class Minitest::Test - minitest: Ruby Standard Library Documentation

# class Minitest::Test

Subclass `Test` to create your own tests. Typically you’ll want a `Test` subclass per implementation class.

See `Minitest::Assertions`

### Public Class Methods

i_suck_and_my_tests_are_order_dependent!() click to toggle source

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.

    # File minitest-5.25.4/lib/minitest/test.rb, line 35
    def self.i_suck_and_my_tests_are_order_dependent!
      class << self
        undef_method :test_order if method_defined? :test_order
        define_method :test_order do :alpha end
      end
    end

make_my_diffs_pretty!() click to toggle source

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.

    # File minitest-5.25.4/lib/minitest/test.rb, line 48
    def self.make_my_diffs_pretty!
      require "pp"

      define_method :mu_pp, &:pretty_inspect
    end

parallelize_me!() click to toggle source

Call this at the top of your tests (inside the `Minitest::Test` subclass or `describe` block) when you want to run your tests in parallel. In doing so, you’re admitting that you rule and your tests are awesome.

    # File minitest-5.25.4/lib/minitest/test.rb, line 60
    def self.parallelize_me!
      include Minitest::Parallel::Test
      extend Minitest::Parallel::Test::ClassMethods
    end

runnable_methods() click to toggle source

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

    # File minitest-5.25.4/lib/minitest/test.rb, line 70
    def self.runnable_methods
      methods = methods_matching(/^test_/)

      case self.test_order
      when :random, :parallel then
        srand Minitest.seed
        methods.sort.shuffle
      when :alpha, :sorted then
        methods.sort
      else
        raise "Unknown test_order: #{self.test_order.inspect}"
      end
    end

### Public Instance Methods

run() click to toggle source

Runs a single test with setup/teardown hooks.

    # File minitest-5.25.4/lib/minitest/test.rb, line 87
    def run
      time_it do
        capture_exceptions do
          SETUP_METHODS.each do |hook|
            self.send hook
          end

          self.send self.name
        end

        TEARDOWN_METHODS.each do |hook|
          capture_exceptions do
            self.send hook
          end
        end
      end

      Result.from self # per contract
    end
