+# Check starting conditions. This test case assumes that:
+#  - two mysqld-instances are registered;
+#  - the first instance is online;
+#  - the second instance is offline;
+#
+
+SHOW INSTANCES;
+
+#
+# Check 'SHOW INSTANCE OPTIONS' command:
+#  - check that options of both offline and online instances are accessible;
+#  - since configuration of an mysqld-instance contains directories, we should
+#    completely ignore the second column (values) in order to make the test
+#    case produce the same results on different installations;
+#    TODO: ignore values of only directory-specific options.
