如何解决 Capybara::ElementNotFound 错误

Question

我遇到了以下问题，这是我第一次使用水豚，你知道我如何解决这个问题吗，谢谢

我使用rails 3.0.0和以下gems

gem 'rails', '3.0.0'
gem 'capybara'
gem 'database_cleaner'
gem 'cucumber-rails'
gem 'cucumber'
gem 'rspec-rails'
gem 'spork'
gem 'launchy'

senario中有以下内容

When I go to the new customer page
And I fill in "Email" with "[email protected]"

我在我的customer_steps中的 .rb 我

When /^I fill in "([^"]*)" with "([^"]*)"$/ do |arg1, arg2|
  fill_in arg1, :with => arg2
end

认为

- form_for @customer do |f|
  = f.label :email, 'Email'
  = f.text_field :email
  = f.submit

当我运行我的场景时，我收到此错误消息

 Scenario: Register new customer                  # features/manage_customers.feature:7
    When I go to the new customer page             # features/step_definitions/customer_steps.rb:1
    And I fill in "Email" with "[email protected]"  # features/step_definitions/customer_steps.rb:5
      cannot fill in, no text field, text area or password field with id, name, or label 'Email' found (Capybara::ElementNotFound)
      ./features/step_definitions/customer_steps.rb:6:in `/^I fill in "([^"]*)" with "([^"]*)"$/'
      features/manage_customers.feature:9:in `And I fill in "Email" with "[email protected]"'

Answer 1

我发现我的错误了！！！

When I go to the new customer page

在这一步之前

When /^I go to (.+)$/ do |page_name|
  path_to page_name 
end

我忘记了访问......

When /^I go to (.+)$/ do |page_name|
  visit path_to(page_name) 
end

Answer 2

使用该字段的 id 代替，它应该类似于

我用“[电子邮件受保护]填写“customer_email” ”

如果@customer 是对象客户模型
