Contract Test Generator Skill
Generates contract tests for API migrations, supporting consumer-driven contracts, provider verification, and breaking change detection.
Purpose
Enable API contract testing for:
- Consumer contract generation
- Provider verification
- Schema validation
- Breaking change detection
- Mock server generation
Capabilities
1. Consumer Contract Generation
- Generate from API usage
- Extract from tests
- Build from specs
- Support multiple formats
2. Provider Verification
- Verify against contracts
- Test all consumers
- Check compatibility
- Document failures
3. Schema Validation
- Validate request schemas
- Check response schemas
- Verify data types
- Enforce constraints
4. Breaking Change Detection
- Detect field removals
- Find type changes
- Identify required additions
- Flag compatibility issues
5. Mock Server Generation
- Generate from contracts
- Support stub responses
- Handle scenarios
- Enable development isolation
6. Contract Versioning
- Track contract versions
- Manage compatibility
- Support migrations
- Document changes
