可能是业余爱好者的迹象,我想知道问题是否出在公案(而不是我),但是,考虑一下这个公案
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
这是它在终端中给我的提示
The answers you seek...
<"FILL ME IN"> expected but was <5>.
所以我做了
def test_calling_global_methods_without_parentheses
result = my_global_method 2, 3
assert_equal 5, result
end
我得到了这个错误
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

有谁知道这个问题,或者你能告诉我如何跳过公案吗?
