Startup Presentation: Observability-driven development with OpenTelemetry

Testing large systems with multiple microservices is hard to understand. You need to understand the whole system, all connections, and how the microservices interconnect.

With tracing you get a map of everything which makes your whole system easier to understand.

I want to showcase traditional test-driven development vs the new observability-driven development. I’ll use open-source tools like Tracetest and OpenTelemetry to showcase how to use trace-based testing and enrich integration tests with trace data.
