c# - 如何使用模拟匿名类型的设置？

Question

我有以下存储库:

interface IReportingRepository where T: Report
{
     IEnumerable<T> GetReports<T>(object constraints);
}

我正在尝试模拟对这个存储库的调用:

var reportingRepostory = new Mock<IReportingRepository>();
                       reportingRepostory.Setup(x => 
                       x.GetReports<ServiceReport (Moq.It.IsAny<object>())).
                       Returns(new List<ServiceReport>(){Report1, Report2});

但是不是传入

Moq.It.IsAny<object>()

我要传匿名类型

new {Activated = true, Enabled = true}

这样我就可以设置我对使用正确匿名类型的期望。

您可以在反射帮助下使用自定义匹配器:

var reportingRepostory = new Mock<IReportingRepository>();
reportingRepostory
    .Setup(x => x.GetReports<ServiceReport>(HasProperties()))
    .Returns(new List<ServiceReport>(){Report1, Report2});

其中HasProperties方法实现如下:

private object HasProperties()
{
    return Match.Create(
        (object o)  =>
        {
            var properties = o.GetType().GetProperties();
            return properties.Any(p => p.Name == "Available")
                && properties.Any(p => p.Name == "Enabled");
        });
}
