Add steps

After features, we need to add the steps to actual execute call the methods.

We just need to create one file "steps.rb" under "step_definitions" folder.

The content of "steps.rb" should contains following:

Given /^I compose a new MMS$/ do
    mms = find_element id: 'com.android.mms:id/action_compose_new'
    mms.click
end

And /^I fill "(.*?)" with "(.*?)"$/ do |field, value|
    element = find field
    element.send_keys value
end

When /^I navigate Back$/ do
    $driver.back
end

And /^I discard the changes$/ do
    discard = button 'OK'
    discard.click
end

Then /^the message should be discarded$/ do
    content = find_element id: 'com.android.mms:id/empty'
    content.text.should == "No conversations."
    screenshot './message_disacrd.png' # the path here is on your machine
end
