Constructor Details

This class inherits a constructor from Minitest::Runnable

Class Method Details

.i_suck_and_my_tests_are_order_dependent! ⇒ Object

Call this at the top of your tests when you absolutely positively need to have ordered tests. In doing so, you’re admitting that you suck and your tests are weak.

  class << self
    undef_method :test_order if method_defined? :test_order
    define_method :test_order do :alpha end
  end
end

.make_my_diffs_pretty! ⇒ Object

Make diffs for this Test use #pretty_inspect so that diff in assert_equal can have more details. NOTE: this is much slower than the regular inspect but much more usable for complex objects.

  define_method :mu_pp, &:pretty_inspect
end

.parallelize_me! ⇒ Object

Call this at the top of your tests when you want to run your tests in parallel. In doing so, you’re admitting that you rule and your tests are awesome.

  include Minitest::Parallel::Test
  extend Minitest::Parallel::Test::ClassMethods
end

.runnable_methods ⇒ Object

Returns all instance methods starting with “test_”. Based on #test_order, the methods are either sorted, randomized (default), or run in parallel.

  end
end

.test_order ⇒ Object

Defines the order to run tests (:random by default). Override this or use a convenience method to change it for your tests.
