为什么这个测试不通过？

Question

调试这个Ruby单元测试时遇到了麻烦，但无法弄清楚我做错了什么。这是代码：

我的问题是best_sentence_choice方法;这是Textmate回归给我的：

    require 'test/unit.rb'
require 'wordplay.rb'

class TestWordPlay < Test::Unit::TestCase

  def test_sentences
    assert_equal(["a", "b", "c d", "e f g"], "a.b. c d. e f g".sentences)

    test_text = %q{Hello. This is a test
      of sentence separation. This is the end of the test.}
      assert_equal("This is the end of the test", test_text.sentences[2])
end

def test_words
  assert_equal(%w{this is a test}, "this is a test".words)
  assert_equal(%w{these are mostly words}, "these are, mostly, words".words)
end

# Testing best sentence choice
def test_sentence_choice
  assert_equal('This is a great test')
              WordPlay.best_sentence(['This is a test', 'This is another test', 'This is a great test']
              %w{test great this}))
  assert_equal('This is a great test', WordPlay.best_sentence(['This is a great test'],
                                                                %w{'still the best'}))

end                                                                            
end

以下是Textmate的回复：

    /Users/pdenlinger/ruby/wordplaylib/wordplaytest.rb:23: syntax error, unexpected tQWORDS_BEG, expecting ')'
              %w{test great this}))
                 ^
/Users/pdenlinger/ruby/wordplaylib/wordplaytest.rb:23: syntax error, unexpected ')', expecting kEND
              %w{test great this}))
                                  ^

你能帮忙吗？谢谢！

Answer 1

在这一行

WordPlay.best_sentence(['This is a test', 'This is another test', 'This is a great test'] %w{test great this}))

在第一个参数之后，您似乎没有逗号。然后有两个结束括号，但你只有一个开放的肠胃外。

请考虑编辑您的问题以使代码更具可读性（提示：如果一行以4个空格开头并且前面有空行，则它看起来像代码）。
