For backend we test with a load testing bot, but we don't do it every commit, just after making larger changes to the backend. I would like to test more, and I'm actually working on better automation for load testing at the moment so that it's easier for us to run them.

Testing lockstep was quite an endeavour. The approach I used was to add a very verbose log to the client and the server which logs basically every gameplay relevant decision. That includes moving a single unit, updating a stat, etc.

Then every time a line is logged, we update a hash, and then send the hash to the client. The client, being in lockstep, should be able to come up with the same hash. If the hash is different, then the client and server both break and we can then analyse the state and see what is different.

As we discovered issues, we added more and more log lines and fixed bugs until everything ran perfectly the same on the client and server.
