在ruby和rspec中处理来自混入模块外部的方法

module MyModule
  def my_method
    puts "This is a method from MyModule"
  end
end

class MyClass
  include MyModule
end

obj = MyClass.new
obj.my_method # 输出：This is a method from MyModule

module MyModule
  def my_method
    puts "This is a method from MyModule"
  end
end

obj = Object.new
obj.extend MyModule

obj.my_method # 输出：This is a method from MyModule

module MyModule
  def my_method
    puts "This is a method from MyModule"
  end
end

RSpec.describe MyClass do
  include MyModule

  it "should call my_method" do
    my_method # 输出：This is a method from MyModule
  end
end
