What problem does it solve? TypeScript tests often rely on as type assertions to fake large objects, which requires manually specifying target types, faking every property, and using awkward double assertions like as unknown as Type for intentionally wrong data. This Skill replaces those assertions with type-safe partial mocks from @total-typescript/shoehorn. ## Core Features & Use Cases - Partial test data: Use fromPartial() to pass only the properties a test cares about while keeping TypeScript satisfied. - Intentionally wrong data: Use fromAny() to replace as unknown as Type when testing error paths with invalid data, while retaining autocomplete. - Guided migration workflow: Locate as assertions in test files via grep, convert each pattern, add imports, and verify with the type checker. - Use Case: A test only needs body.id from a Request type with 20+ properties. Instead of faking the entire object, wrap { body: { id: "123" } } in fromPartial() and pass it directly. ## Quick Start Ask the assistant to migrate the as type assertions in your test files to @total-typescript/shoehorn using fromPartial and fromAny.
