在ASP.NET Core中模拟IHttpConnectionFeature

Question

您好我想在ASP.NET Core中模拟IHttpConnectionFeature

在我的控制器中我有：

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

但我如何在单元测试中模拟它：

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

我收到错误消息：

  

Message =＆＃34;对象引用未设置为对象的实例。＆＃34;

您可以像以下一样添加：

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