What mocking patterns are supported?

It supports simple mocks, verification-ready mocks, controlled failure injection, the builder pattern for mocks, and full in-memory implementations.

Does it require external mocking crates like mockall?

While it can work with them, it focuses on providing clean, hand-written mock implementations that follow best practices to keep your test suite lightweight and easy to debug.

Can it handle asynchronous Rust code?

Yes, it includes patterns specifically designed for async_trait and Tokio-based testing scenarios common in modern Rust development.

How does this skill help with Rust testing?

It provides standardized patterns for creating mock implementations of traits, allowing you to test business logic without relying on external dependencies like databases or APIs.

セキュリティとテスト

Implements robust testing patterns and mock strategies for Rust applications using trait-based abstractions.

概要

The Rust Mocking Strategy Guide is a specialized skill for Claude Code designed to help developers build testable Rust applications through decoupling and effective mocking. It provides expert guidance on creating mock implementations for external dependencies like databases and HTTP services, specifically focusing on hexagonal architecture and trait-based patterns. By providing templates for simple mocks, verification doubles, and controlled failure simulations, this skill ensures your Rust test suite remains fast, reliable, and independent of real infrastructure while maintaining high code coverage.
