Jest-opentelemetry was created out of a pain that @galklm and I felt when working on complex systems with multiple side effects, some of which happen asynchronously. People were changing the code of different services frequently, but weren't always aware of the dependencies across the system. So often, things would break - resulting in us up at 4am debugging the issue and reverting some recent deployments.

Enter OpenTelemetry. Don't worry if you're not familiar with it (although it's the 2nd largest CNCF project!) - it's just a standard protocol for reporting traces, logs and metrics from production services. We realized it's a great way to observe all the side effects as they happen within the system. We can send a request to the system and then validate side-effects using the OpenTelemetry data coming out of the system.
