It's not really an issue. I just thought that having the description highlighted might be nice for the students to focus on it. But of course I don't know how difficult it is to actually add something like that.
In my setting the issue came up that I would need to have the description twice (once for the matlab block and once for the python block). Or somehow make it possible for the grader to split off a description and add it to the output independent of the language. But that is of course specific to my setting.
I tried to use the 'Extra template data' field available for each test. From the documentation I wasn't quite sure if this is like 'global extra', i.e. a text field or like 'template params' i.e. a json structure where I can add multiple fields? I guess my question just I be able to write {{ Test.params.description }} in my grader and add { "description": "Super test" } into the extra template data field - I tried that but it didn't work that way.
