For example if you want to run with Chrome and change your driver to chrome but not define it, it gives some errors like following irb(main):007:0> visit "http://www.amazon.com" Capybara::DriverNotFoundError: no driver called :chrome was found, available drivers: :rack_test, :selenium, :poltergeist from /Library/Ruby/Gems/2.0.0/gems/capybara-2.4.1/lib/capybara/session.rb:77:in `driver' from /Library/Ruby/Gems/2.0.0/gems/capybara-2.4.1/lib/capybara/session.rb:226:in `visit' from /Library/Ruby/Gems/2.0.0/gems/capybara-2.4.1/lib/capybara/dsl.rb:51:in `block (2 levels) in 'if you add the following line into your env.rb module, you will successfully run under Chrome driver.

BDD is developed on the top of TDD, which is stand for test driven development to remove the gap of unit testing and acceptance testing. In TDD, every unit is started to be written right after defining the expectations from the units, by the unit testing. However by BDD, regarding the agile story, every unit is specified and tested in terms of desired behaviour. This 'desired behaviour' is what exactly business requires in agile stories. 
BDD can be applied by the help of some tools to interpret the business 'desired behaviour' to test code. There are some tools that help this aim such as Behat for PHP, JBhave for Java world, and the most famous one Cucumber for the Ruby world. In this post I want to give some points on how to effectively we can use Cucumber for a Calabash project to automate some agile stories for sample android application.


Cucumber takes some keywords like Given, When, And,…
