RubyKoans：破损的公牛？

Question

可能是我想知道如果这个问题是在公案（而不是我）一个业余的迹象，但是，考虑这个公案

def test_calling_global_methods_without_parentheses 
    result = my_global_method 2, 3 
    assert_equal __, result 
    end 

注意，my_global方法是

def my_global_method(a,b) 
    a + b 
end 

这是提示它给了我在终端

The answers you seek... 
    <"FILL ME IN"> expected but was <5>. 

所以我做

def test_calling_global_methods_without_parentheses 
    result = my_global_method 2, 3 
    assert_equal 5, result 
    end 

，我得到这个错误

Users/mm/Sites/koans/about_methods.rb:21:in `eval': (eval):1: syntax error, unexpected tINTEGER, expecting keyword_do or '{' or '(' (SyntaxError) 
assert_equal 5, my_global_method 2, 3 
           ^

    from /Users/mm/Sites/koans/edgecase.rb:470:in `block in <top (required)>' 

有谁知道这个问题，或者你可以告诉我如何跳过一个公案？

哦，我测试了这个koan。如果您注意到错误是在第21行，而不是“test_calling_global_methods_without_parentheses”方法。这是“test_sometimes_missing_parentheses_are_ambiguous”方法出错，因为它应该是。您需要纠正该方法。

def test_calling_global_methods_without_parentheses 
    result = my_global_method 2, 3 
    assert_equal 5, result   # You're fine with this koan. 
end 

# (NOTE: We are Using eval below because the example code is 
# considered to be syntactically invalid).     
def test_sometimes_missing_parentheses_are_ambiguous 
    eval "assert_equal 5, my_global_method 2, 3" # ENABLE CHECK 
    # **LOOK HERE~~~ HERE IS THE ERROR YOU SEE** Just correct it. 

如果有任何你不知道如何处理的koan，只是评论它。
