Wellrailed - Cucumber tips

Cucumber and Tips(briefly)

Scenarios
Written in YAML
Scenario: Eat Cake
given there is cake
when I go to the cake page
and I press “Eat Cake”
then I should see “There is no more cake”
Get clients or stakeholders in on the writing process.

Steps
When /^I go to (.+)$/ do |page_name| visit path_to(page_name) end Generic is better.

Dealing with slow test suites Just target one feature: Cucumber features/feature.rb Specify by line number: Cucumber features/feature.rb:2:29

Avoid Excessive Givens
Each given loads data and is held in a transaction for the scenario.
Seed data where possible rather than establishing it in givens

Tagging features
Tag features and scenarios with :
@tag @tag2
Feature: cake
Run specific tags with:
cucumber --tags @tag
The @wip tag is special for WIP.

Validate your HTML
Throw in a step to validate your HTML
markup_validity gem
Then %r/the page is valid XHTML/ do
$browser.html.should be_xhtml_strict if ENV["VALIDATION"]
end
Equal opportunity for front end people to get laughed at for breaking the build.
