概要
This skill empowers developers to master the dual nature of TypeScript testing by seamlessly integrating runtime behavior verification with sophisticated type-level assertions. It offers structured patterns for using Vitest alongside the inferred-types library, ensuring that complex generic types and inferred signatures are just as validated as executable logic. By enforcing a unified testing architecture, it helps eliminate common pitfalls like separated test blocks and incorrect assertion patterns, ultimately fostering a more resilient and type-safe codebase.
