When trying to pass a ComputerConnector into configRoundtrip(C before), the test fails with a 404 Not Found error when trying to load self/computerConnectorTester/configure. This seems to be because there is no configure.jelly in src/main/resources/org/jvnet/hudson/test/JenkinsComputerConnectorTester. HudsonTestCase still works for the equivalent method, but uses ComputerConnectorTester, so a suitable fix should be to copying the contents of src/main/resources/org/jvnet/hudson/test/ComputerConnectorTester in to src/main/resources/org/jvnet/hudson/test/JenkinsComputerConnectorTester.
