2013 GTAC谷歌介绍了Android平台自动化测试框架“Espresso”([url=http://www.youtube.com/watch?v=T7ugmCuNxDU]Video[/url], [url=http://goo.gl/ieunS]Slides[/url])，10月18号谷歌正式开放“Espresso”。在[url=http://googletesting.blogspot.jp/2013/10/espresso-for-android-is-here.html]谷歌测试团队博客[/url]中如下介绍“Espresso”：
[quote]The compelling thing about developing Espresso was making it easy and fun for developers to write reliable UI tests. Espresso has a small, predictable, and easy to learn API, which is still open for customization. But most importantly - Espresso removes the need to think about the complexity of multi-threaded testing. With Espresso, you can think procedurally and write concise, beautiful, and reliable Android UI tests quickly.[/quote]
Google目前已经在超过30多个应用(Drive、Maps、G+)中使用Espresso。

public void testSayHello() {
  onView(withId(R.id.name_field))
    .perform(typeText("Steve"));
  onView(withId(R.id.greet_button))
    .perform(click());
  onView(withText("Hello Steve!"))
    .check(matches(isDisplayed()));
}
