api-testing

API testing automates endpoint and middleware validation to prevent regressions. Using Vitest, you write unit and integration tests under apps/web/__tests__ to verify request/response shapes, status codes, and error handling.

You validate API request and response shapes in Vitest by writing integration tests that assert expected status codes and payload structures. This Skill organizes tests under apps/web/__tests__ with reusable helpers and mock utilities for comprehensive validation.

Yes, API testing with Vitest supports testing middleware and error handling. It automates comprehensive validation for integrations, allowing you to verify health checks, parameter validation, and error responses across your web services.

The best way to structure API tests is organizing them under apps/web/__tests__ with reusable helpers and mock utilities. This Vitest-based structure covers health checks, parameter validation, and error responses for new API routes.

Mock utilities are needed for API endpoint testing to isolate routes and middleware during validation. They allow you to simulate request/response scenarios and verify error handling without relying on live external integrations.

Yes, you can use Vitest for both unit and integration testing of API functionality. It serves as the test runner for validating API routes, middleware, and utilities to ensure reliability across services.
