Achu, The normal way people deal with this is to separate the fetching of a specific real page from the logic that parses it. The condition you are interested in testing is part of the logic that parses the page. By making it a separate object that does only the parsing, you can test it with many example JSON documents of various sizes and various contents. You can tightly control what the example data is.
