# Purpose:
#       To test the FaultConsumer
#
# Process being tested:
#       Fault_Consumer
#           implements FaultConsumer interface.
# Processes used in test:
#       FT_Replica
#           implements TestReplica interface.
#           implements PullMonitorable.
#       Fault_Detector
#         implements FaultDetectorFactory interface
#         implements PullMonitorable interface
#       FT_Client
#           client for TestReplica interface.
#           client for PullMonitorable.
#       Fault_Notifier
#           implements the FaultNotifier interface.
#           propagates fault reports to the FaultConsumer.
#
# Test Scenario (***Test: marks behavior being tested):
#   Phase 1:
#     Start two FT_Replicas
#       FT_Replicas write TestReplica IORs (FR#1 and FR#2) to files
#     Start the Fault_Detector
#       Fault_Detector writes its IOR (FDF) to a file
#     Start the Fault_Notifier
#       Fault_Notifier writes its IOR (FN) to a file.
#     Start the Fault_Consumer
#       Subscribes to the Fault_Notifier for fault reports.
#   Phase 2:
#     Wait for IORs: FR#1, FR#2, FDF, and FN
#     Start the StubAnalyzer giving it IORS: FR#1, FR#2 FDF, FN
#      StubAnalyzer calls FDF to create a FaultDetector
#       for each Replica.
#      StubAnalyzer subscribes to Fault_Notifier
#      StubAnalyzer writes dummy message(READY) to a file.
#   Phase 3:
#     Wait for READY
#     Start FT_Client giving it IORS: FR#1 and FR#2. [1]
#       FT_Client interacts with FR#1.
#       FT_Client asks FR#1 to fault.  It does so.
#       FT_Client notices fault and switches to FR#2. [1]
#       FD#1 notices fault and notifies Fault_Notifier
#       FD#1 terminates
#       ***Test: Fault_Notifier forwards notification to StubAnalyzer
#       StubAnalyzer prints notification.
#       FT_Client interacts with FR#2.
#       FT_Client asks FR#2 to shut down.
#       FT_Client shuts down.
#       FD#2 notices FR2 is gone, interprets this
#         as a fault, and sends notification to Fault_Notifier
#       FD#2 terminates.
#       ***Test: Fault_Notifier forwards notification to StubAnalyzer
#       StubAnalyzer prints notification.
#     Phase 4: shutting down.
#       All FaultDetectors have terminated so the FaultDetectorFactory
#        honors the "quit-on-idle" option on it's command line and exits.
#       StubAnalyzer compares # fault notifications to # replicas. When
#        they match, it "knows" that the test is over, so it shuts down.
#        As it does so, it disconnects its fault consumers from the FaultNotifier.
#       FaultNotifier notices the last fault consumer disconnecting and exits because
#        the "quit-on-idle" option was specified on the command line.
#     Phase 5: housekeeping
#       Wait for all processes to terminate.
#       Check termination status.
#       Delete temp files.
#
# [1] Client mediated fault tolerance.  These points will
#     change when IOGR support is available.
