4.7When to Use the Orchestrator Pattern

Best for:

  • Multi-layer testing (UI + API + performance in one run)
  • Feature-level test orchestration (one feature, multiple test types)
  • Centralized reporting across test domains
  • Teams with distinct testing specialties

Risks:

  • The orchestrator becomes a bottleneck if it makes poor delegation decisions
  • Single point of failure: if the orchestrator agent fails, all testing stops
  • Over-engineering: for simple test suites, a single agent is simpler

Mitigation:

  • Always log the delegation rationale for debugging
  • Implement fallback: if a specialist fails, the orchestrator continues with others
  • Set per-specialist timeouts so one slow specialist does not block the report
