Test cases are always helpful to report issues. Here are two executable test cases.

One is Minitest, another one is RSpec. Since Rails uses Minitest by default, Oracle enhanced adapter uses RSpec. You can use whichever you prefer as long as it represents your issue correctly.

$ git clone https://github.com/rsim/oracle-enhanced
$ cd oracle-enhanced/guides/bug_report_templates/

• Execute the active_record_gem.rb to see if it works

$ ruby active_record_gem.rb

• Update the active_record_gem.rb to include your test case

• Execute the active_record_gem_spec.rb to see if it works

$ cd oracle-enhanced-your-testcase
$ rspec active_record_gem_spec.rb

• Update the active_record_gem_spec.rb to include your test case

This project is based on Rails bug_report_templated
