+# ==== Purpose ====
+#
+# This test script serves as the functionality testing for the table
+# performance_schema.replication_applier_status_by_coordinator. Test
+# for ddl and dml operations is a part of the perfschema suite.
+# The ddl/dml tests are named:
+# 1) ddl_replication_connection_configuration.test and
+# 2) dml_replication_connection_configuration.test.
+#
+# This test script does the following:
+
+# - Verify that SELECT works for every field in the table.
+# - The SELECT per field produces an output similar to the corresponding field
+# in SHOW SLAVE STATUS(SSS), if there is one.
+# - If there is no matching field in SSS, we resort to other method of testing
+# those fields.
+# - We perform all the testing on connection "slave". On master, the table
+# returns an empty set.
+#
+# The follwing scenarios are tested in this test script:
+#
+# - Test each field in STS on a fresh replication setup.
+# - Change configuration parameters using CHANGE MASTER TO and verify that
+# these changes are seen in SELECTs from PS table.
+# - Verify that, the change in values are correctly shown by the table.
+# - Verify that the values are preserved after STOP SLAVE, thread_id
+# changes to NULL and service_state changes to "Off".
+# - A priliminary test for Multi-threaded slave(MTS) mode.
