Covers integration testing with selenium and cucumber.

1. Unit Tests Aren’t Enough
and your QA guy can’t regression test for you...

2. Will this test save you?
def test_create_new_widget
post :create_widget
assert_response :success
end

3. With this code?
# view:
<%= form_for :widget %>
<%= submit_tag “Create” %>
<% end %>
# controller:
def create; puts “doing nothing”; end

4. The Individual Pieces
Work...

5. ... but your application
does not!

6. What do we do?

7. QA Guy!

8. Benefits

9. Would he find the bug
from before?

10. What if the bug came
from a refactoring?

11. YOU are ultimately
responsible for your app

12. Let’s Automate

13. Hello, Selenium!

14. The Code

15. The API

16. Programmers still do
the testing!

17. Hello, Cucumber!

18. QA Can Write This
Scenario: Searching on Google
Given I am on the homepage
When I fill in “q” with “cukes”
And I press “Google Search”
Then I should see “cukes.info”

19. Scenario: Searching on Google

20. Given I am on the homepage

21. When I fill in “q” with “cukes”

22. And I press “Google Search”

23. Then I should see “cukes.info”

24. The Output
Scenario: Searching on Google # features/google_search.feature:6
Given I am on the homepage # features/step_definitions/webrat_steps.rb:6
When I fill in "q" with "cukes" # features/step_definitions/webrat_steps.rb:29
And I press "Google Search" # features/step_definitions/webrat_steps.rb:17
Then I should see "cukes.info" # features/step_definitions/webrat_steps.rb:121
1 scenario (1 passed)

26. Webrat Caveats
• Won’t detect elements hidden by a class
• Won’t click things that aren’t links or
buttons (usually not a big deal)

27. Beyond Webrat
When /^I search for “([^”])”$/ do |s|
When %Q|I fill in “q” with “#{s}”|
And %Q|I press “Google Search”|
end

28. Cucumber Structure
features/*.feature
