fixtures.ts: auto-applied login fixture — visits /login?local to skip OIDC
auto-redirect, fills username/password via label-matcher, clicks 'Sign in',
then selects the 'default' env so alerting hooks enable (useSelectedEnv gate).
Override via E2E_ADMIN_USER + E2E_ADMIN_PASS.
alerting.spec.ts: 4 tests against the full docker-compose stack:
- sidebar Alerts accordion → /alerts/inbox
- 5-step wizard: defaults-only create + row delete (unique timestamp name
avoids strict-mode collisions with leftover rules)
- CMD-K palette via SearchTrigger click (deterministic; Ctrl+K via keyboard
is flaky when the canvas doesn't have focus)
- silence matcher-based create + end-early
DS FormField renders labels as generics (not htmlFor-wired), so inputs are
targeted by placeholder or label-proximity locators instead of getByLabel.
Does not exercise fire→ack→clear; that's covered backend-side by
AlertingFullLifecycleIT (Plan 02). UI E2E for that path would need event
injection into ClickHouse, out of scope for this smoke.
Prepares for Plan 03 unit tests (MustacheEditor, NotificationBell, wizard step
validation). jsdom environment + jest-dom matchers + canary test verifies the
wiring.
