Yes, exactly it is hard to check the resulting html. Of course you could parse it and check for specific tags and contents, or you could write regular-expressions ... What is more, the actions in SmallWiki 1 are badly designed, since they heavily couple the business logic and the swazoo html generation. Sadly it is almost impossible to test the actions wihout dealing with request/response ... SmallWiki 2 takes a different approach to avoid this problem and thus the actions (actually these are commands following the design patterns book) can be easily tested.
