Since Confluence 2.3, the main Confluence acceptance tests have used RPC to log the start of each test on the server. This is often useful for determining how a server error may have affected a test. Our Selenium and REST tests do not have this logging, since it's currently done by AbstractConfluenceAcceptanceTest. It's really time that we moved it out of ACAT and into the test-support package where it can be easily used by any test class.
