CXF unit testing - junit

Question

I am using Apache CXF 3.0.0 and have few services defined with JAX-RS configuration. We have hierarchical configuration with Spring Framework. These input/output of these services are JSON strings.
I am searching for a working example of Junit test cases to validate my services. Also configure the test in Maven Build.
I referred https://cwiki.apache.org/confluence/display/CXF20DOC/JAXRS+Testing
Is it recommended approach?
Nevertheless, I tried to setup but could not succeed, could not understand how to wire it.

I like the approach you mention in your link, but it depends on your set up.
I show how I managed to create junit test for cxf server using spring configuration:
// Normal Spring Junit integration in my case with dbunit
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = { "classpath:/root-test-context.xml", "classpath:/rest-test-context.xml" })
#TestExecutionListeners({ DependencyInjectionTestExecutionListener.class, DbUnitTestExecutionListener.class })
#DatabaseSetup("AuthenticationResourceTest-dataset.xml")
#DatabaseTearDown("AuthenticationResourceTest-dataset.xml")
public class AuthenticationResourceTest {
// This variable is populated from surfire and reserve port maven plugin
#Value("#{systemProperties['basePath'] ?: \"http://localhost:9080/api/\"}")
private String basePath;
// I assume that you have in your spring context the rest server
#Autowired
private JAXRSServerFactoryBean serverFactory;
private Server server;
#Before
public void beforeMethod() {
serverFactory.setBindingId(JAXRSBindingFactory.JAXRS_BINDING_ID);
// Specify where your rest service will be deployed
serverFactory.setAddress(basePath);
server = serverFactory.create();
server.start();
}
#Test
public void authenticateTest() throws Exception {
// You can test your rest resources here.
// Using client factory
// AutenticationResourceclient = JAXRSClientFactory.create(basePath, AutenticationResource.class);
// Or URLConnection
String query = String.format("invitation=%s", URLEncoder.encode(invitation, "UTF-8"));
URL url = new URL(endpoint + "/auth?" + query);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
try (InputStream is = connection.getInputStream();) {
String line;
// read it with BufferedReader
BufferedReader br = new BufferedReader(new InputStreamReader(is));
while ((line = br.readLine()) != null) {
System.out.println(line);
}
} catch (Exception e) {
e.printStackTrace();
}
}
#After
public void afterMethod() {
server.stop();
server.destroy();
}
}
You need to have in your maven pom.xml

<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-http-jetty</artifactId>
<version>3.0.2</version>
</dependency>
