Ruby unittest错误：“你应该要求’minitest / autorun’。”
我有一个非常简单的unit testing，我从http://en.wikibooks.org/wiki/Ruby_Programming/Unit_testing复制。
require_relative "simple_number" require "test/unit" class TestSimpleNumber < Test::Unit::TestCase def test_simple assert_equal(4, SimpleNumber.new(2).add(2) ) assert_equal(6, SimpleNumber.new(2).multiply(3) ) end end 执行此代码会导致错误：

可能有什么问题？
不推荐使用Test :: Unit :: TestCase，而选择Minitest :: Test。 如果你想让你的例子工作，你需要改变一些事情：
- 用
require "minitest/autorun"替换require "test/unit"require "minitest/autorun" - 用
Minitest::Test替换Test::Unit::TestCase with
