# ==== Purpose ====
#
# This test script serves as the functionality testing for the table
# performance_schema.replication_applier_status. Test for ddl and dml
# operations is a part of the perfschema suite. The ddl/dml tests are named:
# 1) ddl_replication_applier_status.test and
# 2) dml_replication_applier_status.test.
#
# The follwing scenarios are tested in this script:
#
#  - Verify that output is same as SSS on a fresh slave.
#  - Verify that the value of this field is correct after STOP SLAVE.
#  - Remaining delay is not tested.
#  - Count_trnsaction is partially tested here making sure it can be queried.
#    More testing in extra/rpl_deadlock.test
