我还有最后一节课，大概是这样的:
public final class RainOnTrees{
public void startRain(){
// some code here
}
}
我在其他一些类中使用这个类，像这样:
public class Seasons{
RainOnTrees rain = new RainOnTrees();
public void findSeasonAndRain(){
rain.startRain();
}
}
在我的JUnit测试类Seasons.java中，我想模拟RainOnTrees类。我怎么能用Mockito做到这一点?
当前回答
在Mockito 3和更多的我有同样的问题，并修复它从这个链接
模拟最终类和方法与Mockito 依下列各项
在Mockito用于模拟最终类和方法之前，需要对它进行>配置。 我们需要在项目的src/test/resources/mockito-extensions目录中添加一个名为org.mockito.plugins.MockMaker的文本文件，并添加一行文本: mock-maker-inline Mockito在加载时检查扩展目录中的配置文件。该文件允许模拟final方法和类。
其他回答
如果您试图在test文件夹下运行unit-test，那么顶部的解决方案是可以的。只要跟着它添加一个扩展。
但如果你想运行与android相关的类，如context或activity，在androidtest文件夹下，答案是你。
为运行mockito成功添加这些依赖项:
testImplementation org.mockito: mockito-core: 2.24.5 testImplementation“org.mockito: mockito-inline: 2.24.5”
Mockito 2现在支持final类和方法!
但就目前而言，这只是一个“孵化”功能。它需要一些步骤来激活它，这些步骤在Mockito 2中的新内容中描述:
Mocking of final classes and methods is an incubating, opt-in feature. It uses a combination of Java agent instrumentation and subclassing in order to enable mockability of these types. As this works differently to our current mechanism and this one has different limitations and as we want to gather experience and user feedback, this feature had to be explicitly activated to be available ; it can be done via the mockito extension mechanism by creating the file src/test/resources/mockito-extensions/org.mockito.plugins.MockMaker containing a single line: mock-maker-inline After you created this file, Mockito will automatically use this new engine and one can do : final class FinalClass { final String finalMethod() { return "something"; } } FinalClass concrete = new FinalClass(); FinalClass mock = mock(FinalClass.class); given(mock.finalMethod()).willReturn("not anymore"); assertThat(mock.finalMethod()).isNotEqualTo(concrete.finalMethod()); In subsequent milestones, the team will bring a programmatic way of using this feature. We will identify and provide support for all unmockable scenarios. Stay tuned and please let us know what you think of this feature!
是的，同样的问题在这里，我们不能模拟一个最终类与Mockito。准确地说，Mockito不能模仿/监视以下内容:
最后的课程 匿名类 原始类型
但是在我看来，使用包装器类代价很大，所以改用PowerMockito。
使用Powermock。这个链接展示了如何做到这一点:https://github.com/jayway/powermock/wiki/MockFinal
