RSpec测试隔离通过，但一起运行时失败 [英] RSpec tests pass in isolation, but fail when run together
问题描述
在我的 code_controller_spec.rb 中，只要我在 code_controller_spec.rb 中运行测试，我的测试就会通过.但是，当我运行套件时，在 code_controller_spec.rb 中只有 create ， edit 和 update 测试失败..我真的不确定从那里去哪里，我真的不知道为什么我的测试一起运行时为什么会失败.我有 config.use_transactional_fixtures = false ，并且正在使用 database_cleaner .我的应用通过以下操作在本地运行良好，创建或更新帖子时未收到任何错误.让我知道您是否需要其他信息.
In my code_controller_spec.rb my tests pass when I just run the tests in code_controller_spec.rb. However, when I run the suite, only the create, edit, and update tests fail within code_controller_spec.rb. I'm really not sure where to go from here and I really don't know why my tests fail when running together. I have config.use_transactional_fixtures = false and am using database_cleaner. My app works fine locally with the below actions and I don't receive any errors when creating or updating a post. Let me know if you need additional info.
运行套件时，出现的故障是:
When I run the suite, the failures I get are:
1) CodesController admin pages #create posts a new code post
Failure/Error:
post :create, params: {
code: {
created_at: Date.today,
title: "Code things",
content: "The content of the code post",
user_id: user.id
}
}

2) CodesController admin pages #edit edits a code post
Failure/Error: get :edit, params: { id: code }
ActionController::UrlGenerationError:

end
end
end
end
我的 spec/factories/post_factories.rb
FactoryGirl.define do
factory :code do

content "Coding speak that not everyone can understand..."
association :user, factory: :user
end
factory :life do

association :user, factory: :user

我运行 rspec --seed 123 --bisect ，然后运行该输出，但所有测试都通过了.我应该提一下，我对-bisect 还是很陌生.
I run rspec --seed 123 --bisect and then I run the output of that, but all my tests pass. I should mention I'm very new to --bisect.
这是 rspec --seed 123 --bisect 的输出，当我运行此命令时，所有测试都通过了.
This is the rspec --seed 123 --bisect output and when I run this all my tests pass.

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.
During testing, the app-under-test that the browser driver connects to uses a different database connection to the database connection used by the spec. The app's database connection would not be able to access uncommitted transaction data setup over the spec's database connection.

推荐答案
我相信这是一个自动加载问题.如果您的 :: CodesController 在 Users :: CodesController 之前加载，则您对 Users :: CodesController 的规范实际上是在使用 :::CodesController ，因此无法创建正确的路由.单独运行时，将自动加载正确的类，并且一切正常.要解决此问题，需要在规范开始时使用正确的类.
I believe this is an autoload issue. If your ::CodesController gets loaded before the Users::CodesController then your spec for Users::CodesController is actually using ::CodesController and hence can't create the correct routes. When run singly the correct class is autoloaded and everything works correctly. To fix this require the correct class at the beginning of your spec.
# spec/controllers/user/codes_controller_spec.rb
require 'user/codes_controller'
...
和
# spec/controllers/codes_controller_spec.rb
require 'codes_controller'
...
