未定义的方法`use_transactional_tests ='用于#<RSpec :: Core ::配置:0x007fccf515e338>(NoMethodError)

Question

我正在测试新的Rails版本5.0.0.alpha和RSpec,3.1.7但我收到错误:

undefined method `use_transactional_tests=' for #<RSpec::Core::Configuration:0x007fccf515e338> (NoMethodError)

在rails_helper.rb我通常使用这一切,一切正常:

config.use_transactional_fixtures = true

但我收到了这个警告:

DEPRECATION WARNING: use_transactional_fixtures= is deprecated and will be removed from Rails 5.0 (use use_transactional_tests= instead). (called from block in <module:FixtureSupport> at /Users/monteirobrena/.rvm/gems/ruby-2.2.2@global/gems/rspec-rails-3.1.0/lib/rspec/rails/fixture_support.rb:25)

所以,我改变了我rails_helper.rb的使用方式:

config.use_transactional_tests = true

现在我收到了这个错误:

有任何想法吗？谢谢.

您获得的弃用警告和建议来自Rails,而不是RSpec或rspec-rails gem.rspec-rails gem实现use_transactional_fixtures=并转向并在Rails中调用相同的方法,按照https://github.com/rspec/rspec-rails/blob/3-3-maintenance/lib/rspec/rails/fixture_support.rb.它没有实现use_transactional_tests=,因此当您进行更改时,您将收到该错误消息.

在升级rspec-rails gem以支持新的Rails 5功能之前,您需要直接设置Rails配置.
