What problem does it solve?

This Skill solves the problem of unreliable, slow, and hard-to-debug tests by guiding you to write truly hermetic unit tests that isolate a single handler or function.

Core Features & Use Cases

• Hermetic unit testing: ensures tests use no network, no database, and no filesystem while validating handler behavior in isolation.
• Generated mock injection: uses generated mocks for every contract dependency so you never construct real clients in unit tests.
• Correct error-code verification: validates Connect error codes for failure paths so behavior is asserted precisely.
• Use case: when you’re building a service handler (for example, CreateUser or GetOrder), you can confidently cover edge cases like duplicate inputs or not-found scenarios without flakiness.

Quick Start

Use the unit skill to add or run handler-level unit tests that verify both success and specific Connect error codes while staying fully hermetic.
