Rails minitest设计错误

Question

我目前正在进行我的第一次测试,但是我遇到了一个我似乎无法解决的问题.我现在已经搜索了几个小时的解决方案并发现了类似的错误,但我没有找到任何解决方案.也许是因为版本差异,我不知道.

当我用minitest编写单元测试时,问题就出现了,也许还有集成测试.我正在使用设计来管理用户.

这是我在终端时出现的错误rake test:

1) Error:
test_deactivate_enrolment(EnrolmentTest):

这就是我的spec_helper.rb样子:

require 'listen'

Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each { |f| require f }

# See http://rubydoc.info/gems/rspec-core/RSpec/Core/Configuration
RSpec.configure do |config|
  config.color_enabled = true
  config.order = :random
  config.filter_run :focus => true
  config.treat_symbols_as_metadata_keys_with_true_values = true
  config.run_all_when_everything_filtered = true
  config.filter_run_excluding :broken => true
  config.fail_fast = true
end

def test_latency
  0.1
end

# Crash loud in tests!
Thread.abort_on_exception = true

这是我的 test_helper.rb

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

# 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"
require 'minitest/autorun'

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.(yml|csv) for all tests in alphabetical order.
  fixtures :all
  include Devise::TestHelpers

  # Add more helper methods to be used by all tests here...
end

我已经尝试添加include Devise::TestHelpers失败的文件,但没有修复它.删除'test_helper.rb`中的行具有相同的结果.也许有人也有这个错误？

更新

这是测试文件,没有太高级...

要求'test_helper'

class EnrolmentTest < ActiveSupport::TestCase
  test "deactivate enrolment" do
     assert true
  end
end

Answer 1

仅在控制器测试中包含Devise助手.您的test_helper.rb文件应如下所示:

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

# 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"
require 'minitest/autorun'

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.(yml|csv) for all tests in alphabetical order.
  fixtures :all

  # Add more helper methods to be used by all tests here...
end

class ActionController::TestCase
  include Devise::TestHelpers
end
