Test case using SpringJunitRunner - spring

Question

I want to write junit test case for the below code with springJunitRunner.
the below piece of code is one service in a class.
#Component
#Path(/techStack)
public class TechStackResource {
#Autowired
private transient TechStackService techStackService;
#GET
#Path("/{id}")
#Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public Response getTechStackById(final #PathParam("id") Integer technicalstackid) {
final TechStackResponse response = new TechStackResponse();
int statusCode = Constants.HTTP_STATUS_OK_200;
try {
TechStackModel techStackModel = techStackService.findObjectById(technicalstackid);
response.setGetTechStackDetails(GetTechStackDetails.newBuilder().technicalStack(techStackModel).build());
if (techStackModel == null) {
statusCode = Constants.HTTP_STATUS_ERROR_404;
}
} catch (EmptyResultDataAccessException erde) {
} catch (Exception e) {
LOGGER.error("Exception occured in TechStackResource.getTechStackById(technicalstackid) ", e);
throw new APMRestException(
"Exception while executing TechStackResource.getTechStackById(technicalstackid) ",
Constants.UNKNOW_ERROR, e);
}
return Response.status(statusCode).entity(response).build();
}
}
the configuration in web.xml for servlet is
<servlet-name>jersey-servlet</servlet-name>
<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>

Since you are using Jersey as well as Spring, you can use the SpringJunitRunner only to wire-up TechStackResource with its dependency TechStackService.
In order to test your REST handler method getTestStackById, you could go the POJO approach and invoke it directly. Alternatively, you can use Jersey's own MockWeb environment. To find out more about this, I recommend looking at the Jersey example sources, e.g. HelloWorld.
