C# 视窗电话的测试加速度计实现 问题

我的应用程序通过类使用加速计数据

现在我想编写单元或代码DUI测试，出于这个原因，我需要一个特殊的

加速计测试实现来控制返回的数据

理论上，我有3种选择：

创建
加速计
的子类-不可能，因为
加速计
是
密封的
类
通过在运行时使用反射替换
加速计的实现
，这不是IMHO的最佳选择
创建
SensorBase的子类

您找到了构造函数：

internal SensorBase();

此构造函数防止
SensorBase
具有默认的公共构造函数，并且不能从其程序集外部对此类进行子类化

测试它将是复杂的。您可以重新设计应用程序，并为
加速计使用包装器/适配器
仅用于测试，或者您可以检查是否有可能在Windows Phone上安装
