我是 bUnit 的新用户，并设法运行了一些测试NavMenu以掌握基本概念。但是，不同的 Blazor 页面向辅助 signalR 集线器发出请求以进行工作流状态的通信。

如何模拟signalR连接？ https://github.com/dotnet/aspnetcore/issues/14924

使用附加 signalR 连接来传达工作流状态的服务器页面

 protected override async Task OnAfterRenderAsync(bool firstRender)
        {
            if (firstRender)
            {
                var hubUrl = NavigationManager.BaseUri.TrimEnd('/') + "/motionhub";

                try
                {
                    Logger.LogInformation("Index.razor page is performing initial render, connecting to secondary signalR hub");

                    hubConnection = new HubConnectionBuilder()
                        .WithUrl(hubUrl)
                        .ConfigureLogging(logging =>
                        {
                            logging.AddConsole();
                            logging.AddFilter("Microsoft.AspNetCore.SignalR", LogLevel.Information);
                        })
                        .AddJsonProtocol(options =>
                        {
                            options.PayloadSerializerOptions = JsonConvertersFactory.CreateDefaultJsonConverters(LoggerMotionDetection, LoggerMotionInfo, LoggerJsonVisitor);
                        })
                        .Build();

                    hubConnection.On<MotionDetection>("ReceiveMotionDetection", ReceiveMessage);
                    hubConnection.Closed += CloseHandler;

                    Logger.LogInformation("Starting HubConnection");
                    await hubConnection.StartAsync();
                    Logger.LogInformation("Index Razor Page initialised, listening on signalR hub => " + hubUrl.ToString());
                }
                catch (Exception e)
                {
                    Logger.LogError(e, "Encountered exception => " + e);
                }
            }
        }

存根单元测试类

 public class IndexTest : TestContext, IDisposable
    {
        private MotionDetectionRepository repo;

        public IndexTest()
        {
            var mock = new Mock<IMotionDetectionSerializer<MotionDetection>>();
            repo = new MotionDetectionRepository(mock.Object, new NullLogger<MotionDetectionRepository>());

            Services.AddScoped<ILogger<MotionDetectionRepository>, NullLogger<MotionDetectionRepository>>();
            Services.AddScoped<ILogger<MotionInfoConverter>, NullLogger<MotionInfoConverter>>();
            Services.AddScoped<ILogger<MotionDetectionConverter>, NullLogger<MotionDetectionConverter>>();
            Services.AddScoped<ILogger<JsonVisitor>, NullLogger<JsonVisitor>>();
            Services.AddScoped<ILogger<WebApp.Pages.Index>, NullLogger<WebApp.Pages.Index>>();
            Services.AddScoped<IMotionDetectionRepository>(sp => repo);
            Services.AddScoped<MockNavigationManager>();
            Services.AddSignalR();
        }

        [Fact]
        public void Test()
        {
            var cut = RenderComponent<WebApp.Pages.Index>();

            Console.WriteLine($"{cut.Markup}");
        }
    }

我使用这些经纪人。

public interface IHubConnectionsBroker
{
    HubConnection CreateHubConnection(string endpoint, bool autoReconnect);
}

public interface IChatHubBroker
{
    event EventHandler<ChatMessage> OnReceiveMessage;
    event EventHandler<Exception> OnConnectionClosed;
    event EventHandler<Exception> OnReconnecting;
    event EventHandler<string> OnReconnected;

    bool IsConnected { get; }
    string ConnectionId { get; }
    TimeSpan HandshakeTimeout { get; set; }
    TimeSpan KeepAliveInterval { get; set; }
    TimeSpan ServerTimeout { get; set; }
    ChatHubBrokerState ChatHubBrokerState { get; }
    ValueTask StartAsync();
    ValueTask StopAsync();
    ValueTask SendAsync(ChatMessage message);
    ValueTask DisposeAsync();
}
