api-tests

What problem does it solve?

This Skill streamlines the creation, maintenance, and repair of end-to-end (e2e) tests for NestJS APIs, ensuring robust and reliable application behavior.

Core Features & Use Cases

• Deterministic Test Generation: Creates or updates e2e tests using the project's existing runner (Vitest/Jest) and Supertest.
• Auth Scenario Coverage: Automatically detects and includes JWT authentication scenarios, including login, protected routes, and invalid token handling.
• Bootstrap Parity: Ensures tests mirror the production application's bootstrap behavior for accurate validation and status code assertions.
• Use Case: When a developer needs to add new e2e tests for a recently implemented API endpoint, fix failing tests before a release, or ensure authentication flows are correctly covered.

Quick Start

Implement or update NestJS API end-to-end tests by reusing the repository's existing e2e runner and conventions, mirroring src/main.ts bootstrap behavior in tests, detecting whether JWT auth is configured, adding login/protected-route/invalid-token scenarios when auth exists, and verifying with the repository e2e test command before finalizing.
