SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill automates the creation of comprehensive test suites for APIs, significantly reducing the manual effort and time required for API testing and ensuring robust quality assurance.

Core Features & Use Cases

  • Automated Route Detection: Scans various framework codebases (Next.js, Express, FastAPI, Django) to identify all API endpoints.
  • Comprehensive Test Generation: Creates tests for authentication, input validation, error codes, pagination, file uploads, and rate limiting.
  • Framework Agnostic Output: Generates ready-to-run test files for Vitest+Supertest (Node.js) or Pytest+httpx (Python).
  • Use Case: When a new API endpoint is developed, use this Skill to instantly generate a baseline test suite, ensuring all critical aspects are covered from the start, adhering to TDD principles.

Quick Start

Use the api-test-suite-builder skill to generate tests for the /users endpoint in a FastAPI application.

FAQPage Schema
How do I auto-generate API tests for FastAPI and Express routes?

To auto-generate API tests, use a scanner that detects route definitions across frameworks like FastAPI and Express, then outputs ready-to-run test suites covering authentication, validation, and error codes using Pytest or Vitest.

What types of API tests are typically generated for backend development?

Generated API test suites typically cover authentication, input validation, error codes, pagination, file uploads, and rate limiting to ensure comprehensive quality assurance for backend development.

Can I generate Vitest and Supertest test suites for Next.js APIs?

Yes, you can generate Vitest and Supertest test suites for Next.js APIs. The scanner detects Next.js route definitions and produces compatible test files to validate endpoints.

Does automated test generation work with both Python and Node.js frameworks?

Automated test generation works with both Python and Node.js frameworks, producing output compatible with Pytest+httpx for Python and Vitest+Supertest for Node.js applications.

How do I create baseline test suites for new API endpoints following TDD?

Create baseline test suites for new API endpoints by scanning route definitions to instantly generate tests covering critical aspects like input validation and rate limiting, adhering to TDD principles from the start.

What are the limitations of automated API test generation for Django?

Automated API test generation for Django scans route definitions to create tests, but may require manual adjustments for complex custom business logic or highly specific integration scenarios not covered by standard route detection.
