是否可以模拟Android Camera类？

@Override
public void setUp() {
    _camera = Mockito.mock(Camera.class);
}

无法生成模拟(Mockito的createProxyClass中的ExceptionInitializerError).

我应该在相机周围创建一些包装器(不是我最喜欢的解决方案,真的很想嘲笑这个类……)？

或者,我应该使用不同的模拟库然后Mockito？

希望有人能指出我正确的方向.

完成ExceptionInitializerError的堆栈跟踪

解决方法:

在你的stacktrace中,注意子字符串“.CglibMockMaker”：这就是问题所在. CGLib不适用于android – 有一个Mockito专用于Android的插件,它使用dexmaker,就像CGLib一样但是适用于dalvik.只是搜索dexmaker mockito,你应该走在正确的道路上.

您仍然无法模拟Camera.open()(静态工厂方法),但您可以围绕它重构代码.重要的是Camera不是最后一堂课;其余的只是测试的笨拙管道,你应该接受作为编写经过良好测试的Android应用程序的税.
