+## toMatchObjectType
+
+- **Type:** `() => void`
+
+This matcher performs a strict check on object types, ensuring that the expected type matches the provided object type. It's stricter than [`toExtend`](#toextend) and is the recommended choice when working with object types as it's more likely to catch issues like readonly properties.
+
+```ts
+import { expectTypeOf } from 'vitest'
+
+expectTypeOf({ a: 1, b: 2 }).toMatchObjectType<{ a: number }>() // preferred
+expectTypeOf({ a: 1, b: 2 }).toExtend<{ a: number }>() // works but less strict
+
+// Supports nested object checking
+const user = {
+  name: 'John',
+  address: { city: 'New York', zip: '10001' }

+
+::: warning
+This matcher only works with plain object types. It will fail for union types and other complex types. For those cases, use [`toExtend`](#toextend) instead.

+<<<<<<< HEAD
 当类型不匹配时，`.toEqualTypeOf` 和 `.toMatchTypeOf`会使用一种特殊的辅助类型来生成尽可能可操作的错误信息。但要理解它们还有一些细微差别。由于断言是 "流畅地 "编写的，所以失败应该发生在 "预期 "类型上，而不是 "实际 "类型上（`expect<Actual>().toEqualTypeOf<Expected>()`）。这意味着类型错误可能有点令人困惑，因此该库生成了一个 `MismatchInfo` 类型，试图明确说明期望是什么。例如
+=======
+When types don't match, `.toEqualTypeOf` and `.toExtend` use a special helper type to produce error messages that are as actionable as possible. But there's a bit of an nuance to understanding them. Since the assertions are written "fluently", the failure should be on the "expected" type, not the "actual" type (`expect<Actual>().toEqualTypeOf<Expected>()`). This means that type errors can be a little confusing - so this library produces a `MismatchInfo` type to try to make explicit what the expectation is. For example:

+<<<<<<< HEAD
 这是因为 TypeScript 编译器需要推断 `.toEqualTypeOf({a: ''})` 样式的类型参数，并且该库只能通过将其与通用的 `Mismatch` 类型进行比较来标记它为失败。因此，在可能的情况下，使用类型参数而不是具体类型来使用 `.toEqualTypeOf` 和 `toMatchTypeOf`。如果使用两个具体类型进行比较更加方便，可以使用 `typeof`：
+=======
+This is because the TypeScript compiler needs to infer the typearg for the `.toEqualTypeOf({a: ''})` style, and this library can only mark it as a failure by comparing it against a generic `Mismatch` type. So, where possible, use a typearg rather than a concrete type for `.toEqualTypeOf` and `.toExtend`. If it's much more convenient to compare two concrete types, you can use `typeof`:
