Easy for me to say in retrospect, but IMO this is a textbook example of where you should reach for fuzz testing; it’s basically protocol parsing, you have a well-known text format upstream and you need to ensure your system can parse all well-formed protocol messages and at very least not crash if a given message is invalid in your own system. Similarly with a message queue, handling dead letters is textbook stuff, and you must have system tests to verify that poison pills do not break your queue. I did not think the author was setting unreasonable expectations for the a priori testing regime. These are common best practices.
