FAQPage Schema
How do I write unit tests for a repository layer with mocked Supabase clients?▼

To write integration tests for API endpoints, structure tests to execute endpoint requests and validate responses. This verifies endpoint behavior, request handling, and response codes, ensuring API contracts are met across Splits Network services.

What is the best way to mock external services like Clerk, Stripe, and Resend in Vitest?▼

To create test fixtures for API testing, build structured mock data representing typical endpoint inputs and outputs. This standardizes test scenarios, ensuring consistent API endpoint evaluation and validating response structures across different testing contexts.

When do I need to use integration tests instead of unit tests for my API?▼

Test organization best practices involve following clear file structure and naming conventions for unit, integration, and API tests. This ensures maintainability, establishes defined coverage targets across architectural layers, and avoids common testing anti-patterns.

What are common testing anti-patterns when writing Vitest unit tests for service layers?▼

Common testing anti-patterns when writing Vitest unit tests include over-mocking service layers and creating brittle test fixtures. Following established testing patterns prevents these issues, ensuring your mocked Supabase clients and API tests remain robust and maintainable.
