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.

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()));
}
