Which is better Espresso or Appium?
Espresso provides automatic synchronization of UI elements and test actions. It automatically detects when the main thread is idle and accordingly runs test commands at the appropriate time. As a result, Espresso is faster and more stable. Unlike Appium, it does not involve any server communication.
Does Appium use Espresso?
Appium currently has support for the Espresso automation technology via its own Espresso driver. Appium also supports Android automation using the UiAutomator2 Driver.)
Is Appium black box testing?
Appium tests the actual Android application. With Espresso, you can write user interface tests (black box) but it has the same access to the internals of the application that any other unit/integration tests (white box) have, hence why it’s called “grey-box” (black box + white box).
Why is Espresso tested?
Espresso is a testing framework for Android to make it easy to write reliable user interface tests. Espresso automatically synchronizes your test actions with the user interface of your application. The framework also ensures that your activity is started before the tests run.

How is espresso used to test an app?
“The Espresso testing framework provides a set of APIs to build UI tests to test user flows within an app. These APIs let you write automated UI tests that are concise and that run reliably. Espresso is well-suited for writing white box-style automated tests, where the test code utilizes implementation code details from the app under test.”
