Mobile test automation is just another era for test automation since the trends for mobile devices are increasing. For more sophisticated testing approach, we should apply the technics what we have learnt from the test automation for desktop/web applications. As test automation is a part of continuos development, it should be run after each commit to test environment. For mobile application we can use the same method to be more responsible. Cucumber is used describe the test cases and it very easy to understand for anyone so we can use it for user behaviour as behaviour driven development, BDD . Capybara is a library to simulate user behaviour for just web application. However we can use Calabash for mobile test automation. It means that we can use Calabash and Cucumber together for mobile test automations. As in Capybara, in Calabash there are not much functions to learn. It has basically, finding element, inserting text into textEdit fields, clicking and assertion function
Not a feature, but the future of an app is under testing.
