Presentation I gave at the October Sydney RORO meetup on Cucumber, the new Ruby library for writing executable story-based tests; and FactoryGirl, a library for creating valid AR models for tests/specs/stories. Most examples come from the Webjam codebase which can be found on github: http://github.com/webjam/webjam/ Video of the preso can be found here: http://www.viddler.com/explore/snapperwolf/videos/7 Faces preso page here: http://faces.rubyonrails.com.au/groups/sydney/meetings/2008-10-08/presos/2

21. DEMO: WEBJAM
http://github.com/webjam/webjam - rake features

23. /features

24. /features/*.feature

25. Story: Viewing the home page
As a visitor
I want to visit the home page
So that I can see all the cool stuff
Scenario: not logged in
Given I am not logged in
When I view the home page
Then I see the page
/features/home.feature

26. /features/steps

27. /features/steps/*_steps.rb

28. When quot;I view the home pagequot; do
get home_path
end
/features/home_steps.rb

29. Then quot;I see the pagequot; do
response.code.should == quot;200quot;
end
/features/response_steps.rb

30. FEATURES

31. RUBY

32. RAILS INTEGRATION

33. TREETOP

34. STORY RUNNER COMPATIBLE

35. FIT TABLES

36. Feature: Addition
In order to avoid silly mistakes
As a math idiot
I want to be told the sum of two numbers
Scenario: Add two numbers
Given I have entered 50 into the calculator
And I have entered 70 into the calculator
When I press add
Then the result should be 120 on the screen
And the result class should be Fixnum
| input_1 | input_2 | button | output | class |
| 20 | 30 | add | 50 | Fixnum |
| 2 | 5 | add | 7 | Fixnum |
| 0 | 40 | add | 40 | Fixnum |

37. Before do
@calc = Calculator.new
end
After do
end
Given quot;I have entered $n into the calculatorquot; do |n|
@calc.push n.to_i
end
When /I press (w+)/ do |op|
@result = @calc.send op
end
Then /the result should be (.*) on the screen/ do |result|
@result.should == result.to_f
end
Then /the result class should be (w*)/ do |class_name|
@result.class.name.should == class_name
end
