Question

How do I test a “resource” in a Spring Controller:

@RequestMapping(value = "/{query}", method = RequestMethod.GET)
public @ResponseBody String getResource(
        HttpServletRequest req, 
        HttpServletResponse res,
        @PathVariable String query,
        @RequestParam(value="param1", required = false) String param1,
        @RequestParam(value="param2", required = false) String param2) throws SomeException{
    return service.read(query);
}

And since I am developing with App Engine I have a JUnit scaffolding like this:

@ContextConfiguration(locations = { "classpath:service/client-config.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
public class LocalDatastoreTest {
    private final LocalServiceTestHelper helper =
            new LocalServiceTestHelper(new LocalDatastoreServiceTestConfig());  

    @Before
    public void setUp() {
        helper.setUp();
    }

    @After
    public void tearDown() {
        helper.tearDown();
    }   

    @Test
    public void test() {

    }

}

If you have a test server up and running,
try using Spring RestTemplate in your test method

something like:

RestTemplate restTemplate = new RestTemplate();
String result = restTemplate.getForObject("YOUR_URL/{query}", String.class,"myQuery");

See more here.

If you don’t have a server and need basic unit testing, try mocking one.
