可能是业余爱好者的标志,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>.
So I did
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?
哦,我测试了这个公案。如果您注意到的话,错误就在第 21 行,而不是“test_calling_global_methods_without_parentheses”方法。这是“test_sometimes_missing_parentheses_are_ambiguously”方法出了问题,因为它应该是这样。您应该纠正该方法。
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公案,只需评论即可。
