groovymap forced in python
原标题:groovy map coercion in python

我是Python的相对新手,我只是想知道是否有类似于Groovy中可用的map coercion功能的等效功能。

为了上下文,我正在编写一个单元测试并想模拟一个只有两个简单方法接口的类,用 Groovy 可以这样做:

mock = [apply:{value -> return value*2 }, isValid:{return true}]
testObject.applyMock(mock)

即,模拟可以被视为具有类似的对象:


class mock:

    def apply(self, value):
        return value *2

    def isValid(self):
        return true

有一种漂亮的Python方式实现这个吗?

Cheers Alex

问题回答

使用 type() 的3参数形式:

mock = type( mock , (object,), { apply : (lambda self, value: value * 2),
   isValid : lambda self: True})
