Merge pull request #4 from CarlosManias/headless-testing

Headless testing
externalized basic auth for tests
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
