+  ``REPORTER reporter``
+    Use the specified reporter when running the test case. The reporter will
+    be passed to the Catch executable as ``--reporter reporter``.
+
+  ``OUTPUT_DIR dir``
+    If specified, the parameter is passed along as
+    ``--out dir/<test_name>`` to Catch executable. The actual file name is the
+    same as the test name. This should be used instead of
+    ``EXTRA_ARGS --out foo`` to avoid race conditions writing the result output
+    when using parallel test execution.
+
+  ``OUTPUT_PREFIX prefix``
+    May be used in conjunction with ``OUTPUT_DIR``.
+    If specified, ``prefix`` is added to each output file name, like so

+  ``OUTPUT_SUFFIX suffix``
+    May be used in conjunction with ``OUTPUT_DIR``.
+    If specified, ``suffix`` is added to each output file name, like so
+    ``--out dir/<test_name>suffix``. This can be used to add a file extension to
+    the output e.g. ".xml".
