java - 安卓模拟相机

Question

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)。

我是否应该在 Camera 周围创建某种包装器(这不是我最喜欢的解决方案，我真的只想模拟类...)？

或者，我应该使用与 Mockito 不同的模拟库吗？

希望有人能给我指出正确的方向。

答案来晚了，但这里有一个适用于 Android 的模拟相机示例。

您可以将 VideoFileInputSource 设置为从视频文件模拟相机

textureVideoInputSource = new VideoFileInputSource(this, "mock_input_video.mp4");

或者您可以为视频流启用硬件摄像头。

textureVideoInputSource = new CameraTextureVideoInputSource(this);
