This code is a simple alarm which uses a remote service to sample a value and then set the alarm on or off depending on the result. This is existing code which is packaged into a jar and used by other applications.
This kata is to review the Alarm class and to refactor this class to make it unit testable.
As part of this, identify the issues which are causing this test to be difficult to test. Can you name the SOLID design principle which is being violated?
