我已经编写了一个集成测试来在我的Rails应用程序中创建一个新人。注册表（使用Devise）在开发和生产中都很好用，但我也希望有一个规范。
然而规格失败了，我看到了一些奇怪的行为。这个规格是唯一一个失败的规则 - 所有其他规则都通过了。
我在日志中注意到dev / prod中的日志显示
Processing by Devise::RegistrationsController#create
并且传递的参数是
Parameters: {"utf8"=>"✓", "authenticity_token"=>"sRvErzoB/SwegGe/hNRp3J4zJ7i9Rk5yVY0sHymgW7M=", "person"=>{"first_name"=>"Warbling", "last_name"=>"Goose", "email"=>"goose@test.co", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Sign up!"}
另一方面，当运行规范时，测试日志显示
Processing by Devise::RegistrationsController#new as HTML
并且传递的参数是
Parameters: {"person"=>{"first_name"=>"Warbling", "last_name"=>"Goose", "email"=>"goose@test.co", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Sign up!"}
有趣的是，我没有看到在测试日志中传递了authenticity_token吗？
这是我的Gemfile：
source 'https://rubygems.org'
group :development, :test do
gem 'factory_girl_rails', '4.5.0'
gem 'shoulda-matchers', require: false
gem 'rspec-rails', '2.99.0'
gem 'capybara', '2.4.4'
gem 'launchy'
gem 'pry'
gem 'faker'
gem 'populator'
end
group :test do
gem 'database_cleaner'
gem 'email_spec'
gem 'pry-byebug'
end
group :development do
gem 'guard-rspec', require: false
gem 'spring', '1.1.3'
gem 'rails_layout'
end
group :doc do
gem 'sdoc', '~> 0.4.0'
end
gem 'rails', '4.1.6'
gem 'slim-rails'
gem 'pg'
gem 'sass-rails', '~> 4.0.3'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '2.2.4'
gem 'bootstrap-sass'
gem 'figaro', '1.0.0'
gem 'simple_form', '~> 3.1.0.rc2'
gem 'devise', '3.4.1'
gem 'font-awesome-rails'
这是我的spec_helper.rb：
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'shoulda/matchers'
require 'faker'
require 'email_spec'
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
ActiveRecord::Migration.maintain_test_schema!
RSpec.configure do |config|
config.include Devise::TestHelpers, :type => :controller
# Include Factory Girl syntax to simplify calls to factories
config.include FactoryGirl::Syntax::Methods
config.include EmailSpec::Helpers
config.include EmailSpec::Matchers
config.fixture_path = "#{::Rails.root}/spec/fixtures"
config.use_transactional_fixtures = false
config.infer_base_class_for_anonymous_controllers = false
config.order = "random"
config.infer_spec_type_from_file_location!
config.before(:suite) do
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.strategy = :transaction
end
config.before(:each, :js => true) do
DatabaseCleaner.strategy = :truncation
end
config.before(:each) do
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
config.before(:suite) do
require "#{Rails.root}/db/seeds.rb"
end
end
规范本身：
require 'spec_helper'
require 'capybara/rspec'
feature 'Person creates an account' do
scenario 'Successfully' do
visit root_path
click_link 'Sign up'
fill_in_with_valid_data
expect { click_button 'Sign up!' }.to change(Person, :count).by(1)
email = open_email('goose@test.co')
click_first_link_in_email
expect(page).to have_content( "Your email has been confirmed.")
end
def fill_in_with_valid_data(attributes = {})
fill_in 'person_first_name', :with => 'Warbling'
fill_in 'person_last_name', :with => 'Goose'
fill_in 'person_email', :with => 'goose@test.co'
fill_in 'person_password', :with => 'password'
fill_in 'person_password_confirmation', :with => 'password'
end
end
规范的日志输出：

如果它有用，请注册表格：
= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f|
.container

.panel.panel-info

= link_to "Sign in", new_person_session_path
.panel-body style="padding-top:30px"

.input-group style=("margin-bottom: 25px")

看起来好像你在表单里面有一个表单。
= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f|
...
form#signupform.form-horizontal role="form"
...
您的规范可能使用第二个嵌入表单的默认操作。由于第二个嵌入表单上没有指定操作属性，因此默认为您在/people/sign_up上的当前页面，并且由于第二个表单上没有方法属性，因此默认为GET请求时表格已提交。
这就是为什么您看到表单作为GET请求提交到同一个注册页面。
