packages/browser/src/client/tester/mocker.ts:1

• [nitpick] The import for ModuleMocker has been changed from '@vitest/mocker/browser' to 'vitest/internal/browser'. Verify that this change is intentional and that it aligns with the intended public API exposure.

import { ModuleMocker } from 'vitest/internal/browser'

packages/browser/src/client/client.ts:3

• [nitpick] Ensure that using 'vitest/internal/browser' for ModuleMocker is consistent with the rest of the codebase and does not inadvertently expose internal APIs.

import type { ModuleMocker } from 'vitest/internal/browser'

The duration calculation subtracts now() from options.startTime, which is likely reversed. Consider calculating elapsed time as now() - options.startTime.

Suggested change

	state.durations.prepare = options.startTime - now()
	state.durations.prepare = now() - options.startTime
