I have a legacy application, which is working with third-party web service through JAX-RPC. Now I need to unit-test the application by mocking certain XML RPC calls with test data. Actually, I need to replace Apache Axis, which is used by the application, by some other library that will be JAX-RPC compliant, but will return what I'm telling it to return. I'm pretty sure I'm not alone with such a problem... Are there any open source libraries for this purpose?
You can do it with Spring framework and EasyMock.
What's the best mock framework for Java?
I have had some success with WireMock. It's a Jetty server that you set up programmatically to respond to certain request patterns with content that you also specify. I have been able to set it up to respond to XML-RPC requests from my class. E.g.,
stubFor(post(urlEqualTo("/RPC2"))
.withRequestBody(containing("<methodName>...</methodName>"))
.willReturn(aResponse()
.withBody("<methodResponse>...</methodResponse>")));
For Mocking the calls to external services you can use EasyMock+Powermock or Mockito
you can do something like this
Easymock.expect(your function calling external Systems).andReturn(your required output)
hope this helps!
Good luck!

I have a class AMSClient, which I want to simulate using WireMock. I have seen some examples but I couldn't understand them, as they are using port numbers. Can any one tell me how to simulate a class using WireMock.
WireMock isn't an object mocking tool. If you're looking to mock a class or interface I'd suggest looking at Mockito.
However, if the class/interface in question wraps HTTP calls to another service, then WireMock can help by mimicking the HTTP responses from the service.
Using power mockito concept, I solved this issue

How do you guys Test your SOAP Services? Do you use Tools like soapUI or do you write Unit Tests?
Just wanted to hear some opinions, what you prefer, what the advantages or disadvantages of both approaches are? And if someone writes Unit Tests, can you give me an example how to write those???
Edit: I developed a lot of REST services, which I usually tested using JUnit and a REST Client Framework. So when the REST Service was deployed, I was able to invoke those services with as a JUnit Test using a http connection. Is there something similiar in SOAP too? Does anyone have an example code for a SOAP Client?
The best way to test your SOAP service is by using the SOAPUI testing tool.
With JDEF you can create your SOAP Application, following SOAP standards - and then easily verify this through the Enterprise Manager Console provided by Oracle.
You just get an instance of that particular service, and then you can see the audit flow.
I use both Junit for functional low-level testing of my functions and back end code. And I use SOAPUI to test the Web Service. Also keep in mind that you can run SOAPUI tests from within unit tests as desribed here. example:
public void testRunner() throws Exception
{
SoapUITestCaseRunner runner = new SoapUITestCaseRunner();
runner.setProjectFile( "src/dist/sample-soapui-project.xml" );
runner.run();
}
If you like to test services you can use SOAPUI tool which is easy. But if you like to test service's functions are wroking right or not, you need to right unitest. That means if you are the author of the webservice, you might need to write unittests to check the functionalities.
I'm using both. Basically JUnit for simple automated unit tests. And SoapUI for more complex system tests which make more that a single web service call.
I've written a small library which does most of the heavy lifting of unit-testing SOAP services. Basically you'll get mockito mocks which are easy to work with.
I am working on a Java project that is split up into a web project and a back-end project. The web talks to the back-end via web service calls.
There is one class in the web project that makes all of the web service calls and I would like to add testing around this class. I want to do unit testing, and not functional testing, so I do not want to have to have the web service actually running to run the tests. If this class were simply passing the calls through to the back-end, I might be willing to overlook testing it, however there is caching happening at this point, so I want to test that it is working correctly.
When the web service is generated jax-ws wsgen it creates an interface that the front end uses. I have used this generated interface in order to create a fake object for testing. This works pretty well, but there are issues with this approach.
I am currently the only one on my team that is doing unit testing, and so am the only one maintaining the test code. I would like to be able to have the test code be built when the rest of the code is built, but if someone else introduces a new method into one of the web service classes, then the interface will have the new method on it, and my fake object will not implement it, and will therefor be broken.
The web and the back end code projects are not dependent on one another, and I do not want to introduce a dependency between them. So, introducing an interface on top of the web service endpoint does not seem plausible since if I put it in the back-end, my web code needs to reference it, and if I put it in the front-end, my back-end code needs to reference it. I also cannot extend the endpoint since this will also introduce a dependency between the projects.
I am unfamiliar with how web services work, and how the classes are generated for the web project to be able to refer to them. So, I do not know how to create an interface in the back end that will be available for me to use in the web project.
So, my question is, how would I get the interface available to my front-end project without introducing a project dependency (in Eclipse build path)? Or, is there another, better way to fake out the back-end web service that I am calling?
First off, I'd break out the caching code into a testable unit that does not directly depend upon the web service calls.
As for the web services, I find it useful to have both functional tests that exercise the web services and other tests that mock out the web services. The functional tests can help you find edge cases that your mocks may miss.
For instance, I'm using Axis2 and generating stubs from the WSDL. For the mocks, I just implement or extend the generated stubs. In our case the real web service is implemented by an outside organization. Probing their web service through exploratory functional tests has revealed some exceptions that needed to be handled that were not apparent by just examining the generated stubs. I used this information to better mock these edge cases.
I have a public EJB class that I want accessible online as a web service. I have generated a WSDL and the SOAP mesasging seems to work. I used soapUI to test the connection. What I'm not clear about is how would I then use this exposed web service. I'd like to try another language like Python to then make calls through that interface. I know that the WSDL is supposed to help a potential client build it's client side code but I'm not sure about how to specify the connection and location and login information if I had that. I know I'm asking a large topic but any information would help. Thanks
Edit: so basicaly I'm just wondering do I have to use tools to generate my client code from the WSDL like axis2. Or whatever Python uses. Or can I write the code by hand? What's generally done. is the server reference included in that WSDL and are call methods generated usually?
Take a look at ZSI
But ZSI is too complex and spends more time to generate proxies
I suggest you to use suds. suds generates the proxies On the fly and so fast, i used it in some projects.
another packages are available:
soaplib
SOAPy
pysimplesoap
Im a Newbie in wsdl parsing and my information about WSDL is very limited.
I have a scenario in which there is a wsdl file with multiple operations and i want to get the wsdl for a specific operation from that. Is there any libs in java or JS to accomplish such a task . Or am i missing something.
Please correct me if there is anything wrong in the question ,
Thanks in Advance

WSDLs represent a single service with specific operations. Those operations belong to the service can't be separated from the service itself. In order to simply invoke one method you'll have to bind against the entire service (and all other operations and defined types). If you are publishing the operation, you'll have to bind and publish all operations and types defined in the service. There isn't really a way around that.
Now, in your case if you are using java and if you are acting as a client, you can do what Alfredo O alluded to and use a SOAP framework's tooling to generate all of the java client code for you. From there it's just a matter of using the actual service class and invoking the method on that class that corresponds to the method you want to call. You'll have to use the entire wsdl, but from the perspective of your code you won't have to worry about calling any other methods than the one that interests you.
Popular choices for generating a java client for a SOAP service are:
Apache CXF
Metro
Apache Axis2
You can use Axis 2 to auto-generate the java code needed to invoke those operations. Use the wsdl2java tool provided by Axis 2.
