Hello,

I have an issue with dry-system enable_stubs method, it causes my test to fail with the following snippet:

An error occurred while loading ./spec/policies/user_policy_spec.rb.
Failure/Error: LeRegistreApi::Container.enable_stubs!

FrozenError:
  can't modify frozen Class: LeRegistreApi::Container

Here is my rails_helper: y752w - Ghostbin
And my container initializer: r3zak - Ghostbin.
What is weird is that on my other computer it works correctly. I tried uninstalling all my ruby versions/gems/rbenv and reinstalling but still have the issue. I don’t know what could cause that, I hope you can help ! Thanks a lot

There’s news to this, apparently this issue also appears on my coworker computer. But we have a ci and the tests correctly runs … My coworker is on macOs, I am on ubuntu installed on a mac but the ci is running on ubuntu-latest. I also have another coworker with a mac m1 and tests runs correctly. I also wrote a dockerfile to run the tests and I have the same issue, i’m building my docker image from ruby:2.7.5. Even weirder, if i run my tests suite whith rubymine, it works correctly…

Turns out i was running my tests in development env. Dry::Rails::Railtie config.prepare got runned somehow and it finalizes the container if we are not in test env
