Rails 应用程序和 Cucumber with Factory Girl 中的验证失败错误

Question

我在尝试运行 Devise 用户登录功能时出现以下错误：“验证失败：电子邮件地址已被使用”。

我怀疑问题出在工厂生成的用户中，该用户以某种方式使用相同的电子邮件地址创建了两次。我尝试运行 rake db:test:prepare 来重置测试数据库，不幸的是，没有结果。

我的 user_factory.rb

Factory.define :user do |user|
  user.email "user_#{rand(1000).to_s}@example.com"
  user.password "password"
  user.confirmed_at nil
end

因验证错误而失败的步骤是“那么我应该注册并登录” 和 “用户登录”。我的 signing_in.feature

Feature: Signing in
  In order to use the site
  As a user
  I want to be able to sign in

  Scenario: Signing in via confirmation
    Given there is an unconfirmed user
    And I open the email with subject "Confirmation instructions"
    And they click the first link in the email
    Then I should be registered and signed in

  Scenario: Signing in via form
    Given there is a confirmed user
    And I am on the homepage
    And user signs in
    Then I should see "Signed in successfully"

我的 user_steps.rb

def unconfirmed_user
  @unconfirmed_user = Factory(:user)
end


def sign_up user
  visit '/users/sign_up'
  fill_in('Email', :with => "[email protected]")
  fill_in('Password', :with => user.password)
  fill_in('Password confirmation', :with => user.password)
  click_button('Sign up')
end

def sign_in user
  visit 'users/sign_in'
  fill_in('Email', :with => user.email)
  fill_in('Password', :with => user.password)
  click_button('Sign in')
end

When /^I'm signing up$/ do
  sign_up unconfirmed_user
end

Given /^there is an unconfirmed user$/ do
  unconfirmed_user
end

Given /^there is a confirmed user$/ do
  unconfirmed_user.confirm!
end

Then /^I should be registered and signed in$/ do
  page.should have_content("Signed in as #{unconfirmed_user.email}")
end

Given /^user signs in$/ do
  sign_in unconfirmed_user.confirm!
end

When /^I open the email with subject "([^"]*?)"$/ do |subject|
  open_email(@unconfirmed_user.email, :with_subject => subject)
end

它可能是什么？ 预先感谢您的帮助。

Answer 1

您应该在测试之间清除数据库，主要使用 database_cleaner。请检查手册，因为设置之间的配置有所不同。我们正在使用这个（在 env.rb 中）：

DatabaseCleaner.strategy = :truncation
Before do
  DatabaseCleaner.clean
end

此外，您应该删除工厂文件中的 rand 指令并使用 FactoryGirl 提供的好东西：

 u.sequence(:email){|n| "user_#{n}@example.com" }
