Question

我从http://en.wikibooks.org/wiki/Ruby_Programming/Unit_testing复制了一个非常简单的单元测试。

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：

Warning: you should require 'minitest/autorun' instead.
Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'

可能出现什么问题？

Answer 1

Test :: Unit :: TestCase已弃用，有利于Minitest :: Test。如果你想让你的例子工作，你需要改变一些事情：

将require "test/unit"替换为require "minitest/autorun"
将Test::Unit::TestCase with替换为Minitest::Test

Ruby unittest错误：＆＃34;你应该要求minitest / autorun＆＃39;代替＆＃34。
