Today, I encountered the following "LoadError: cannot load such file -- ruby2_keywords" error, when executing test with ruby 2.6.

% bundle exec rails test
/Users/sanak/Build/rb/redmine42/vendor/bundle/ruby/2.6.0/gems/activesupport-5.2.8.1/lib/active_support/dependencies.rb:291:in `require': cannot load such file -- ruby2_keywords (LoadError)

The same test was no problem at 2022/10/29,

• 2022/10/29: https://github.com/sanak/redmine_text_blocks/actions/runs/3350364367

and from checking the installed gem diff, the cause seems to be mocha 2.0.0 which was released at 2022/11/01.

• https://rubygems.org/gems/mocha/versions/2.0.0

From the following mocha document, the latest 2.0.0 only supports ruby >= 2.7,

• GitHub: https://github.com/freerange/mocha/blob/main/docs/Mocha/Configuration.html#L569
  • Website: https://mocha.jamesmead.org/Mocha/Configuration.html

so, when ruby < 2.7, mocha should be < 2.0.0.

I upload a patch for that, but I am not sure whether it is enough, so reviewing it is helpful.
