mockito如何创建模拟对象的实例 [英] How does mockito create an instance of the mock object

问题描述

当我创建一个类Employee的模拟对象。它不调用Employee对象的构造函数。我知道内部Mockito使用CGLIb和反射，创建一个代理类，将类扩展到mock。如果它不调用employee的构造函数，那么如何创建employee类的mock实例？

When i create a mock object of say class Employee. It doesnt call the constructor of Employee object. I know internally Mockito uses CGLIb and reflection, creates a proxy class that extends the class to mock. If it doesnt call the constructor of employee how is the mock instance of employee class created ?

推荐答案

Mockito使用CGLib生成类对象。但是，要实例化此类对象，它使用Objenesis http://objenesis.org/tutorial.html

Mockito uses CGLib to generate class object. However to instantiate this class object it uses Objenesis http://objenesis.org/tutorial.html

Objenesis能够使用各种技术（即调用ObjectStream.readObject等）来实例化没有构造函数的对象。

Objenesis is able to instantiate object without constructor using various techniques (i.e. calling ObjectStream.readObject and similar).
