Appium-Drivers-Espresso(Android)

这是一款用于Android的谷歌官方的测试框架

Appium currently has support for the Espresso automation technology via its own Espresso driver. This driver works by kicking off an Espresso run on a device, with our own automation server as part of the Espresso test APK. Appium can then communicate with this automation server and trigger Espresso commands as the result of Appium client calls.
