migrate-to-shoehorn

Replace unsafe TypeScript as type assertions by mapping valid partial data casts to fromPartial and intentionally incorrect double-as casts to fromAny using @total-typescript/shoehorn. This migration preserves type safety while allowing minimal test payloads.

In TypeScript testing, fromPartial supplies valid partial data that remains type-correct, whereas fromAny is used for intentionally incorrect test data. Both helpers replace unsafe as type assertions to maintain type checking while improving developer ergonomics.

To migrate large test fixtures to pass only required properties in TypeScript, replace full object as Type casts with fromPartial. This allows unit and integration tests to supply minimal, partial payloads that still satisfy parameter types without faking the entire object.

Yes, installing @total-typescript/shoehorn is required to use fromPartial and fromAny. These helpers replace unsafe as unknown as Type patterns, ensuring your TypeScript test data type-checks correctly after migration.

You should replace as unknown as Type in TypeScript tests with the fromAny helper from @total-typescript/shoehorn. This approach preserves the ability to supply intentionally incorrect test data while maintaining type safety and developer ergonomics.
