5 # Note: test cases should never call SHOW SLAVE STATUS directly,
6 # because that outputs more information to the query log than what is
7 # needed for the property that is being tested. That would cause
8 # maintenance problems, because (1) it is hard for a human to
9 # understand what property is being tested; (2) the output of many of
10 # the fields is non-deterministic (e.g., Slave_IO_State) or changes
11 # frequently (e.g., binlog positions).
13 # Instead, what you want most of the time is to source one of the
16 # include/check_slave_no_error.inc
17 # Assert that Slave_SQL_Errno = Slave_IO_Errno = 0.
19 # include/check_slave_is_running.inc
20 # Assert that Slave_IO_Running = Slave_SQL_Running = 'Yes'.
