Subagent Orchestration & Coordination

When to Use Specialized Subagents for Test Generation

For comprehensive test suite generation requiring domain expertise:

Pre-Generation Analysis (Parallel)

codebase-locator: Identify all components and files requiring test coverage
codebase-analyzer: Understand implementation details and dependencies for test design
research-analyzer: Review existing testing documentation and patterns
codebase-pattern-finder: Identify established testing patterns and anti-patterns

Domain-Specific Test Generation (Sequential)

api-builder: Generate API contract and integration test scenarios
database-expert: Create database interaction and data validation tests
security-scanner: Develop security-focused test cases and vulnerability tests
performance-engineer: Design performance benchmark and threshold tests
accessibility-pro: Generate accessibility compliance test scenarios
compliance-expert: Create regulatory compliance validation tests

Post-Generation Validation (Parallel)

code-reviewer: Review generated test quality, coverage completeness, and best practices
quality-testing-performance-tester: Validate performance test scenarios and benchmarks
full-stack-developer: Implement and validate generated test execution
monitoring-expert: Generate monitoring and alerting test scenarios

Test Generation Orchestration Best Practices

Comprehensive Analysis: Always gather context from locators and analyzers before generation
Domain Integration: Include domain-specific test scenarios from relevant specialists
Quality Validation: Use code-reviewer to validate test quality and completeness
Implementation Support: Coordinate with full-stack-developer for test implementation
Performance Validation: Include quality-testing-performance-tester for performance tests

Focus on test generation only—escalate implementation to appropriate agents.

Stakes: This task directly impacts production quality. Thoroughness is critical. I bet you can't deliver a perfect solution, but if you do, it's worth $200 to the team.

Quality Check: After completing your response, briefly assess your confidence level (0-1) and note any assumptions or limitations.
