Question

我正在尝试使用MiniTest测试我的rails 4应用程序。我有一些种子数据，以获得应用设置。种子数据加载到测试数据库后，我尝试运行测试。

test_seed.rake

namespace :db do
  namespace :test do
    desc "Load seed data before running tests"
    task :prepare => :environment do
      puts "\nLoading Seed data.....\n\n"
      Rake::Task["db:seed"].invoke
      puts "\n....Seed data loaded!\n\n"
    end
  end
end

完成后，我做了

rake db:test:prepare

然后，当我简单地说'耙'＆＃39;命令（截至目前我没有编写任何测试用例）

test_helper.rb中

ENV["RAILS_ENV"] = "test"
require File.expand_path("../../config/environment", __FILE__)
require "rails/test_help"
require "minitest/rails"

# To add Capybara feature tests add `gem "minitest-rails-capybara"`
# to the test group in the Gemfile and uncomment the following:
require "minitest/rails/capybara"

# Uncomment for awesome colorful output
require "minitest/pride"

# Code coverage, refer https://github.com/colszowka/simplecov
require 'simplecov'
SimpleCov.start

# Create customizable MiniTest output formats
require "minitest/reporters"
Minitest::Reporters.use!(
    Minitest::Reporters::SpecReporter.new,
    ENV,
    Minitest.backtrace_filter
)

class ActiveSupport::TestCase
  ActiveRecord::Migration.check_pending!
  include FactoryGirl::Syntax::Methods
  # Setup all fixtures in test/fixtures/*.(yml|csv) for all tests in alphabetical order.
  #
  # Note: You'll currently still have to declare fixtures explicitly in integration tests
  # -- they do not yet inherit this setting
  fixtures :all

  # Add more helper methods to be used by all tests here...
  extend MiniTest::Spec::DSL
end

class ActionDispatch::IntegrationTest
  extend MiniTest::Spec::DSL
  include Capybara::DSL
end

的Gemfile：

group :test do
  # MiniTest
  gem 'minitest-spec-rails', '5.2.0'
  gem 'minitest-rails-capybara', '2.1.1'
  gem 'minitest-reporters', '1.0.5'
  gem 'guard-minitest', '2.3.1'
  gem 'launchy'
  gem 'factory_girl_rails', "~> 4.2.1"
  gem 'faker', '1.4.3'
  gem 'simplecov', '0.9.2', require: false
end

现有测试，role_test.rb：

require 'test_helper'

class RoleTest < ActiveSupport::TestCase


  test "nothing" do
    assert true
    # role_names = Role.where(name: 'superAdmin').collect(&:name)
    # assert_includes role_names, 'SuperAdmin', 'it should include role superAdmin'
  end

失败并出现以下错误：

RoleTest
  test_0001_nothing                                              ERROR (0.02s)

任何人都可以帮助我，为什么我得到这个错误？如果可能的话，建议修复它。
