Cucumber 如何测试需要从安全短语中输入两个随机字符的表单？

我需要测试一个两阶段登录系统，该系统首先询问您的电子邮件地址和密码，然后向用户提供包含[a-zA-Z0-9]的两个选择列表。下拉列表旁边的标签采用“从安全短语中选择字符X”的形式，其中X是来自已知安全短语的随机字符索引

我不希望为了验收测试而存根代码，那么有没有可能用Cumber编写一个匹配器，在我们知道整个短语的情况下，在两个列表中分别选择所需的字符

以下是我到目前为止的场景和涉及的步骤：

Scenario: valid login email, password and secret phrase takes me to the dashboard
  Given I am not logged in
  When I log in as "admin@example.com"
  Then I should be on the dashboard page
  And I should see "Your Dashboard"

When /^I log in as "([^\"]*)"$/ do |login|
  visit path_to('Login page')
  fill_in "Email", :with => login
  fill_in "Password", :with => "Password123"
  click_button "Log in"
  response.should contain("Please verify some characters from your security phrase")
  select "a", :from => "Select character X of your security phrase"
  select "b", :from => "Select character Y of your security phrase"  
  click_button "Submit"
end

例如，如果安全短语为'Secret123'，X=3，Y=8，则上述必须产生以下等价物：

select "c", :from => "Select character 3 of your security phrase"
select "2", :from => "Select character 8 of your security phrase"

实际页面中的数字X和Y分别位于span#svc_1和span#svc_2内

谢谢，

经过一番折腾，我终于明白了。将其记录在此处，以便在相同情况下帮助其他人。通常情况下_steps.rb：

When /^I log in as "([^\"]*)"$/ do |email|
  visit path_to('Login page')
  fill_in "Email", :with => email
  fill_in "Password", :with => "password"
  click_button "Log in"
  response.should contain("Please verify some characters from your secret phrase")
  select_correct_secret_phrase_char("span#sec_1")
  select_correct_secret_phrase_char("span#sec_2")
  click_button "Submit"
end

def select_correct_secret_phrase_char(css_selector)
  response.should have_selector(css_selector) do |scope|
    select "Secret1"[(scope.text.to_i)-1].chr, :from => "Select character #{scope.text} of your security phrase"
  end
end
