JBuilder Template Test failing on CI

[stefannibrasil]

The CI is returning the following error for Ruby >= 2.7:

Failure:
JbuilderTemplateTest#test_array_of_partials [/home/runner/work/jbuilder/jbuilder/test/jbuilder_template_test.rb:103]:
Expected: "Post #5"
  Actual: nil

rails test home/runner/work/jbuilder/jbuilder/test/jbuilder_template_test.rb:100

The CI is failing even when no code changes were made. I don't have a lot of context about JBuilder and can't provide more details. I hope opening an Issue is okay. Thanks!

Thanks @stefannibrasil for reporting this issue. The issue relates to upstream rails, a change on that end caused jbuilder to break.

I did a git bisect and it looks related to the changes in rails/rails#45614

hi @hahmed thank you for doing that! I'm not sure what would be the next step. Perhaps creating an issue on Rails? Thank you!

So it looks like the rails commit is something we want to keep, which means jbuilder tests will need fixing.

I tested jbuilder in an app and it looks to be working fine, it's only the tests. Specifically the way it's setup to use ActionView.

So rails/rails#46298 makes the jbuilder test suite pass on rails_head.

I'm waiting to see if it doesn't break anything on the Rails side though. The Action View test suite passes, but that doesn't mean a lot.

thank you, @casperisfine 🎉
