test-migrate-shoehorn

To migrate TypeScript tests from `as` type assertions to shoehorn, you replace unsafe casts with `fromPartial` to supply only necessary fields and `fromAny` to simulate edge-case inputs, increasing type-safety and reducing boilerplate.

The `fromPartial` function in shoehorn is used in testing to supply only the necessary subset of properties for large objects, creating realistic and type-safe test inputs without requiring the entire object structure.

Yes, you need the `@total-typescript/shoehorn` library installed to migrate your test files, as the workflow relies on its `fromPartial` and `fromAny` functions to replace `as` Type assertions and ensure type-safe test inputs.

The best way to safely test invalid inputs in TypeScript without losing type checks is using shoehorn's `fromAny` function, which simulates edge-case or invalid data while maintaining type-safety during test migrations.

Yes, you can use shoehorn to reduce boilerplate when creating test objects with many required properties by using `fromPartial`, which allows you to provide only the subset of properties needed for the specific test case.
