Just for the record, the list of packages using minitest is not exactly
short:

$ repoquery --repoid=rawhide --repoid=rawhide-source --arch=src
--whatrequires 'rubygem(minitest)' --qf="%{NAME}" | wc -l

> as you have probably noticed we would like to update Rails framework to the latest version (4.1) when it's released[1].
> The biggest task for us in this change is the update of Minitest to version 5. This would require test suites
> of many gems that depends on Minitest to be fixed.
>
> Here are the most significant changes of Minitest 5 taken from the changelog[2]:
>
> * 12 major (oft incompatible) changes:
>
>   * Renamed MiniTest to Minitest. Your pinkies will thank me. (aliased to MiniTest)
>   * Removed MiniTest::Unit entirely. No more manager objects.
>   * Added Minitest::Runnable. Everything minitest can run subclasses this.
>   * Renamed MiniTest::Unit::TestCase to Minitest::Test (subclassing Runnable).
>   * Added Minitest::Benchmark.
>     * Your benchmarks need to move to their own subclass.
>     * Benchmarks using the spec DSL have to have "Bench" somewhere in their describe.
>   * MiniTest::Unit.after_tests moved to Minitest.after_tests
>   * MiniTest::Unit.autorun is now Minitest.autorun. Just require minitest/autorun pls.
>   * Removed ParallelEach#grep since it isn't used anywhere.
>   * Renamed Runnable#__name__ to Runnable#name (but uses @NAME internally).
>   * Runnable#run needs to return self. Allows for swapping of results as needed.
>
> That means the minimal changes needed to be done for every minitest test suite include:
>
> * rename MiniTest::Unit::TestCase to Minitest::Test
> * change require 'minitest/unit' (or 'test/unit') to require 'minitest/autorun'
> * delete MiniTest::Unit.autorun (or use Minitest.autorun)
>
> For some really simple test suites that might be enough. Look at the changes done in Rails 4.1[3]
> or in my own little gem[4] for how the necessary changes may look like. For the others some additional
> changes might be required.
>
> Another problem are gems that depends on Gem::TestCase (like RubyGems plugins)
> since Gem::TestCase is inherited from MiniTest::Unit::TestCase. I guess this can't be easily
> solved at the moment, but we probably don't have many gems like that, or are we?
>
> So what do you think of this change? Should we address it by updating upstream test suites?
> Do you know about other issues that this can cause and I forgot to mention?
