This project is running Android instrumtation tests in a BDD format with the help of android espresso and Cucumber BDD. Cucumber is BDD framework which works for BDD. For Android, we are going to use cucumber-jvm, java port of cucumber.

BDD's behavior text is written in a business-readable domain-specific language. It aims to communicate better between non-tech to tech over Software trueness and quality.
The readable behavior also serves as documentation.
