It seems your test is based on HttpBindingTest in the http-binding quickstart. Does the HttpBindingTest itself work for you? If it works, what is the difference between HttpBindingTest and yours?
I found the issue. I thought the system property can be used for both REST binding and HTTP Binding. Actually, my binding is REST binding, so in order to create a embedded REST binding with specific port I use these 2 properties:
System.setProperty("org.switchyard.component.resteasy.standalone.port", "8082"); System.setProperty("org.switchyard.component.resteasy.standalone.path", "");
