Question

Article#to_archive是Article#archived!的别名：

class Article
  alias to_archive archived!
end

我需要确保这一点，所以我写了这个测试：

describe '#to_archive' do
  it 'is an alias to #archived!' do
    expect(subject.method(:to_archive)).to eq(subject.method(:archived!))
  end
end

但是，我收到错误

Failure/Error: expect(subject.method(:to_archive)).to eq(subject.method(:archived!))

   expected: #<Method: Article(#<Module:0x00000005a7c240>)#archived!>
        got: #<Method: Article(#<Module:0x00000005a7c240>)#to_archive(archived!)>

它曾用于ruby＆lt; 2.3 IIRC。我试过了alias_method，但没有用。

Answer 1

Method#==的定义不明确和/或有用，所以你不应该依赖它。

要检查它是否为别名，您可以执行以下操作：

expect(subject.method(:to_archive).original_name).to eq(:archived!)

检查方法是否是rspec中另一个方法的别名
