What is the best practice for writing unit tests that rely on internet access?
ie. You have a CPAN module which is all about talking to a web service.. So you have unit tests that do just that. What if the system testing it doesn't allow HTTP connections out? The tests will fail.. Should one a) Prompt the user for whether to skip the tests? (I hate this option.. I dislike interactivity in installers) b) Only run the tests if specifically set by AUTHOR_TEST or something, otherwise mock the server? (I dislike this.. means few good tests run for users) c) Try to test if there's a working connection, and silently skip the tests if not? (Risks skipping tests if the connect fails for other reasons than no outbound HTTP allowed) d) ???
