Commit Message

Power, Ciara Aug. 23, 2018, 12:08 p.m. UTC
This patch adds all tests for the Telemetry API.
The tests added include a parser test, selftest, and socket
messaging tests.

The parser tests pass valid and invalid messages to the parser
to ensure the correct return values are received.
The selftest tests basic functions in the Telemetry API such as
registering, unregistering, and initialisation.
The socket messaging tests pass messages through the socket and
validates the return message, to ensure the Telemetry API is
responding correctly.
