minitest version 5.11.0b1 has been released!

Published 2017-12-20 @ 18:13

minitest provides a complete suite of testing facilities supporting TDD, BDD, mocking, 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/mock by Steven Baker, is a beautifully tiny mock (and stub) object framework.

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. :P

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.

Changes:

5.11.0b1 / 2017-12-20

  • 2 major enhancements:

    • Added Minitest::Result and Minitest::Result.from(runnable).
    • Changed Minitest::Test to subclass Result and refactored methods up.
  • 6 minor enhancements:

    • Added –no-plugins and MT_NO_PLUGINS to bypass MT plugin autoloading. Helps with bad actors installed globally.
    • Added bench_performance_{logarithmic,power} for spec-style benchmarks. (rickhull)
    • Minitest.run_one_method now checks for instance of Result, not exact same class.
    • Minitest::Test.run returns a Result version of self, not self.
    • ProgressReporter#prerecord now explicitly prints klass.name. Allows for fakers.
    • Removed Runnable.marshal_dump/load.
  • 4 bug fixes:

    • Object.stub no longer calls the passed block if stubbed with a callable.
    • Object.stub now passes blocks down to the callable result.
    • Pushed Minitest::Test#time & #time_it up to Runnable.
    • Test nil equality directly in assert_equal. Fixes #679. (voxik)
