Android模拟相机 [英] Android mock Camera

问题描述

是否可以模拟Android相机类？

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

无法生成模拟（ ExceptionInitializerError createProxyClass ）。

我应该在相机（不是我最喜欢的解决方案，真的想只是模拟类...）？

不同的模拟库然后Mockito？

希望有人能指出我的方向正确。

你仍然不能够模拟Camera.open（）（静态工厂方法）但你可以重构你的代码。重要的是，相机不是一个最后的类;其余的只是尴尬的水管测试，你应该只接受作为税务写作经过良好测试的Android应用程序。
 
Is it possible to mock the Android Camera class ?
@Override
public void setUp() {
    _camera = Mockito.mock(Camera.class);
}
fails to generate a mock (ExceptionInitializerError in Mockito's createProxyClass).

Should I create some kind of wrapper around the Camera (not my favorite solution, would really like to just mock the class...)?

Or, should I use a different mock library then Mockito?

Hope somebody can point me in the right direction.

解决方案
In your stacktrace, notice the substring ".CglibMockMaker": that's the problem here.  CGLib doesn't work on android -- there's a plugin for Mockito specifically for android that uses dexmaker, which is like CGLib but works for dalvik.  Just search for dexmaker  mockito and you should be on the right path.

You still won't be able to mock Camera.open() (the static factory method), but you can refactor your code around that.  What matters is that Camera is not a final class; the rest is just awkward plumbing for the test, which you should just accept as the tax for writing well-tested android apps.
