Test

Test

Quick start

Prefer the repository’s containerized Go toolchain so local Go versions don’t matter.

Unit tests (default)

Run all unit tests:

docker run --rm -v "$PWD":/src -w /src golang:1.25.6-alpine sh -c "go test ./..."

If you only changed a specific area, prefer a narrower command first (faster), e.g.:

docker run --rm -v "$PWD":/src -w /src golang:1.25.6-alpine sh -c "go test ./internal/..."

Integration test (optional; requires Docker)

Run the concurrency integration test (testcontainers):

RUN_INTEGRATION=1 docker run --rm -v "$PWD":/src -w /src golang:1.25.6-alpine sh -c "go test ./... -run TestConcurrentReviewCreates_UpdateAggregates"

When tests fail (workflow)

1. Re-run the smallest reproducer:
   • If only one package fails, re-run go test for that package.
   • If a single test fails, re-run with -run <TestName>.
2. Read the failure output and identify:
   • exact failing test name(s)
   • expected vs actual
   • whether the failure is deterministic or flaky
3. Fix the root cause (not the symptom), then re-run:
   • the failing test(s)
   • the broader package
   • finally go test ./... (unit) and, if relevant, the integration test above

Notes specific to this repo

• Use docker compose up -d --build to start Postgres/Redis/RabbitMQ when you need runtime dependencies, but unit tests should generally not require it.
• Integration tests requiring Docker should be run only when relevant to the change or when explicitly requested.
