ruby-on-rails - Rails fixtures dumping all data in the db

Question

I've been in Factory land for the past few years and have decided to come back to fixtures but am running into a problem.

In my test_helper.rb I have

class ActiveSupport::TestCase
  fixtures :all
end

Then in an individual test case I might be doing something like users(:one) however the data for users(:two) and the data for other tables that I am not calling on seems to be present in the test database.

So, is this the expected behavior? I have a hard to believing it is, seems strange from an isolated testing perspective.

Answer 1

fixtures :all发生这种情况是因为您从语句中一次加载所有固定装置。测试中的经验法则是仅加载给定测试所需的数据（不是全部）。这也可能会减慢您的测试运行时间。

如果您只想加载选定的灯具，您可以这样做

fixtures :<fixture name>

前任：

fixtures :users

还有一件事，你是否有特别的理由重返赛程。工厂是要走的路；它们允许您干净地组织您的测试数据。
