This is painful when tests are run by hand, but also buy a buildbot
for instance, because if the tests are slow you have much worse
granularity for the reports.

Also because you have to know how the fixtures work to understand the
tests. I'd rather have something a bit more verbose with explicit
instantiation of fake tools than having to hunt in 3 base classes
what methods are called, when debugging a test.
