Event simulation as part of software testing?

Question

I’m currently brainstorming ideas for testing what is essentially an event-sourced/micro services architecture and one idea I’ve came across is event simulation.

I’ve used a discrete event simulation test framework in the past for modelling factory systems but I’m curious about any (such as MCMC) and all event simulation techniques you’ve used as part of your test strategy.

• have you been able to apply this to realistically performance test your platform?
• Have you been able to simulate E2E testing without re-deploying services?
• Have you been able to replicate real scenarios that cross service boundaries?
• Check impact on config changes before they hit prod?

Any help appreciated!
