[ruby-talk:444776] [ANN] minitest 6.0.2 Released

minitest version 6.0.2 has been released!

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.

Features/Problems:

  • minitest/autorun - the easy and explicit way to run all your tests.
  • minitest/test - a very fast, simple, and clean test system.
  • minitest/spec - a very fast, simple, and clean spec system.
  • minitest/benchmark - an awesome way to assert your algorithm's performance.
  • minitest/pride - show your pride in testing!
  • minitest/test_task - a full-featured and clean rake task generator.
  • Incredibly small and fast runner, but no bells and whistles.
  • Written by squishy human beings. Software can never be perfect. We will all eventually die.

Changes:

6.0.2 / 2026-02-23

  • 7 bug fixes:

  * Added missing drb dependency from minitest-server. (y-yagi)   * Cleaned up bisect's sub-commands to load files directly, not ruby+require.   * Fixed bisect to use same cmd ($0) to run tests as original invocation.   * load server_plugin if server is loaded. (y-yagi)   * Manipulate local args instead of ARGV in Sprint.run.   * Only show --bisect in usage if using minitest.   * Remove -Itest:lib from bisect's rb_flags since bin/minitest adds them.
