FAQPage Schema

How do I migrate TypeScript test assertions from as to shoehorn?▼

The shoehorn fromPartial helper replaces as type assertions in TypeScript test files to provide safe partial data handling and preserve autocomplete, avoiding production-style types in tests.

Can I use shoehorn fromPartial to replace as unknown as in unit tests?▼

You can use shoehorn fromAny to replace as unknown as Type in TypeScript unit tests to inject intentionally wrong data while preserving autocomplete, whereas fromPartial handles standard as assertions for safe partial data.

Do I need shoehorn installed before migrating test files?▼

Yes, the migration workflow requires @total-typescript/shoehorn to be installed in your project before replacing as assertions with fromPartial or fromAny helpers and updating imports.

What's the best way to replace as type assertions in TypeScript integration tests?▼

The best way to replace as type assertions in TypeScript integration tests is using shoehorn's fromPartial helper to enforce safe partial data guards and avoid production-style types in test suites.

Why use shoehorn instead of as assertions in TypeScript unit tests?▼

Using shoehorn instead of as assertions in TypeScript unit tests enables safer partial data handling and prevents production-style types from leaking into tests, replacing unsafe casts with fromPartial and fromAny helpers.
