Running zeitwerk unit tests raise `NameError: uninitialized constant` #2908

Closed yahonda closed 3 months ago

yahonda commented 3 months ago

zeitwerk is Rails default autoloader. I have run zeitwerk unit test with prism enabled Ruby, it raises these NameError: uninitialized constant

Steps to reproduce

git clone https://github.com/fxn/zeitwerk
cd zeitwerk
bundle install
RUBYOPT=--parser=prism bundle exec rake test

Expected result

All of tests should pass as follows.

$ ruby -v
