Usage: showcase test <slug> [options]

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

Options:
  --d6             Run D6 (e2e-full) probes only
  --d5             Run D5 (e2e-deep) probes only
  --d4             Run D4 probes only
  --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
  --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: isolate-<PID>). Allows parallel test runs.

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
