Writing cucumber test cases

Question

I am trying to lear how to write test scripts for frank ( cucumber test scripts).

This is what I have written

When I navigate to "aaa"
Then I should be on the aaa screen
Then I navigate to "bob"
Then I should be on the bob screen 

When /^I navigate to "(.*?)"$/ do |aaa|
  touch "view:'UITabBarButton' marked:'aaa'"
END

Then /^I should be on the aaa screen$/ do
  check_element_exists "view:'UIImageView' marked:'xxx'"
END

Then /^navigating to "(.*?)"$/ do |bbb|
  touch "view:'UITabBarButton' marked:'bbb'"
end

Then /^I SHould be on the bbb screen$/ do
   check_element_exists "view:'UIImageView' marked:'zzz'"
end

where the letters are written instead of the view/picture names

This is what i get while running the script

/Users/janogrodowczyk/SMHI/ios/ios/Frank/features/step_definitions/test_steps.rb:14: syntax error, unexpected $end, expecting kEND (SyntaxError)

And i have no idea what i am doing wrong since the first 2 rows

When I navigate to "aaa"
Then I should be on the aaa screen

are working fine when only they are run without the rest.

Best Regards

Answer 1

END and end are different ruby keywords.

END represents code to be executed before the end of a program.

end designates the end of a class, method, control structure, etc.

Answer 2

Navigating to "aaa" and "bbb" is actually two scenarios. You can't "navigate" again in one scenario.

So, firstly refactor your steps from

When I navigate to "aaa"
Then I should be on the aaa screen
Then I navigate to "bob"
Then I should be on the bob screen

To:

Given blah blah
When I navigate to "aaa"
Then I should be on the aaa screen

Given blah blah
When I navigate to "bbb"
Then I should be on the bbb screen

But, wait. Why duplicate? `Scenario Outline" could help you to test similar cases.

Scenario Outline: Visit UI
Given blah blah
When I navigate to <link>
Then I should see <screen_name> screen

Examples:
  | link | screen_name |
  | aaa  | aaa screen  |
  | bbb  | bbb screen  |
  | ccc  | ccc screen  |
