我有一个单元测试,我必须模拟一个返回bool类型的非虚方法

public class XmlCupboardAccess
{
    public bool IsDataEntityInXmlCupboard(string dataId,
                                          out string nameInCupboard,
                                          out string refTypeInCupboard,
                                          string nameTemplate = null)
    {
        return IsDataEntityInXmlCupboard(_theDb, dataId, out nameInCupboard, out refTypeInCupboard, nameTemplate);
    }
}

所以我有一个XmlCupboardAccess类的模拟对象,我试图在我的测试用例中为这个方法设置mock,如下所示

[TestMethod]
Public void Test()
{
    private string temp1;
    private string temp2;
    private Mock<XmlCupboardAccess> _xmlCupboardAccess = new Mock<XmlCupboardAccess>();
    _xmlCupboardAccess.Setup(x => x.IsDataEntityInXmlCupboard(It.IsAny<string>(), out temp1, out temp2, It.IsAny<string>())).Returns(false); 
    //exception is thrown by this line of code
}

但是这条线引发了异常

Invalid setup on a non-virtual (overridable in VB) member: 
x => x.IsDataEntityInXmlCupboard(It.IsAny<String>(), …
