# resolveSnapshotPath 

* **类型：** `(testPath: string, snapExtension: string, context: { config: SerializedConfig }) => string`
* **默认值：** 将快照文件存储在 `__snapshots__` 目录中

覆盖默认快照路径。例如，要将快照存储在测试文件旁边：

```ts
import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    resolveSnapshotPath: (testPath, snapExtension) => testPath + snapExtension,
  },
})
```

你也可以使用 `context` 参数来访问项目的序列化配置。当你有多个 [项目](/guide/projects) 并且想要根据项目名称将快照存储在不同位置时，这很有用：

```ts
import { basename, dirname, join } from 'node:path'
import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    resolveSnapshotPath(testPath, snapExtension, context) {
      return join(
        dirname(testPath),
        '__snapshots__',
        context.config.name ?? 'default',
        basename(testPath) + snapExtension,
      )
    },
  },
})
```
