Testing Warnings for SafetyRequirement Inter-task communication
Testing warnings are related to the tests in the testing layer and their depedencies.

(SafetyRequirement_96) Inter-task communication is not referencing a test and not all refinements reference a test.

Signals can either be global data objects of local objects on the task stack.
Global signals are the same for everyone while with local signals each task has an own copy which gets synchroized if the signal changes,
