Rails 测试夹具用户的电子邮件显示为空

Question

我正在尝试测试登录系统是否正常工作。我用测试用户创建了一个用户装置。

test/fixtures/users.yml

dave:
  name: Mr Dave
  email: dave@dave.com
  password_digest: <%= User.digest('password') %>

我已经为登录系统创建了一个单元测试，用于测试用户登录和注销。

test/integration/site_layout_test.rb

require 'test_helper'

def setup
    @user = users(:dave)
end

...

  test "login with valid information followed by logout" do
    get login_path
    post login_path, params: { session: { email:    @user.email,
                                          password: 'password' } }
    assert is_logged_in?
    assert_redirected_to @user
    follow_redirect!
    assert_template 'users/show'
    assert_select "a[href=?]", login_path, count: 0
    assert_select "a[href=?]", logout_path
    assert_select "a[href=?]", user_path(@user)
    delete logout_path
    assert_not is_logged_in?
    assert_redirected_to root_url
    follow_redirect!
    assert_select "a[href=?]", login_path
    assert_select "a[href=?]", logout_path,      count: 0
    assert_select "a[href=?]", user_path(@user), count: 0
  end
end

当我尝试运行测试时，我收到一条错误消息，指出 NilClass 没有电子邮件方法。

Error:
SiteLayoutTest#test_login_with_valid_information_followed_by_logout:
NoMethodError: undefined method `email' for nil:NilClass
    test/integration/site_layout_test.rb:35:in `block in <class:SiteLayoutTest>'

为什么 Rails 没有提取我添加到 fixtures 文件夹的用户？

Answer 1

我认为它应该为您指明正确的方向，如果您仍有问题，请告诉我

Answer 2

原因是 setup 在测试 class 之外，因此运行没有。将它移到 class 声明中，它将顺利运行。

class SomeTest < ActionDispatch::IntegrationTest
  def setup
    @user = users(:dave)
  end
