Well, for this particular class maybe it was. But I am sure it is easy to
unit test a lot of other code this way.

Could you elaborate on that, please?

I am not very fond of this approach. First of all I would like to run by
tests as part of the build process. I would not like to have to start
MonoDevelop to be able to run my unit tests. Secondly it might be hard to
test the internals of a class using only some public API.
