resolveSnapshotPath

• Type: (testPath: string, snapExtension: string, context: { config: SerializedConfig }) => string
• Default: stores snapshot files in __snapshots__ directory

Overrides default snapshot path. For example, to store snapshots next to test files:

import { defineConfig } from 'vitest/config'

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

You can also use the context parameter to access the project's serialized config. This is useful when you have multiple projects and want to store snapshots in different locations based on the project name:

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,
      )
    },
  },
})
