How to test method alias ruby

Question

How to test if if method has an alias?

Let\'s say we have

Class Test
  class << self
    def a;end
    alias :b :a
  end
end

Answer 1

You can set a result to your function to check if result is same.

def a
  return 'test string'
end

then it { expect(Test.b).to eq(Test.a) }

is it ok?
