SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill automates the creation of realistic mock API services, enabling parallel development, efficient testing, and robust demo environments without relying on live backend systems.

Core Features & Use Cases

  • API Mocking: Design and implement mock services that simulate real API behavior, including dynamic responses, state management, and scenario-based testing.
  • Contract Testing: Generate mocks directly from API contracts (like OpenAPI) and validate responses against them.
  • Performance Simulation: Simulate latency, throughput, and error rates for performance and load testing.
  • Use Case: A frontend team needs to develop a new feature that interacts with a payment gateway API. They use this Skill to create a mock of the payment gateway, allowing them to test their feature thoroughly even before the actual API is ready.

Quick Start

Use the api-testing-observability-api-mock skill to create a mock API for the endpoint '/users/{id}' that returns a 200 status code with a JSON body containing 'id', 'name', and 'email'.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a mock API for frontend development when the backend is not ready?▼

Create mock APIs to simulate real backend behavior using dynamic response generation and scenario management. This allows frontend development and testing to proceed in parallel without relying on live backend systems.

Can I generate mock APIs directly from an OpenAPI contract?▼

Yes, contract-based mocking supports generating mocks directly from API contracts like OpenAPI. It also validates responses against the contract schema using libraries such as jsonschema to ensure consistency.

What Python libraries do I need to set up a mock API service?▼

Setting up a mock API service requires Python libraries including FastAPI for web serving, Faker for data generation, and jsonschema for contract validation. These dependencies enable dynamic responses and schema enforcement.

How do I simulate API latency and error rates for performance testing?▼

Simulate API latency, throughput, and error rates to conduct performance and load testing. This helps evaluate how your application handles slow responses and network unreliability without hitting production systems.

What is the best way to manage different testing scenarios with mock APIs?▼

Scenario management in mock APIs allows you to define and switch between different response states dynamically. This enables thorough testing of various application flows, error conditions, and edge cases within a single mock service.
