- Replaces Nuxt Test Utils with @cloudflare/vitest-pool-workers
- Adds structured test organization for API endpoints
- Introduces comprehensive testing patterns and examples
- Implements schema-based test data generation with zod-mock
- Enhances test utilities with proper CF Workers environment
The new testing setup provides better isolation, more realistic worker runtime environment, and improved test data management through structured schemas and generators.
Refactors URL slug case sensitivity implementation:
- Moves case conversion to creation time instead of lookup
