test(e2e): real apiRef chain — CDC ↔ authn JWT ↔ snowplow with extras - #8
Merged
Conversation
Adds a kind-based end-to-end test proving the apiRef status source against real
authn and real snowplow (1.1.1), exercising the actual CDC client code:
projected SA token -> authn /serviceaccount/login (TokenReview -> JWT)
-> snowplow /call (Bearer JWT) -> RESTAction resolution
-> request extras echoed back into .api.echo.args
Asserts both static (apiRef.extras: region) and per-instance (compositionName/
Namespace/Id, request-wins) extras round-trip through the authn-issued JWT and
snowplow's resolution. Build-tagged (e2e) so it stays out of the unit suite.
- internal/composition/apiref_kind_e2e_test.go: the env-driven test.
- hack/apiref-e2e/: reproducible harness (run.sh + manifests + README).

A real, kind-based end-to-end test of the apiRef status source against real authn + real snowplow (1.1.1) — not stubs. It exercises the actual CDC client code (`internal/authn`, `internal/snowplow`, `internal/composition.SnowplowAPIResolver`).
Chain proven
```
projected SA token (file)
─ authn.Client.Token ─▶ authn POST /serviceaccount/login (TokenReview → JWT + clientconfig)
─ snowplow.Client.Resolve(Bearer JWT, extras) ─▶ snowplow GET /call (resolves a RESTAction)
─▶ RESTAction echoes the request extras ─▶ .api.echo.args
```
Assertion
Both static extras (`region`, from `apiRef.extras`) and per-instance extras (`compositionName`/`compositionNamespace`/`compositionId`, injected by the resolver, request-wins) round-trip through the authn-issued JWT and snowplow's RESTAction resolution:
`.api.echo.args == {cn: demo-app, cns: apps, cid: uid-e2e-123, region: eu}`
Evidence (from the passing run)
Layout
Requires docker, kind, kubectl, go, and `../authn` + `../snowplow` checkouts. Run: `hack/apiref-e2e/run.sh`.
