如何使用JMock在Java中模拟静态变量 [英] How to mock a static variable in java using JMock

问题描述

我有一个单元测试问题，其中的一个类有一个静态变量想要加载Spring Application Ctx.

I have a Unit testing problem where a class has a static variable which wants to load the Spring Application Ctx.

此类并非来自Bean Factory，并且我无法更改此事实.

static ApplicationContext applicationContext = ...;

这很好用，但是很难 JMock ，或者至少我不知道一种方法，直到Spring Ctx想要启动为止.对于单元测试情况不是很理想.

This works fine, but is hard to JMock, or atleast I don't know a way and until I can the Spring Ctx wants to start up. Not ideal for a unit test situation.

有没有人知道的解决方法? 我可以选择将static变量更改为所需的任何内容.

Is there a work around that anyone knows? I have the option to change the static variable to anything I wish..

谢谢.

推荐答案

我自己解决了这个问题.

Solved this myself.

最后真的很简单.只是需要将我的静态函数包装在一个我可以模拟的类中.

Was really simple in the end. Justed need to wrap my static in a class which I could then mock.

public class ApplicationContextHolder implements ApplicationContextHoldable {

    protected static ApplicationContext applicationContext = ...;

    @Override
    public ApplicationContext getApplicationContext() {
        return ApplicationContextHolder.applicationContext;
    }

}
