  1) Error:
Caching::misc#test_0001_does not cache already cached results:
Mocha::NotInitializedError: Mocha methods cannot be used outside the context of a test

Seems like the root cause is we're not initializing mocha correctly. More details at:

I think the problem is actually that you are not initializing Mocha correctly. For quite a long time now, Rails has been using Minitest not Test::Unit, and so you should be requiring "mocha/minitest"

Using mocha/minitest is also mentioned in the README:

https://github.com/freerange/mocha/tree/v1.5.0#minitest-1

MiniTest
# Gemfile in Rails app
gem 'mocha'

# At bottom of test_helper.rb (or at least after `require 'rails/test_help'`)
require 'mocha/minitest'
