minitest provides a complete suite of testing facilities supporting
TDD, BDD, and benchmarking.
"I had a class with Jim Weirich on testing last week and we were
allowed to choose our testing frameworks. Kirk Haines and I were
paired up and we cracked open the code for a few test
frameworks...
I MUST say that minitest is *very* readable / understandable
compared to the 'other two' options we looked at. Nicely done and
thank you for helping us keep our mental sanity."
-- Wayne E. Seguin
minitest/test is a small and incredibly fast unit testing framework.
It provides a rich set of assertions to make your tests clean and
readable.
minitest/spec is a functionally complete spec engine. It hooks onto
minitest/test and seamlessly bridges test assertions over to spec
expectations.
minitest/benchmark is an awesome way to assert the performance of your
algorithms in a repeatable manner. Now you can assert that your newb
co-worker doesn't replace your linear algorithm with an exponential
one!
minitest/pride shows pride in testing and adds coloring to your test
output. I guess it is an example of how to write IO pipes too. 
minitest/test is meant to have a clean implementation for language
implementors that need a minimal set of methods to bootstrap a working
test suite. For example, there is no magic involved for test-case
discovery.
"Again, I can't praise enough the idea of a testing/specing
framework that I can actually read in full in one sitting!"
-- Piotr Szotkowski
Comparing to rspec:
rspec is a testing DSL. minitest is ruby.
-- Adam Hawkins, "Bow Before MiniTest"
minitest doesn't reinvent anything that ruby already provides, like:
classes, modules, inheritance, methods. This means you only have to
learn ruby to use minitest and all of your regular OO practices like
extract-method refactorings still apply.

Oh god... here we go... (again)
* 8 deaths in the family(!!):
* Deleted MiniTest and MiniTest::Unit::TestCase compatibility namespaces.
* Deleted all use of Marshal for serialization.
* Deleted maglev? and rubinius? guard methods. LOL.
* Deleted all minitest/spec expectations from Object. Use _/value/expect.
* Dropped minitest/mock.rb. This has been extracted to the minitest-mock gem.
* assert_equal(nil, value) no longer allowed. Use assert_nil to be explicit.
* Removed assert_send. Use assert_predicate or assert_operator.
* Removed Minitest::Test#class_name.
* 7 major (oft incompatible) changes:
* Big: Major refactored MT6's run path!
* Minitest.__run -> Minitest.run_all_suites
* Runnable.run -> Runnable.run_suite & Runnable.filter_runnable_methods
* Runnable.run_one_method -> Runnable.run
* Removed Minitest.run_one_method (might bring it back to raise?)
* Removed deprecated ENV["N"] to specify number of parallel tests. Use MT_CPU.
* Renamed options[:filter] to options[:include], added --include cmdline option.
* --name is still handled, but that will be removed in the future.
* Renamed Minitest::Runnable#test_order to #run_order.
* If #message is passed a proc then that proc overrides all other output.
* They are no longer chained!
* And it does less for formatting of your output.
* Removed reporter arg from with_info_handler as it has never(?) been used. (HACK?)
* Plugin loading is now opt-in!
* Require the plugin in your test_helper.
* Or use Minitest.load :x
* Or call Minitest.load_plugins for the old autoloading behavior.
* 5 additions:
* Added minitest-sprint's minitest cmdline, now with line support!
* Added minitest-bisect. Run with minitest --bisect or -b.
* Added minitest-server.
* Added minitest/complete to help with shell's tab-completion of tests.
* Vendored latest version of path_expander.
* 5 other:
* Bumped to ruby 3.2+.
* Removed obsolete conditional for CompositeReporter#prerecord.
* Removed obsolete version guards around Minitest::Result in reporters.
* assert_operator and assert_predicate both call assert_respond_to first.
* Assertions reuse themselves a lot more. Bumps assertion count in some places.
