10. What do we need?
'cucumber' => "~> 0.9.2"
'net-ssh' => "~> 2.0.23"
'webrat' => "~> 0.7.1"
'rspec' => "~> 2.0.0"
'cucumber-nagios' => "~> 0.7.6"

11. Learn Gherkin!
GIVEN
WHEN
THEN

12. Given...
Prerequisites
Not required in a scenario
“Given the user ‘tom’ exists”

13. When...
Action to take
“When I look at the directory ‘/home/tom’”

14. Then...
Results to expect
“Then it should be owned by ‘tom’”

15. And...
Just like the one above
“Then it should be owned by ‘tom’”
“And it should be mode 0755”

16. Scenario
Given the user ‘tom’ exists
When I look at the directory ‘/home/tom’
Then it should be owned by ‘tom’
And it should be mode 0755

17. That’s not Ruby!
Scenarios are in English
Step Definitions are in Ruby

18. Step Definitions
When /^I look at the directory '([^']*)'$/ do |arg1|
@filename = arg1
end
Then /^it should be owned by "([^"]*)"$/ do |arg1|
...
end
