Usage: showcase test <slug> [options]

Run probe tests against a showcase service (via Docker containers).

Options:
  --d6             Run D6 (e2e-full) probes only (via fleet control-plane)
  --d5             Run D5 (e2e-deep) probes only (via fleet control-plane)
  --d4             Run D4 probes only
  --direct         Legacy/debug: run d5/d6 via the in-process driver
                   instead of the fleet control-plane (producer->queue->worker)
  --smoke          Run smoke probes only
  --verbose        Verbose test output
  --headed         Run Playwright in headed (visible) mode
  --repeat <n>     Run N times
  --keep           Don't stop auto-started packages after test; with --isolate,
                   also leaves the isolated stack standing (teardown command
                   printed at exit). A kept stack left running with no owner is
                   auto-reaped after its keep TTL (default 4h); run
                   'showcase reap' to tear it down sooner.
  --live           Write results to PocketBase for dashboard
  --rebuild        Force Docker rebuild before running
  --cycle          On failure, auto-dump aimock logs from the test window
  --isolate [name] Run in an isolated compose project with offset ports
                   (default name: showcase-iso<slot>). Allows parallel test runs.
                   The optional name may appear before OR after the <slug>.
  --isolate=<N>    Sugar form: pin the isolation slot to N (equivalent to
                   prefixing SHOWCASE_ISO_SLOT=<N>). 1≤N≤ISOLATE_MAX_SLOT.
  --isolate=<name> Sugar form: explicit isolate name (non-numeric), equivalent
                   to '--isolate <name>'. A bare '--isolate=' is rejected.

Examples:
  showcase test mastra --d6 --verbose         # D6 probes (full matrix) with verbose output
  showcase test mastra --d5 --verbose         # D5 probes with verbose output
  showcase test mastra --d5 --cycle           # D5 + aimock logs on failure
  showcase test langgraph-python              # all tests for a slug
  showcase test mastra --d5 --headed          # watch the browser
  showcase test agno --d5 --isolate           # isolated run (auto-named)
  showcase test agno --d5 --isolate d5verify  # isolated with explicit name
  showcase test agno --d5 --isolate=9         # pin to slot 9 (equiv: SHOWCASE_ISO_SLOT=9 ... --isolate)
