Hi @aTei , thank you for this contribution.

I think that if I merge this PR the gem won't work for select2 v4.0.5? Any ideas?

The only option I see is to make it the same way as was done separation between 2, 3 & 4

Let me think a bit

Yea, could you go with this solution for now and add one test case for version v4.0.10 in a separate test file (select2_v4-0-10_spec.rb for example). And change version in spec/fixtures/select2-v4/index.html back to v4.0.5

Note that you will need separate fixture html for version v4.0.10. Name it spec/fixtures/select2-v4-0-10/index.html

Maybe omit [role='treeitem'] in the selector and add a check for [role='alert'] to filter the messages issued by select2? This way both versions could be supported.

Any chance this can make it as a released version?

@MatthewKennedy, this PR cannot be merged now because it breaks support for previous versions of select2 (v4.0.5 for example)

Hi @aTei , thank you for this contribution. I decided to test select2 version 4.0.12 thoroughly and extracted all tests to the shared folder. I run all shared tests for all tested select2 versions. See refactor tests commit and add support for 4.0.9+ commit
