Y para comunicarte usando WebSockets con tu backend probablemente usarías las utilidades de tu frontend.

O podrías tener una aplicación móvil nativa que se comunica con tu backend de WebSocket directamente, en código nativo.

O podrías tener alguna otra forma de comunicarte con el endpoint de WebSocket.

Pero para este ejemplo, usaremos un documento HTML muy simple con algo de JavaScript, todo dentro de un string largo.

        assertEquals(0, problems.getErrors().size());
        assertEquals(1, problems.getWarnings().size());
