在 ASP.NET Core 中模拟 IHttpConnectionFeature

Question

嗨，我想在 ASP.NET Core 中模拟 IHttpConnectionFeature

在我的控制器中，我有：

var connectionId = HttpContext.Features.Get<IHttpConnectionFeature>().ConnectionId;

但是我如何在我的单元测试中模拟它：

        var controller = new MyController(logger.Object,
            mockService.Object)
        {
            ControllerContext = new ControllerContext
            {
                HttpContext = new DefaultHttpContext()
            }
        };

我收到一条错误消息：

消息 = "未将对象引用设置为对象的实例。"

你可以像这样添加它：

controller.HttpContext.Features.Set<IHttpConnectionFeature>(new HttpConnectionFeature()
{
     ConnectionId = "test"
});
