UNIT TEST CONSIDERATION

  1. Unit testing should be performed for when the build constant FLTINJENA is set to STD_ON in order to enable core functionality of this module. This will have to be done by manually altering FltInj.h to change the value of this #define.

  2. The SigPah_Arg signal of the FltInj_f32 server runnable has a special unit test consideration (MIL, SIL, PIL) that the range called out in the data dictionary should only be used for defining "input" vectors, and the range check that is normal done on the "output" is skipped in this special instance. (This second point is copied from the FDD).
