minitest version 5.12.0 has been released!

Published 2019-09-22 @ 16:27

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

 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.


5.12.0 / 2019-09-22

  • 8 minor enhancements:

    • Added a descriptive error if assert_output or assert_raises called without a block. (okuramasafumi)
    • Changed mu_pp_for_diff to make having both \n and \n easier to debug.
    • Deprecated $N for specifying number of parallel test runners. Use MT_CPU.
    • Deprecated use of global expectations. To be removed from MT6.
    • Extended Assertions#mu_pp to encoding validity output for strings to improve diffs.
    • Extended Assertions#mu_pp to output encoding and validity if invalid to improve diffs.
    • Extended Assertions#mu_pp_for_diff to make escaped newlines more obvious in diffs.
    • Fail gracefully when expectation used outside of it.
  • 3 bug fixes:

    • Check option[:filter] klass before match. Fixes 2.6 warning. (y-yagi)
    • Fixed Assertions#diff from recalculating if set to nil
    • Fixed spec section of readme to not use deprecated global expectations. (CheezItMan)
