# Context

Vitest exposes a context module via `@vitest/browser/context` entry point. As of 2.0, it exposes a small set of utilities that might be useful to you in tests.

```ts
export const server: {
  /**
   * Platform the Vitest server is running on.
   * The same as calling `process.platform` on the server.
   */
  platform: Platform
  /**
   * Runtime version of the Vitest server.
   * The same as calling `process.version` on the server.
   */
  version: string
  /**
   * Name of the browser provider.
   */
  provider: string
  /**
   * Name of the current browser.
   */
  browser: string
  /**
   * Available commands for the browser.
   */
  commands: BrowserCommands
}

/**
 * Handler for user interactions. The support is implemented by the browser provider (`playwright` or `webdriverio`).
 * If used with `preview` provider, fallbacks to simulated events via `@testing-library/user-event`.
 * @experimental
 */
export const userEvent: {
  setup: () => UserEvent
  click: (element: Element, options?: UserEventClickOptions) => Promise<void>
  dblClick: (element: Element, options?: UserEventDoubleClickOptions) => Promise<void>
  tripleClick: (element: Element, options?: UserEventTripleClickOptions) => Promise<void>
  selectOptions: (
    element: Element,
    values: HTMLElement | HTMLElement[] | string | string[],
    options?: UserEventSelectOptions,
  ) => Promise<void>
  keyboard: (text: string) => Promise<void>
  type: (element: Element, text: string, options?: UserEventTypeOptions) => Promise<void>

  dragAndDrop: (source: Element, target: Element, options?: UserEventDragAndDropOptions) => Promise<void>
}

/**

 * A shortcut to `server.commands`.

export const commands: BrowserCommands
