类名称：PowerMockito
方法名：mockStatic

PowerMockito.mockStatic介绍

[英]Creates a class mock with some non-standard settings.

The number of configuration points for a mock grows so we need a fluent way to introduce new configuration without adding more and more overloaded PowerMockito.mockStatic() methods. Hence MockSettings.

mockStatic(Listener.class, withSettings() 
.name("firstListner").defaultBehavior(RETURNS_SMART_NULLS)); 
);

Use it carefully and occasionally. What might be reason your test needs non-standard mocks? Is the code under test so complicated that it requires non-standard mocks? Wouldn't you prefer to refactor the code under test so it is testable in a simple way?

See also Mockito#withSettings()
[中]使用一些非标准设置创建类mock。
模拟的配置点数量在增加，因此我们需要一种流畅的方式来引入新的配置，而不需要添加越来越多的重载PowerMockito。mockStatic（）方法。因此，模拟设置。

mockStatic(Listener.class, withSettings() 
.name("firstListner").defaultBehavior(RETURNS_SMART_NULLS)); 
);

小心使用，偶尔使用。您的测试需要非标准模拟的原因可能是什么？被测代码是否如此复杂，以至于需要非标准模拟？难道你不喜欢重构被测试的代码，让它以一种简单的方式进行测试吗？
另见Mockito#with settings（）
