It's not as bad as I thought, setContext(context) is only
used in tests - however I find it hard to imagine that we have
nearly 60 tests which require it to be set using setContext
rather than via doExecute(context).

I would still be keen to split src files into test and
production (as per Marc's sugggestion) to make this kind
of thing more obvious. Current IDEs automatically merge
packages for you when viewing things and it would allow
us to gather better metrics and checks from our IDEs and
better distinguish between files which are purely for test
purposes so that they could be removed from some of our jars
in the future if we so desired.
