The OpenTelemetry Demo uses traced-based testing to validate the functionality of the services and the traces they generate.
The trace-based tests will each service and validate the traces they generate and stored in Jaeger, to a known working trace for the same operation.
To run the entire test suite of trace-based tests, run the command:
make run-tracetesting
#or
docker compose run traceBasedTests
To run tests for specific services, pass the name of the service as a parameter (using the folder names located here):
make run-tracetesting SERVICES_TO_TEST="service-1 service-2 ..."
#or
docker compose run traceBasedTests "service-1 service-2 ..."
For instance, if you need to run the tests for ad-service
and
payment-service
, you can run them with:
make run-tracetesting SERVICES_TO_TEST="ad-service payment-service"
