I was thinking it would be good for the test output with -Dderby.tests.trace=true to have the class name as well as the fixture as I think if I had a nickel for every time I grepped for a fixture name to find out what class it is in, I would have a pretty big piggy bank.
It could print the full class name, like this:
org.apache.derbyTesting.functionTests.tests.lang.SimpleTest.testBasicOperations used 844 ms .
or strip off the org.apache.derbyTesting.functionTests for less output like:
tests.lang.SimpleTest.testBugFixes used 6265 ms .
