cucumber test 小心得

最近，有时间在参考UC berkeley一个免费在线Ruby学习课程
https://www.coursera.org/saas/class/index
写了点Cucumber测试有些心得

When /^I make all my stuff shiny$/
  step "I polish my first thing"
end

When /^I make all my stuff shiny$/
  steps %Q{
    When I polish my first thing
    When I shine my second thing
  }
end

如果有如下的类似错误，是因为使用了steps

另外一个例子

Feature: Test case

  As a cucumber user
  I want to crash MRI 1.9.3
  So I can provide a small failing test case

  Scenario: successfully crash MRI
    Given a nested task
    When I call another nested task
    Then everything fails
#==========================
require 'capybara'
require 'capybara/dsl'
require 'capybara-webkit'

Capybara.default_driver = :selenium
Capybara.app_host = 'http://www.google.com'

include Capybara::DSL

Given /^a nested task$/ do
  steps %Q{
    Given I call "first" nested task
    And "second" nested task
  }
end

When /^I call another nested task$/ do
  steps %Q{
    When I call subtask "1"
    And I call subtask "2"
    And "third" nested task
  }
end

Then /^everything fails$/ do
end

Given /^I call "([^"]*)" nested task$/ do |arg1|
  Kernel.puts "Nested task " + arg1
  visit '/'
end

Given /^"([^"]*)" nested task$/ do |arg1|
  Kernel.puts arg1 + " nested task"
end

When /^I call subtask "([^"]*)"$/ do |arg1|
  Kernel.puts "subtask " + arg1
end

一种解决办法重现编译1.9.3 with

CC=clang ./configure

and 

$ gem pristine ffi
