Hi, The attached patch fixes the issue in mauve when running the entire test suite with -xmlout fails: $ java Harness -vm /usr/bin/java -xmlout xmloutputfile No tests were run. Possible reasons may be listed below. Did you specify a test that doesn't exist or a folder that contains no tests? The bug seems to be that mauve ignores the -xmlout option and then treats xmloutputfile as the name of the test to run. The patch adds a case in Harness.setupHarness() so that the argument after -xmlout is skipped (it is later checked in RunnerProcess). Cheers, Omair
