A collection of some basic tests for the Arduino library.

Extensive coverage is a bit difficult, since a positive test involves actually
|
|
connecting and issuing commands to a live Arduino, hosting any hardware
|
|
required to test a particular function. But a core of basic communication tests
|
|
should at least be maintained here.
