-### License stubbing with `let_it_be`
-
-`let_it_be_with_refind` is also useful when using `stub_licensed_features` in your tests:
-
-```ruby
-let_it_be_with_refind(:project) { create(:project) }
-# Project#licensed_feature_available? is memoized, and so we need to refind
-# the project for license updates to be applied.
-# An alternative is `project.clear_memoization(:licensed_feature_available)`.

-subject { project.allows_multiple_assignees? }

-  before do
-    stub_licensed_features(multiple_issue_assignees: true)
-  end
-

-end
-
-context 'with license multiple_issue_assignees disabled' do
