Question

Like the title says whenever I run my integration tests with the Jersey Test Framework they pass when I do one test at a time. When I do a clean and build on my project it passes some tests but fails on two or three.

A message body reader for Java class com.foo.Result, and Java type class com.foo.Result, and MIME media type application/octet-stream was not found

My web service resource has a @Produces and @Consumes annotation on the methods and do not understand why it some pass and others fail when the code is basically the same.

A snippet of the web resource:

@Path("/data")
@RolesAllowed({"upload"})
@Component
@Scope("request")
public final class UploadData {

   @POST
   @Consumes("application/vnd.foo.data-v1.0.0+xml")
   @Produces("application/xml")
   public Response uploadData(final Data data) {
        // Processes the data and returns the response
        return getResponse(data, null);
   }
}

All my integration tests have something like this:

ClientResponse response = resource().path("123_10").entity(getData(), "application/vnd.foo.data-v1.0.0+xml").post(ClientResponse.class);
Result result = response.getEntity(Result.class); // Seems to fail on this line for some tests

Here is the main test class that my other test classes inherit from:

public abstract class AbstractRestTest {

    private static final String PACKAGE = UploadData.class.getPackage().getName();
    private static JerseyTest jerseyTest;
    private Data data;

    /**
     * Initializes the Jersey Test to use for testing.
     */
    @BeforeSuite
    public final void init() {
        jerseyTest = new JerseyTest(new WebAppDescriptor.Builder(PACKAGE)
                     .contextPath("rest").contextParam("contextConfigLocation",
                     "classpath:testApplicationContext.xml")
                     .servletClass(SpringServlet.class)
                     .contextListenerClass(ContextLoaderListener.class)
                     .requestListenerClass(RequestContextListener.class).build()) {
        };
    }

   /**
    * Gets the Jersey Test client.
    *
    * @return - the Jersey Test client.
    */
    public final Client client() {
        return jerseyTest.client();
    }

    /**
     * Gets the Jersey Test web resource.
     *
     * @return - the Jersey Test web resource.
     */
    public final WebResource resource() {
       return jerseyTest.resource().path("data");
    }

    /**
     * Sets up the necessary code to run the tests.
     *
     * @throws Exception if it cannot set up the test.
     */
    @BeforeTest
    public final void setUp() throws Exception {
        jerseyTest.setUp();
        data = new Data();
    }

    /**
     * Tears down the resources after the tests.
     *
     * @throws Exception if it cannot tear down the test.
     */
    @AfterTest
    public final void tearDown() throws Exception {
        jerseyTest.tearDown();
    }

    /**
     * Get the data.
     *
     * @return - the data.
     */
    public final Data getData() {
       return data;
    }

    /**
     * Set the data.
     *
     * @param theData - the data.
     */
     public final void setData(final Data theData) {
        this.data = theData;
     }

Answer 1

Solved it! Cannot have any code in the setup method in the AbstractRestTest. Once I removed it and only called the JerseyTest.setup() all my unit tests passed.

/**
 * Sets up the necessary code to run the tests.
 *
 * @throws Exception if it cannot set up the test.
 */
@BeforeTest
public final void setUp() throws Exception {
    jerseyTest.setUp();
    data = new Data(); // Removed and set it in the tests I needed it to be in, this was the problem having this line before or after the jerseyTest.setup()
}
