无法运行Minitest -在MiniTest::Unit::TestCase中获取未定义的类变量

Question

我正在尝试让我的模型测试并运行，并且在我的终端中得到错误

rake aborted!
uninitialized class variable @@current in MiniTest::Unit::TestCase

以下是我的珍品：

gem 'faker'

group :development, :test do
gem 'byebug'
gem 'minitest-spec-rails'
gem 'minitest-rails'
gem 'minitest-rails-capybara'
gem 'minitest-colorize'
gem 'minitest-focus'
gem 'fabrication'
gem 'capybara'
gem 'rspec-rails', '~> 2.0'
end

下面是我的user_test.rb文件：

require "test_helper"

class UserTest < ActiveSupport::TestCase

it "should create a user" do
@user = User.create!(:email => "user@gmail.com", :password => "xxxxxxxx",        :password_confirmation => "xxxxxxxx")
end

describe "should have a unique username" do
@user1 = Fabricate(:user, username: "bficho")
@user2 = Fabricate.build(:user, username: "bficho")
@user2.valid?.must_equal false
end

end

这快把我逼疯了，因为在我完成测试之前，我不能做很多事情！还有人看到这个吗？？

像这样改变你的测试：(根据this)

require "test_helper"
require 'minitest/autorun'

describe MiniTest::Spec
 it "should create a user" do
  @user = User.create!(:email => "user@gmail.com", :password => "xxxxxxxx",        :password_confirmation => "xxxxxxxx")
 end

 it "should have a unique username" do
  @user1 = Fabricate(:user, username: "bficho")
  @user2 = Fabricate.build(:user, username: "bficho")
  @user2.valid?.must_equal false
 end
end

我认为在您的情况下，将第二个测试用例从describe更改为it可能会起作用

describe "should have a unique username" do

应更改为

it "should have a unique username" do
