Rails 7 and Zeitwerk not loading in tests

My Rails 7, Ruby 3.1 App has a simple test that is failing. I am not understanding why.

In my App I have added a support directory labelled stuff, which has some GraphQL code in it. So in my tests, I want to do a GraphQL.test(foo: "me", bar: "you").

app/stuff/graphql.rb

In my inflections.rb initializer, I teach the Inflection I want.

ActiveSupport::Inflector.inflections(:en) do |inflect|
  inflect.acronym 'GraphQL'
end

In my application.rb, I tell Zeitwerk that I have stuff to work with, and the rake task zeitwerk:check says everything is good.

The graphql.rb has a simple test function:

module GraphQL
  def self.test(foo:, bar:)
    puts "We got a #{foo} and a #{bar}"
  end
end

But my tests run, and when testing out this code, the test fails on GraphQL not having a test method.

I am confused by the autoloading and eager loading, and why my tests seem unable to follow the simple setup here.

It seems this was due to namespace issues with Zeitwerk. In my tests, I had a require that introduced the same namespace on a different object, namely GraphQL. So when in the tests, the named method was not found, as the Object returned was in the wrong namespacce. I removed the require, and the tests completed as expected, with no errors.
