ReadonlyDeep: add test for function or method returning an object? · sindresorhus/type-fest#826

2024-03-07T15:46:03.000Z

Reading through the [`ReadonlyDeep type`](https://github.com/sindresorhus/type-fest/blob/HEAD/source/readonly-deep.d.ts) and [`its tests`](https://github.com/sindresorhus/type-fest/blob/main/test-d/readonly-deep.ts), I can't tell if `ReadonlyDeep Map>()` would return a `Map` or a `ReadonlyDeep `. The tests just don't cover that sort of case.

Reading through the ReadonlyDeep type and its tests, I can't tell if ReadonlyDeep<() => Map>() would return a Map or a ReadonlyDeep<Map>. The tests just don't cover that sort of case.

研究方向: Examine the existing test file at test d/readonly deep.ts to understand the test pattern. Review the ReadonlyDeep type definition at source/readonly deep.d.ts to determine how it handles function return types. The goal is to add a test case for `ReadonlyDeep<() => Map>` and verify the expected behavior by checking if the result is a Map or ReadonlyDeep<Map>. Refer to existing tests for structure and assertions.
