 For browser mode, you can use the base browser runtime (`@vitest/browser`) and Preview provider (`@vitest/browser-preview`) included in `vite-plus`. To use Playwright or WebDriverIO, you also need the opt-in provider (`@vitest/browser-playwright` or `@vitest/browser-webdriverio`) and its framework peer (`playwright` or `webdriverio`).
