I'm working on a server for a very large (feature wise) MMO. After some bad experiences with breaking changes that caused bugs weeks down the line, we'd like to add unit/automated/regression tests to our project before we get much father (we've implemented approximately 5% of our requirements).We haven't really used serious tests before (we've done the tutorial check-division-by-zero testing) so I thought I'd locate some guides for developing client-server test solutions. I was not able to find anything of much relevance. How should I deal with testing the following aspects of a typical server?Testing the client-server communication (API can be broken down into parsing, handling and sending stages)Testing changes to an SQL databaseTesting security measuresTesting around security measures (ie, making sure our tests don't trip our own security code)Testing timed eventsIn case it's relevant, our language is C#, .Net 4.5
