Question

我有一个公开Websocket / SockJS / Stomp服务器端点的应用程序，并希望运行一个JUnit测试来运行客户端（Java STOMP客户端，也来自Spring），以测试＆＃34;发送＆＃34;特征

我有一个像

这样的测试

 public void measureSpeedWithWebsocket() throws Exception {
    final Waiter subscribeWaiter = new Waiter();

    new Thread(() -> {
        // Prepare connection
        WebsocketClient listener = new WebsocketClient("/mytopic/stomp");
        try {
            listener.connectAndSubscribe();
            subscribeWaiter.resume();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }).start();
    subscribeWaiter.await(); // Wait for connection.

这里我使用来自https://github.com/jhalterman/concurrentunit的Waiter，其效果基本上是延迟测试的主线程直到辅助线程调用resume（）。 这可能是错误的，因为在上下文中运行的Spring服务器必须做出反应

我收到以下错误

我怎样才能进行适当的测试？＃34;自我连接＆＃34;到我的Spring Boot应用程序提供的websocket？

如果您使用的是Spring Boot而不是幸运者:)。下面是一个示例http://rafaelhz.github.io/testing-websockets/如何测试Web套接字，它在Spring Boot中完美运行，可以为您提供很多帮助。我试图在Spring MVC中做同样的事情，但不幸的是，这在Spring MVC中不起作用。

从JUnit测试自连接到Websocket Spring服务器
