Espresso 2.0 is here!
“A release is never too late, nor is it too early. It arrives precisely when it’s meant to.” That being said, we would like to apologize for such a long wait. Part of the delay was caused by work that ensures that this does not happen again.
Espresso 2.0 is packed with new features, but perhaps the most important change is that Espresso is now part of the Android Support Library and available in the Android Open Source Project (AOSP) soon. This will make it easier for you to contribute to future releases.
With this release, we would also like to introduce the new AndroidJUnitRunner, which contains all the functionality of GoogleInstrumentationTestRunner and adds extra features, including Junit4 support.
Although this is an API-breaking release (hence the major version bump), we do not expect the majority of projects to be affected by anything other than the package name change.
We have added a new set of individual sample projects, available on GitHub, to make it easier for you to learn about the new features and get started with Espresso.
Documentation[4,5] and Javadocs[6,7,8] are still hosted on android-test-kit, but will move to d.android.com
in early 2015.
We hope that you enjoy the new Espresso experience and look forward to your feedback and contributions.
Happy holidays and happy testing!#androiddev #androidTesting
