What is missing?

[killerboot]

There was a fix to this test in 28e4df5 which may affect your results.
The tests are always run in suits like AllUnitTestsSuite, AppContext01TestSuite and etc. See https://github.com/Alfresco/alfresco-repository/blob/master/.travis.yml .
Unfortunately the tests will fail if all of them will be run in one batch due to test data or config cleanup issues.

Please reopen if it is still an issue.
