SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill ensures that the contract between two systems is adhered to, not the internal implementation, reducing the risk of breakage due to internal changes.

Core Features & Use Cases

Contract Boundary Testing: Ensures that both systems agree on the contract's terms, allowing internal changes without affecting the other system.
Edge Case Coverage: Tests for the documented error responses, pagination bounds, and versioning to cover the contract's edges.
Consumer Validation: Promotes testing against the real contract to avoid drifting from expected behavior.
Schema Consistency: Ensures a single source of truth for the schema, validating against it for both sides.

Quick Start

Run the contract-test skill to validate the API endpoint 'https://api.example.com/data' against the provided schema file 'schema.yaml'.

FAQPage Schema

What is contract testing and how does it verify system integration?▼

Contract testing verifies the agreed-upon terms between two systems rather than internal implementation details, ensuring both sides validate against a common schema to prevent breakage from internal changes.

How do I validate an API endpoint against a shared schema?▼

You can validate an API endpoint against a shared schema by running a contract test that checks the endpoint's responses against the agreed schema file, ensuring schema consistency across both systems.

Does contract testing cover edge cases like error responses and pagination bounds?▼

Contract testing covers edge cases by testing documented error responses, pagination bounds, and versioning to ensure both systems handle the contract's boundaries consistently.

Can I test service integrations without coupling to internal implementation details?▼

Yes, contract testing validates the contract boundary between systems, allowing internal changes without affecting the other system, promoting consumer validation against the real contract to avoid drift.

Why should I use contract testing instead of testing implementation details directly?▼

Contract testing reduces the risk of breakage from internal changes by ensuring both systems agree on the contract's terms, maintaining a single source of truth for the schema rather than testing implementation.

What do I need to start contract testing for my API?▼

To start contract testing, you need an API endpoint URL and a schema file defining the agreed-upon terms, then run the contract test to validate the endpoint against the provided schema.
