Writing integration tests for REST API endpoints requires enumerating endpoints and methods, verifying happy path and error handling responses, validating request and response schemas, and testing database interactions using standard testing libraries like Vitest or Jest.

A REST API testing strategy should include endpoint coverage planning, happy path and error handling verification, schema validation, authentication and authorization behavior checks, and integration testing across the API lifecycle.

Yes, this API testing approach works with Vitest or Jest. It relies on standard testing libraries and your project configuration to implement tests for REST API endpoints and generate coverage reports.

To test REST API authentication and schema validation, you validate request and response schemas to ensure data integrity, and verify authentication and authorization behavior to ensure secure access controls across your endpoints.
