High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I convert TypeScript test assertions from 'as' to type-safe alternatives?▼

You can convert TypeScript test assertions from 'as' to type-safe alternatives by running the migrate-to-shoehorn skill, which automatically transforms them into Shoehorn's fromPartial() and fromAny() functions. This enhances test code maintainability and prevents type-related bugs.

What is the best way to replace 'as' assertions in my test suite with partial data support?▼

The best way to replace 'as' assertions with partial data support is using @total-typescript/shoehorn. This skill automates the test refactoring process, converting unsafe assertions into type-safe alternatives that provide robust type checking and partial data handling.

Does @total-typescript/shoehorn work for automated test refactoring in TypeScript?▼

Yes, @total-typescript/shoehorn works for automated test refactoring in TypeScript. The migrate-to-shoehorn script executes this refactoring by converting 'as' type assertions to fromPartial() and fromAny() functions, ensuring type safety during test suite maintenance.

Why should I migrate my TypeScript test assertions away from 'as'?▼

You should migrate TypeScript test assertions away from 'as' to improve code quality and prevent type-related bugs. Using Shoehorn's type-safe alternatives provides better type checking and partial data support, which enhances overall test code readability and maintainability.

What are the limitations of using Shoehorn for test assertion conversion?▼

The limitations of using Shoehorn for test assertion conversion relate to its specific scope: it is designed exclusively for migrating 'as' assertions to fromPartial() and fromAny() within test files. It requires the @total-typescript/shoehorn dependency to function correctly.
