migrate-to-shoehorn

You can safely refactor 'as' assertions in TypeScript tests by replacing them with 'fromPartial()' and 'fromAny()' alternatives. This approach maintains type safety while allowing partial test data handling.

You should replace 'as' assertions with shoehorn to enforce strict type checking in automated testing environments. Using 'fromPartial()' prevents silent type errors by validating partial data against expected TypeScript types.

Yes, you need the @total-typescript/shoehorn package installed. This Skill directly refactors existing 'as' assertions into the 'fromPartial()' and 'fromAny()' utility functions provided by that specific dependency.

Yes, you can pass partial mock data without breaking type safety by using 'fromPartial()'. This utility allows you to supply only the necessary test properties while ensuring the object remains fully type-checked against the target interface.

The best way to migrate legacy TypeScript tests to type-safe assertions is running an automated refactoring script. This process converts unsafe 'as' type casts into shoehorn's 'fromPartial()' and 'fromAny()' equivalents without breaking existing test logic.
