Should I test private functions using this skill?

The skill follows the best practice of testing only the public interface and behavior, discouraging the direct testing of implementation details or private functions.

How does it handle mocking in Rust?

It promotes a 'mock-minimal' approach, allowing mocks for external services like HTTP requests and databases while discouraging them for internal project logic.

Does this skill help with integration testing?

Yes, it defines specific rules and directory structures for both internal unit tests and external integration tests located in the /tests directory.

Does it support parameterized testing?

Yes, it includes patterns for table-driven tests, allowing you to run multiple test cases through the same logic efficiently.

セキュリティとテスト

Standardizes Rust unit and integration testing workflows by enforcing best practices for mocks, test structures, and the testing pyramid.

This skill provides a comprehensive framework for implementing high-quality tests in Rust projects. It defines specific conventions for in-module testing, strict mock usage—limiting them to external dependencies like APIs and databases—and parameterized tests to ensure code reliability. By following the integrated test pyramid guidelines and focusing on public-facing behavior rather than implementation details, developers can maintain a robust codebase while avoiding common pitfalls like over-mocking or testing private internals.
