The current behaviour does not specify a default role for the radio component, but does for the radiogroup.

Expected behavior 🤔

A default role of 'radio' should be specified for radio.

I'm unable to use '@testing-library/react' to search for the specific radio buttons via role to confirm if they are checked in a consistent manner.

As a temporary workaround I am manually specifying the role on the radio elements, but it would be better to have this fixed at the library level.

After digging a bit further, it looks like the role can be inferred by the combination of an input with the 'radio' type
