* Monkey-patch built-sorts to force them to be unstable in all Rubies. Some rubies (such as MRI >= 2.2) have stable sorts, which can cause the tests to pass erroneously. See https://stackoverflow.com/a/44486562/238886 for more about sort stability in Ruby * Set the random number seed in order to make tests repeatable. Since the tests sort relatively short arrays, random chance would sometimes cause erroneous test failures. * Some tests checked that Ruby's built-in sort is unstable. Those checks were moved into their own sections and expanded. Now every Ruby built-in sort method is tested for to ensure that it is unstable.
