (returned when there's no content or on error)
* exceptions

all should have no problems in being deserialized
added a flag to check wheter the test is at its first run

this may conflict if we test with multiple endpoint someday in the
future
