migrate-to-shoehorn

To replace `as` type assertions in TypeScript test files, you can refactor them to use type-safe alternatives from @total-typescript/shoehorn. This process converts unsafe assertions into robust type-safe statements to improve test data handling.

The best way to handle partial test data while maintaining TypeScript type safety is by using @total-typescript/shoehorn. It allows you to pass partial data in tests while preserving strict type checking and avoiding unsafe `as` assertions.

Yes, you need to install and configure @total-typescript/shoehorn before refactoring test assertions. The migration process requires the shoehorn package to be present in your project so it can provide the type-safe alternatives for your tests.

Replacing `as` assertions with shoehorn improves TypeScript tests by eliminating unsafe type casting and enhancing test data handling. This refactoring ensures your test code maintains strict type safety and prevents runtime errors from invalid data shapes.

A limitation when refactoring TypeScript tests to use shoehorn for type safety is that it specifically targets `as` type assertions and requires prior package configuration. It is designed for test file refactoring rather than general application code type safety.
