I think we've discussed this and I have suggested to have a separate file for
the metadata parsing tests rather than putting the tests into another file.
However, at that point I didn't realize the possibility of using the same
approach as for most other CMS features: we can make the page use the variables
in the content somehow and then check the rendered pages against "correct"
expected outputs. I think this approach would be preferable in this case because
we would not add any new testing code, only testing data.

Done.
