Hello everyone, thanks for landing on my blog post. I have used Espresso Testing framework excessively in my career and I want to share my experience in form of short and simple tutorials so that any beginner can set up and start writing automates test scripts.

Mobile automation testing is difficult considering variety of different android devices and OS versions.But I have simplified the Espresso for you all. As per my experience Espresso is great tool supported by Google for functional testing. Espresso allows you to do inter app testing and code coverage measure.

What is Espresso ?

Espresso is Android's Testing Framework used for writing effective and reliable UI Test cases.Espresso synchronizes actions written in test with application user interface.Before Test case run Espresso ensures that the activity is started. Espresso is intended to perform testing on single application but still it allows testing outside of your application as a black box testing.

Espresso Test cases has three components View Matchers,View Actions and View Assertions. We will see there components in detail as we move on to Espresso Tutoprial.
