These classes most likely still need tests.  Once you've made tests for a
class, please remove from this list.

NOTE: This list is by no means exhaustive, nor is there a guarantee that it
is possible to create a test for a given class.  If you think it's not possible
to create a test for a given class in this list, please remove that class from
this list and explain in the commit message why it is not possible to create
a test for that class.
