On top of standard Appium requirements Espresso driver also expects the following prerequisites: There is limited support to automate out of app areas using the mobile command uiautomator Requirements It can find elements that aren't rendered on the screen, it can identify elements by the Android View Tag and it makes use of IdlingResource which blocks the framework from running commands until the UI thread is free. This distinction has a few notable benefits. The Espresso Driver itself is black-box (no internals of the code are exposed to the tester), but the Espresso framework itself has access to the internals of Android applications.

The key difference between UiAutomator2 Driver and Espresso Driver is that UiAutomator2 is a black-box testing framework, and Espresso is a "grey-box" testing framework. The server part (written in Kotlin with some parts of Java), which is running on the device under test and transforms REST API calls into low-level Espresso commands.Also includes several handlers that directly use ADB and/or other system tools without a need to talk to the server. The driver part (written in Node.js) ensures the communication between the Espresso server and Appium.

The Espresso package consists of two main parts: The driver operates in scope of W3C WebDriver protocol with several custom extensions to cover operating-system specific scenarios. The Espresso Driver is a part of the Appium framework. Appium's Espresso Driver is a test automation server for Android that uses Espresso as the underlying test technology.
