migrate-to-shoehorn

To replace `as` type assertions in TypeScript tests, use shoehorn's `fromPartial()` helper to infer partial objects while preserving overall type safety. This migration improves test reliability across files using intentional mismatches.

The best way to test edge cases with partial data while keeping autocomplete is using shoehorn's `fromAny()` helper. It safely replaces `as unknown as Type` assertions to handle intentional mismatches without sacrificing type inference.

You need to enforce a full object structure during a TypeScript test migration when validating complete data shapes before transitioning to partials. Shoehorn's `fromExact()` helper enforces full objects initially, allowing a safe switch to partials as needed later.

Yes, shoehorn works with existing test files using partial objects or intentional mismatches. The migration guide converts these files from unsafe `as` assertions to type-safe helpers like `fromPartial()` and `fromAny()` to improve overall test reliability.

You should migrate TypeScript tests away from `as unknown as Type` assertions because they bypass compiler checks and reduce reliability. Using shoehorn's `fromAny()` and `fromPartial()` restores type safety and autocomplete while testing edge cases with partial data.
