Acceptance tests using Espresso Kotlin

Espresso is the most popular UI testing framework for Android. It was released by Google in 2013 and is the easiest to use of its kind. It provides support for complex things, such as ensuring that an activity is run before the tests are run, or waiting till the observed background tasks are completed. These things were hard to synchronize prior to Espresso, and UI testing was considered a difficult thing to do.
