Testing

Everything runs against the real stack (DB, S3, Kubernetes) via Docker Compose. No mocks.

# start services, then run the whole suite
docker compose -f compose.yaml -f compose.test.yaml up -d db s3
docker compose -f compose.yaml -f compose.test.yaml run --rm api

# one package
docker compose -f compose.yaml -f compose.test.yaml run --rm api go test -v ./app/meta/...

# E2E, behind a build tag
docker compose -f compose.yaml -f compose.test.yaml run --rm api go test -v -tags=e2e .

Layout

Integration (app/*/*_test.go) against a real database, S3 and Kubernetes.
E2E (main_test.go) full system scenarios.

Helpers per package:

testDB(t) database connection with cleanup (app/api, app/meta, app/db)
testWorkflowClient(t) real Argo Workflows client (app/api)
testutil.TestDBURL() reads SCALEODM_DATABASE_URL

func TestFeature(t *testing.T) {
    db, cleanup := testDB(t)
    defer cleanup()

    store := meta.NewStore(db)
    // ...
}

Test data

Database: SCALEODM_DATABASE_URL, same var as prod. Tests clean up after themselves.
S3: AWS_S3_ENDPOINT, the RustFS instance in the compose stack.
Kubernetes: needs a real cluster (Talos) with Argo Workflows installed.

When something breaks

docker compose -f compose.yaml -f compose.test.yaml ps           # services up?
psql postgres://odm:odm@localhost:31101/scaleodm?sslmode=disable # DB reachable?
kubectl get pods -n argo                                         # Argo alive?
