所以我在“实用黄瓜”的第一个项目,我得到了我的步骤定义中未定义的方法错误。错误来自$ ?. success ?.不用说我很困惑。我错过了一个宝石或什么?
这里的步骤定义
Given /^the input "(.*?)"$/ do |input|
@input = input
end
When /^the calculator is run$/ do
@output = 'ruby calc.rb #{@input}'
raise('Command failed!') unless $?.success? #$?.success? is failing. look that up.
end
Then /^the output should be "(.*?)"$/ do |arg1|
pending # express the regexp above with the code you wish you had
end
这里的错误。
Feature: Adding
Scenario: Add two numbers # features/adding.feature:3
Given the input "2+2" # features/step_definitions/calculator_steps.rb:1
When the calculator is run # features/step_definitions/calculator_steps.rb:5
undefined method `success?' for nil:NilClass (NoMethodError)
./features/step_definitions/calculator_steps.rb:7:in `/^the calculator is run$/'
features/adding.feature:5:in `When the calculator is run'
Then the output should be "4" # features/step_definitions/calculator_steps.rb:10
Failing Scenarios:
cucumber features/adding.feature:3 # Scenario: Add two numbers
1 scenario (1 failed)
3 steps (1 failed, 1 skipped, 1 passed)

那么,这里有什么问题?我知道.success?是正确的,为什么不是$?注册?谢谢!
这工作完美(我知道这是愚蠢的)。我一定会去看看阿鲁巴。非常感谢。 – CRBairdUSA 2012-08-13 20:33:32
