   ``TEST_LIST var``
     Make the list of tests available in the variable ``var``, rather than the
     default ``<target>_TESTS``.  This can be useful when the same test
     executable is being used in multiple calls to ``doctest_discover_tests()``.
     Note that this variable is only available in CTest.
 
+  ``JUNIT_OUTPUT_DIR dir``
+    If specified, the parameter is passed along with ``--reporters=junit``
+    and ``--out=`` to the test executable. The actual file name is the same
+    as the test target, including prefix and suffix. This should be used
+    instead of EXTRA_ARGS to avoid race conditions writing the XML result
+    output when using parallel test execution.
