To run the integration test you need to set your ENV var SUBSTREAMS_INTEGRATION_TESTS=true. By default the tracing is disabled in integration tests. To enable the tracing following the steps below

Note: I'm getting an error with jaeger

1. Run a tracing client (jaeger, zipkin...). Don't run both, choose one

# running zipkin
docker run -p 9411:9411 openzipkin/zipkin
# running zipkin jaeger
docker run --name jaeger \
  -e COLLECTOR_OTLP_ENABLED=true \
  -p 16686:16686 \
  -p 4317:4317 \
  -p 4318:4318 \
  jaegertracing/all-in-one:1.35

1. Run test with ENV var

• Zipkin: SF_TRACING=zipkin://localhost:9411?scheme=http
• Jaeger: SF_TRACING=jaeger://localhost:4317?scheme=http

1. Wait a few seconds after the test is complete to see the trace in your browser:
   • Zipkin: http://localhost:9411/
   • Jaeger: http://localhost:16686/
