+If the package names in the `testsuite.name` or `testcase.classname` fields do not
+work with your CI system these values can be customized using the
+`--junitfile-testsuite-name`, or `--junitfile-testcase-classname` flags. These flags
+accept the following values:

+* `full` - the full package path (default)
