Integration tests

This directory contains Prometheus, Tempo and Loki API integration tests.

Docker is required to run.

Getting traces from tests for debugging

Run a local Jaeger instance:

docker run --rm -d --name jaeger -p 16686:16686 -p 4317:4317 jaegertracing/all-in-one:latest

Run wanted test with E2E_TRACES_EXPORTER:

E2E_TRACES_EXPORTER='localhost:4317' E2E='1' go test -v -run "TestCH/QueryRange" ./integration/prome2e

Open Jaeger UI http://localhost:16686/.
