Question

假设我有一些情况：

Feature: Creating Books
  In order to have books to read
  As a user
  I want to create them

  Background:
    Given I am on the book creation page

  Scenario: Creating a book
    When I create the book "Moby Dick"
    Then I should see "Book has been created."

和步骤定义：

Given /^I am on the ([\w\s]+)$/ do |page|
  case page
  when "book creation page"
    visit new_book_path
  else
    visit page
  end
end

Given /^there is a book "([\w\s]+)"$/ do |title|
  steps %Q{
    Given I am on the book creation page
  }
  fill_in 'Title', :with => 'Moby Dick'
  click_button 'Create'
end

When /^I create the book "([\w\s]+)"$/ do |title|
  steps %Q{
    Given there is a book #{title}
  }
end

运行黄瓜，我发现“鉴于有一本书”被理解为“何时”：

You can implement step definitions for undefined steps with these snippets:

When /^there is a book Moby Dick$/ do
  pending # express the regexp above with the code you wish you had
end

我注意到calling steps from steps避免了跨部分语音。我是否希望做到这一点，而不是重复“当有一本书”时，“当有书时”？

Answer 1

实际上我觉得你的代码是正确的，你绝对可以用这种方式调用步骤。但是你错过了步骤名称中的双引号，你试图称之为“有一本书Moby Dick”，但你所定义的步骤预计会匹配'有一本书“Moby Dick”'。如果进行以下调整：

steps %Q{
    Given there is a book "#{title}"
}

应该可以正常工作。此外，对于单行步骤，您可以使用step方法，在这种情况下可能更简洁：

step "Given there is a book \"#{title}\""

是否可以从黄瓜中的When步骤调用Given步骤？
