处理黄瓜歧义步骤

Question

我是第一次接触黄瓜，我想就如何组织以下步骤定义征求意见。

Feature: Manage events
  In order to Manage events
  Organizer
  wants to create new events

  Background:
    Given I am logged in as organizer

  Scenario: Publish new event
    Given I am on the new event page
    When I fill in "Title" with "Rails event"
    And I fill in "Start at" with "2012-5-4"
    And I fill in "End at" with "2012-5-5"
    And I fill in "Description" with "Bla bla"
    And I check "Published"
    And I press "Create Event"
    Then I should see "Rails event"

以下是创建歧义的步骤定义，

    When /^I fill in "Start at" with "(.*?)-(.*?)-(.*?)"$/ do |year, month, day|
      enter_date(:event_start_at, year, month, day)
    end

    When /^I fill in "End at" with "(.*?)-(.*?)-(.*?)"$/ do |year, month, day|
      enter_date(:event_end_at, year, month, day)
    end

    When /^I fill in "(.*?)" with "(.*?)"$/ do |name, value|
      fill_in name, :with => value
    end

    private
    def enter_date(id, year, month, day)
        select year, :with => "#{id}_1i"
        select month, :with => "#{id}_2i"
        select day, :with => "#{id}_3i"
    end

发生的情况是，前2个定义与最后一个定义是不明确的。但是对于开始日期和结束日期，我必须以不同的方式处理它们。我所知道的是cucumber有--guess选项可以解决这个问题。但这是最佳实践吗？

Answer 1

为什么不这样做呢：

When /^I fill in "([^"]*)" with "([^"]*)"$/ do |name, value|
  case(name)
  when "Start at" then
    parts = value.split(/-/)
    enter_date(:event_start_at, parts[0], parts[1], parts[2])
  when "End at" then
    parts = value.split(/-/)
    enter_date(:event_end_at, parts[0], parts[1], parts[2])
  else
    file_in name, :with => value
  end
end

(或者，在文本框中键入这些行的内容，因此不确定是否会按原样正确运行。)

去掉"Start at“和"End at”周围的引号。它们将不再与您的最后一步匹配。我发现引号会造成很多歧义，所以我通常只使用引号来表示文件名或路径中包含空格的内容。当有疑问时，我发现删除引号是最佳实践，因为它消除了对Cucumber的大量猜测。
