Subject [jira] [Created] (CASSANDRA-9105) JMX APIs appear untested
Date Thu, 02 Apr 2015 19:32:55 GMT
Ariel Weisberg created CASSANDRA-9105:

             Summary: JMX APIs appear untested
                 Key: CASSANDRA-9105
             Project: Cassandra
          Issue Type: Test
            Reporter: Ariel Weisberg

Anything supported via JMX is part of the public API of the database.

Node tool uses JMX but doesn't seem to have its own unit test and the dtest
is pretty sparse.

For values returned by JMX for the purposes of reporting we should test as best we can that
we are getting "real" values end to end. Occasionally metrics end up with no values, or values
in the wrong units.

For commands going the other direction they should be exercised. There is probably a lot of
coverage of commands since they may be used when testing the features those commands are a
part of so no need for duplication there.
