rails 4 rspec控制器都失败了

Question

从导轨3.2.17升级到4.0.1

我的所有rspec（传入3.2.17）现在都失败了undefined method，例如

Failure/Error: delete :destroy, id: @group
NoMethodError: undefined method `delete' for
#<RSpec::ExampleGroups::GroupsController::ViewAccess::DELETEDestroy:0x000000041bc188>

Failure/Error: put :update, id: @group,
undefined method `put' for 
#<RSpec::ExampleGroups::GroupsController::ViewAccess::PUTUpdate::InvalidAttributes

Failure/Error: post :create, group: FactoryGirl.attributes_for(:group)
undefined method `post' for ...

Failure/Error: get :show, id: @group
NoMethodError: undefined method `get' for
#<RSpec::ExampleGroups::GroupsController::ViewAccess::GETShow:0x00000004c5f298>

和很多

Failure/Error: session[:user_id] = user.id
NameError:
   undefined local variable or method `session' for
#<RSpec::ExampleGroups::GroupsController::AdminAccess::DELETEDestroy:0x00000004c1ac10>

如何解决？

规范是：

      @group = FactoryGirl.create(:group, group_name: 'Tools', group_description: 'Tools and Utilities')

Answer 1

Rspec 2猜测给定的类是基于spec文件位置的控制器还是模型。默认情况下，在rspec 3中禁用此猜测，您需要将以下行添加到spec_helper（或更确切地说是rails_helper）以启用它：

config.infer_spec_type_from_file_location!

或者你需要告诉rspec你在测试什么：

describe GroupsController, type: :controller do
