RSpec测试通过隔离，但一起运行时失败

Question

在我的code_controller_spec.rb我的测试通过，当我只在code_controller_spec.rb运行测试。但是，当我运行该套件时，只有,edit和update测试在code_controller_spec.rb内失败。我真的不确定该从哪里出发，我真的不知道为什么我的测试在一起跑步时失败。我有config.use_transactional_fixtures = false，正在使用database_cleaner。我的应用程序在下面的操作中可以正常工作，并且在创建或更新帖子时我没有收到任何错误。让我知道你是否需要额外的信息。

当我运行的套件，我得到的失败是：

1) CodesController admin pages #create posts a new code post 
    Failure/Error: 
     post :create, params: { 
     code: {

      user_id: user.id 
     } 
     }

我spec/controllers/user/codes_controller_spec.rb

RSpec.describe User::CodesController, type: :controller do 

    let!(:user) { User.create(email: "user@example.com", password: "password") } 
    let!(:code) { FactoryGirl.create(:code) } 

    before do 
    sign_in_as user 
    expect(response).to have_http_status(:success) 
    end 

    describe "admin pages" do 
    render_views 

    context "#create" do 
     it "posts a new code post" do 
     post :create, params: { 
      code: { 
      created_at: Date.today, 
      title: "Code things", 
      content: "The content of the code post", 
      user_id: user.id 
      } 
     } 
     expect(response).to redirect_to user_codes_path 
     expect(flash[:success]).to eq "Post created successfully." 
     end 
    end 

    context "#edit" do 
     it "edits a code post" do 
     get :edit, params: { id: code } 
     expect(response).to render_template :edit

    end 

    context "#update" do 
     let(:code2) do

     end 
     it "updates a code post" do 
     put :update, params: { id: code, code: code2 } 
     code.reload 
     expect(response).to redirect_to user_code_path(code) 
     expect(code.title).to eq code2[:title] 
     expect(code.content).to eq code2[:content] 
     expect(flash[:success]).to eq "Post updated successfully." 
     end 
    end 
    end 
end 

我spec/factories/post_factories.rb

FactoryGirl.define do 
    factory :code do 
    created_at Date.today 
    title "Code post title" 
    content "Coding speak that not everyone can understand..." 

    association :user, factory: :user 
    end 

    factory :life do 
    created_at Date.today 
    title "Life post title" 
    content "The world moves in mysterious ways; whether we want it to..." 

    association :user, factory: :user 
    end 
end 

我跑rspec --seed 123 --bisect，然后我跑的输出那个，但是我所有的测试都通过了。我应该提到我对--bisect非常陌生。

这是rspec --seed 123 --bisect输出，当我运行这个时，所有的测试都通过了。

我database_cleaner配置在rails_helper.rb

require database_cleaner 

RSpec.configure do |config| 
    config.use_transactional_fixtures = false 

    # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures 
    # config.fixture_path = "#{::Rails.root}/spec/fixtures" 

    config.before(:all) do 
    FactoryGirl.reload 
    end 

    # If you're not using ActiveRecord, or you'd prefer not to run each of your 
    # examples within a transaction, remove the following line or assign false 
    # instead of true. 

    config.before(:suite) do 
    if config.use_transactional_fixtures? 
     raise(<<-MSG) 
     Delete line `config.use_transactional_fixtures = true` from rails_helper.rb (or set it to false) to prevent uncommitted transactions being used in JavaScript-dependent specs.

     MSG 
    end 
    DatabaseCleaner.clean_with(:truncation) 
    end 

    config.before(:each) do 
    DatabaseCleaner.strategy = :transaction 
    end 

    config.before(:each, type: :feature) do 
    # :rack_test driver's Rack app under test shares database connection 
    # with the specs, so continue to use transaction strategy for speed. 
    driver_shares_db_connection_with_specs = Capybara.current_driver == :rack_test 

    if !driver_shares_db_connection_with_specs 
     # Driver is probably for an external browser with an app under test that does *not* 
     # share a database connection with the specs, so use truncation strategy. 
     DatabaseCleaner.strategy = :truncation 
    end 
    end

Answer 1

我相信这是一个自动加载的问题。如果您的::CodesController在Users::CodesController之前被加载，则您的Users::CodesController规范实际上使用的是::CodesController，因此无法创建正确的路由。单独运行时，正确的类是自动加载的，一切正常。要解决这个问题，需要在规范开始时提供正确的类。

# spec/controllers/user/codes_controller_spec.rb 

require 'user/codes_controller' 
... 

和

# spec/controllers/codes_controller_spec.rb 

require 'codes_controller' 
...
