How Testability Drives Observability

Explore trace-based testing and its impact on improving observability in a 39-minute conference talk. Learn how to enhance OpenTelemetry tracing data quality and address production issues through practical demonstrations. Discover the process of creating trace-based tests, which offer deeper insights than traditional black box testing by leveraging rich trace information. Watch a live coding exercise that showcases how trace-based testing increases test coverage and improves traceability. Examine a failure scenario and its associated trace, then follow along as the speaker develops a trace-based test to cover the scenario while enhancing OpenTelemetry instrumentation. Gain insights into how this approach not only creates more comprehensive tests but also enhances trace quality, ultimately leading to improved system observability.
