conducted synchronously in the main thread
uses undocumented Apple APIs
- (void)testSuccessfulLogin!

[tester enterText:@"thisismypassword"

FRANK
from outer ruby space ‘cucumber’
'Selenium for native iOS apps'.
uses undocumented Apple APIs
totally different approach to testing in iOS
Feature: Various scenarios that exercise different parts of Frank!
!
Background:!
Given I launch the app !
!
Scenario: Counting number of rows in a table section!
Then I should see 3 rows in section 0!
!
Scenario: Scrolling to the bottom of the table !
When I touch "Larry Stooge"!
And I touch "User Roles"!
Then I should not see "Returns"!
When I scroll to the bottom of the table!
Then I should see "Returns"
