Integration Tests

Write integration tests that verify interactions across component boundaries.

Test Creation Checklist

Component Interaction

• Test communication between modules through real interfaces
• Verify dependency injection wiring produces correct collaborators
• Check event propagation across component boundaries
• Validate callback and listener invocation order
• Confirm proper lifecycle management between components

API Contract Verification

• Test request/response format compliance with specifications
• Verify HTTP status codes for success, error, and edge cases
• Check header handling (authentication, content-type, caching)
• Validate pagination, filtering, and sorting parameters
• Test versioning and backward compatibility of endpoints
