# Startup Presentation: Observability-driven development with OpenTelemetry


- **Date:** Friday, Jul 19, 2024
- **Time:** 11:40–11:45 (5 min)
- **Room:** STAGE 8 (120)
- **Event:** World Congress 2024

## Description

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.
