The OP didn't mention all he included in "the mess" but just taking exception handling, you need a handler for each potential exception, which leads to duplicate test assertion logic or translating the emission of a particular exception into a numeric/enumerated value that later conditional logic decodes. Either way, that quickly becomes a mess.
