What problem does it solve?

This Skill provides patterns for robust API integration testing, solving the challenge of ensuring reliable communication between services and external systems. It enables you to validate API contracts, data flows, and error handling, preventing integration issues in distributed architectures.

Core Features & Use Cases

• HTTP Client Testing: Demonstrates how to use HttpClient and test frameworks to make requests and assert API responses, including status codes and payload structure.
• Test Data Management: Patterns for setting up and tearing down test data for integration tests, ensuring isolated and repeatable test runs.
• Mocking External Dependencies: Guides on mocking or stubbing external services to focus tests on the API under scrutiny, reducing flakiness and increasing speed.
• Contract Testing: Introduces concepts for consumer-driven contract testing to ensure API compatibility between services.
• Use Case: A backend team develops a new API that integrates with a payment gateway. Using this skill, they write integration tests that mock the payment gateway's responses and assert that their API correctly processes transactions and handles various payment scenarios.

Quick Start

Write an integration test for a POST /api/products endpoint, asserting that a new product is successfully created and returns a 201 Created status code.
