# ==== Purpose ====
#
# This test script serves as the functionality testing for
# WL#6120- Change master without stopping Slave threads.
#
# This test script does the following:

#  - Ensure that the behavior does not change for CHANGE MASTER when both the
#    IO and SQL threads are stopped.
#  - We have two types of options- receiver options and applier options under
#    CHANGE MASTER
#    And we have a very simple rule:
#       -  Allow setting receiver options when the receiver is not running,
#       -  Allow setting applier options when the applier is not running,

#    Make sure we stick to the above mentioned rule.

# The follwing scenarios are tested:
#
#  - With both receiver and applier stopped, all CHANGE MASTER options should be
#    allowed.
#  - With receiver stopped and applier running, we should be able to change
#    receiver options.
#      - Setting receiver options should throw the correct error message.
#      - Using an allowed option and a not allowed option should error out.
#  - With applier stopped and receiver running, we should be able to change
#    applier options.
#      - Setting applier options should throw the correct error message.
#      - Using an allowed option and a not allowed option should error out.
