Junit test for spring ws endpoint interceptor - junit

Question

Would appreciate any code examples of how to call a SpringWS endpoint intrceptor from a Junit test class. Particularly on how to prepare a SOAP message context and endpoint object. The SOAP message in the context will need to have a custom SOAP header included.
Something like....
public class MyInterceptorTest
private static String "... my XML SOAP test message ...";
#Test
public testMyInterceptor() {
myMessageContext = ... Build a MessageContext with the XML message string;
myEndPointObject = ... Build an endpoint object;
boolean result = MyInterceptorClass.handleRequest(myMessageContext, myEndPointObject);
... Check results;
}
Any examples would be appreciated.

Answer 1

The MessageContext can be created by instantiating a DefaultMessageContext object. The request WebServiceMessage can created using the test support class PayloadMessageCreator, but this only appeared in Spring-WS 2.x.
The endpoint object can be anything - it depends what your interceptor does with it. If it doesn't actually use it, then you can just pass in null.

I had the same issue and was able to figure it out in part using #skaffman's suggestion.
Basically, I had a custom EndpointInterceptor that I wanted to test with real data so that I would know I had everything correct.
You will have to upgrade spring-ws-test and other spring-ws dependencies to version 2.0 or higher. I ended up using something different than PayloadMessageCreator.
final Source payload = new StreamSource(new StringReader(soapPayload));
SaajSoapMessageFactory saajSoapMessageFactory = new SaajSoapMessageFactory(MessageFactory.newInstance());
WebServiceMessage requestPayload = new SoapEnvelopeMessageCreator(payload).createMessage(saajSoapMessageFactory);
MessageContext messageContext = new DefaultMessageContext(requestPayload, saajSoapMessageFactory);
soapPayload is the string value of an entire soap envelope.
Something similar to this:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
...fill in your custom headers here
</soapenv:Header>
<soapenv:Body><someRequest>...</someRequest></soapenv:Body>
</soapenv:Envelope>
You will obviously need to fill in your request payload, any namespaces, as well as your custom headers.
I set the endpoint object to null as I was not doing anything with it as part of my interceptor.
