SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Ensures that different implementations of a protocol or interface behave consistently, preventing regressions and facilitating safe swaps between them.

Core Features & Use Cases

  • Protocol Conformance: Define a single set of tests that any conforming implementation must pass.
  • Implementation Swapping: Safely replace one implementation (e.g., in-memory) with another (e.g., SQLite) knowing the contract is upheld.
  • AI-Generated Code Validation: Verify that AI-generated code adheres to the specified protocol.

Quick Start

Use the test-contract skill to generate contract tests for the DataStore protocol.

Frequently Asked Questions about test-contract

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

FAQPage Schema
How do I test protocol conformance across multiple implementations?▼

Contract testing validates protocol conformance by generating a single test suite from a defined interface to ensure any implementation adheres to the specified behavior. This allows you to safely swap implementations, like replacing an in-memory store with SQLite, without breaking functionality.

What is the best way to verify AI-generated code adheres to an interface contract?▼

Verifying AI-generated code requires generating protocol test suites that validate design by contract principles. By defining a single set of tests, you can automatically check if AI-generated implementations conform to the expected protocol behavior and prevent regressions.

How does contract testing help with safely swapping an in-memory implementation for SQLite?▼

Contract testing facilitates safe implementation swapping by validating protocol conformance across different systems. You generate a single set of tests from a defined contract, ensuring an in-memory implementation and a SQLite implementation behave consistently without regressions.

Do I need specific testing frameworks to generate design by contract test suites?▼

The skill generates protocol and interface test suites without requiring specific external testing dependencies. It operates independently using internal scripts and references to validate design by contract principles for robust software architecture.

When should I use contract testing instead of standard unit tests?▼

Use contract testing instead of standard unit tests when you need to ensure consistent behavior across diverse implementations of the same protocol. It is specifically designed to validate interface conformance for safe implementation swapping and AI-generated code validation.
