There's another similar issue I noticed just now, namely that it's
impossible to extract the parameters passed to a Parameterized test.

Instead, the index of the parameter array is packed into the test name
in brackets, like this: "testFoo[0]" "testFoo[1]" "testFoo[2]".  This
is true even if the parameters are strings.  There is no way to find
out what the strings are/were.

It would be better if the runner could add metadata (like parameters)
to the Description; the metadata could then be handled/interpreted by
RunListener reporters.
