Ruby 在RSpec中没有实际断言的代码?
我是Ruby新手,在各种开源软件中,我注意到一些RSpec描述中的一些“语句”似乎没有达到他们的目的,比如他们想做一个断言,但没有。是这些编码错误还是我缺少了一些RSpec或Ruby魔法?(异常重载运算符的可能性?) 示例,带#???添加到可疑行: (rubinius/spec/ruby/core/array/permutation\u spec.rb) (chef/spec/unit/chef_fs/parallelizer.rb)Ruby 在RSpec中没有实际断言的代码?,ruby,rspec,Ruby,Rspec,我是Ruby新手,在各种开源软件中,我注意到一些RSpec描述中的一些“语句”似乎没有达到他们的目的,比如他们想做一个断言,但没有。是这些编码错误还是我缺少了一些RSpec或Ruby魔法?(异常重载运算符的可能性?) 示例,带#???添加到可疑行: (rubinius/spec/ruby/core/array/permutation\u spec.rb) (chef/spec/unit/chef_fs/parallelizer.rb) context”With:ordered=>false(无序

我认为没有任何特殊行为。我认为您在测试代码中发现了错误。这不起作用,因为没有断言,只有比较:
@numbers.permutation(9).entries.size==0
它需要写成:
@numbers.permutation(9).entries.size.should==0
或者使用较新的RSpec语法:
expect(@numbers.permutation(9.entries.size.))to eq(0)
很难确定这些行的目的是什么(调试遗留下来的?有人想创建断言,但没有完成?)。它们不是真正的bug,因为它们对示例是否会失败或通过没有任何影响(只要它们引用的方法存在)。但除此之外,这些行只是无用的代码。。。

@numbers.permutation(9).entries.size == 0 #???
@numbers.permutation(9) { |n| @yielded << n }
@yielded.should == []
