錯誤的MINITEST寶石：NoMethodError：NoMethodError：未定義的方法`ENV」的零：NilClass *

Question

我試圖與MINITEST寶石來測試我的申請，我有一個錯誤：

錯誤[「test_User_should_be_valid 」 UserTest，2016年6月23日十六時11分17秒+0200] test_User_should_be_valid＃UserTest（1466691077.75s） NoMethodError：NoMethodError：未定義的方法`ENV」的零：NilClass

解釋什麼，我是這樣的： 所以我創建一個設計用戶命令： $ rails generate devise User 後來我把一些驗證我的模型用戶：

class User < ActiveRecord::Base 
    before_save { self.email = email.downcase } 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable, :confirmable, :lockable 

    VALID_NAME_REGEX = /\A[a-zA-Z]+\z/ 
    validates :name, presence: true, 
        length: { in: 2..50 }, 
        format: { with: VALID_NAME_REGEX, message: "is allowed only letters" } 
    VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i 
    validates :email, length: { maximum: 255 }, 
        format: { with: VALID_EMAIL_REGEX }, 
        uniqueness: { case_sensitive: false } 

end 

後，我創建的燈具users.yml裏：

default: 
    email: 'default@example.com' 
    name: "fulano" 
    encrypted_password: <%= encrypted_password %> 

，並添加fixture_file_helper_test.rb：

module FixtureFileHelpers 
    def encrypted_password(password = 'password123') 
    User.new.send(:password_digest, password) 
    end 
end 

ActiveRecord::FixtureSet.context_class.send :include, FixtureFileHelpers 

然後我在我的user_test.rb中執行此操作：

require 'test_helper' 

    class UserTest < ActiveSupport::TestCase 
    include Devise::TestHelpers 
     def setup 
     @user = User.new(:default) 
     end 

     test "User should be valid" do 
     assert @user.valid? 
     end 
    end 

然後當我嘗試用後衛來測試我有這樣一個錯誤：這是因爲它的音符生成用戶控制器（UserController.rb）

ERROR["test_User_should_be_valid", UserTest, 2016-06-23 16:11:17 +0200] 
test_User_should_be_valid#UserTest (1466691077.75s) 
NoMethodError:   NoMethodError: undefined method `env' for nil:NilClass 

我覺得發生。有必要使用Devise創建這個控制器？ 我創建UsersControllerTest：

require "test_helper" 

class UsersControllerTest < ActionController::TestCase 
    include Devise::TestHelpers 
    def setup 
    @user = users :default 
    sign_in @user 
    end 

    def teardown 
    sign_out @user 
    end 
end 

並且錯誤仍然存​​在。

我的衛隊文件使用Spring：

guard :minitest, spring: true, all_on_start: false do 
    watch(%r{^test/(.*)/?(.*)_test\.rb$}) 
    watch('test/test_helper.rb') { 'test' } 
    watch('config/routes.rb') { integration_tests } 
    watch(%r{^app/models/(.*?)\.rb$}) do |matches| 
    "test/models/#{matches[1]}_test.rb" 
    end 
    watch(%r{^app/controllers/(.*?)_controller\.rb$}) do |matches| 
    resource_tests(matches[1]) 
    end 
    watch(%r{^app/views/([^/]*?)/.*\.html\.slim$}) do |matches| 
    ["test/controllers/#{matches[1]}_controller_test.rb"] + 
    integration_tests(matches[1]) 
    end 
    watch(%r{^app/helpers/(.*?)_helper\.rb$}) do |matches| 
    integration_tests(matches[1]) 
    end 
    watch('app/views/layouts/application.html.slim') do 
    'test/integration/site_layout_test.rb' 
    end 
    # watch('app/helpers/sessions_helper.rb') do 
    # integration_tests << 'test/helpers/sessions_helper_test.rb' 
    # end 
    # watch('app/controllers/sessions_controller.rb') do 
    # ['test/controllers/sessions_controller_test.rb', 
    # 'test/integration/users_login_test.rb'] 
    # end 
    # watch('app/controllers/account_activations_controller.rb') do 
    # 'test/integration/users_signup_test.rb' 
    # end 
    # watch(%r{app/views/users/*}) do 
    # resource_tests('users') + 
    # ['test/integration/microposts_interface_test.rb'] 
    # end 
end 

# Returns the integration tests corresponding to the given resource. 
def integration_tests(resource = :all) 
    if resource == :all 
    Dir["test/integration/*"] 
    else 
    Dir["test/integration/#{resource}_*.rb"] 
    end 
end 

# Returns the controller tests corresponding to the given resource. 
def controller_test(resource) 
    "test/controllers/#{resource}_controller_test.rb" 
end 

# Returns all tests for the given resource. 
def resource_tests(resource) 
    integration_tests(resource) << controller_test(resource) 
end

Answer 1

我有一個類似的問題。我認爲你需要包括Devise::Test::ControllerHelpers並確認你創建的用戶。

見下

#test_helper.rb 
class ActionController::TestCase 
    include Devise::Test::ControllerHelpers 
end 



#users_controller_Test.rb 
require "test_helper" 

class UsersControllerTest < ActionController::TestCase 
    def setup 
    @user = users :default 
    @user.confirm 
    sign_in @user 
    end 

    def teardown 
    sign_out @user 
    end 
end
