NullPointerExceptions throws while Arquillian and PowerMockito test runs

nkovalenko93 Jun 23, 2015 8:48 AM

Good day. I have a problem with using Arquillian with PowerMock. I wanna test jax-rs service, but I get two NPEs when test starts. NullPointerException throws when PowerMockRule field defined. My test:

@RunWith(Arquillian.class)
@PowerMockIgnore({"javax.management.*", "javax.xml.parsers.*",
    "com.sun.org.apache.xerces.internal.jaxp.*", "ch.qos.logback.*", "org.slf4j.*"})
public class ResourceRequestServiceIsAvailableIT {
 
    private static final Logger LOGGER = LoggerFactory
                                               .getLogger(ResourceRequestServiceIsAvailableIT.class);
 
    @Rule
    public PowerMockRule        rule   = new PowerMockRule();
 
 
    @Deployment(testable = true)
    public static Archive<?> createDeployment() {
        final WebArchive war = ShrinkWrap
                .create(WebArchive.class, "resourceRequestIsAvailableTest.war")
                // .addAsResource("persistence-test.xml", "META-INF/persistence.xml")
                .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml")
                .addAsWebInfResource("wildfly-ds.xml")
                .addAsResource("functionalId.properties")
                .addAsResource("logback-test.xml", "logback.xml")
                .addAsResource("xml/organizationalUnit.xml")
                .addAsResource("xsd/organizationalUnit.xsd")
                .addAsResource("xml/resourceRequest.xml")
                .addAsResource("xsd/resourceRequest.xsd")
                .addClass(ResourceRequestRestService.class)
                .addPackages(true, "by.iba.gomel.domain")
                .addPackage("by.iba.gomel.restws.logging")
                .addPackages(true, "org.apache.commons.io")
                .addAsLibraries(
                        Maven.resolver().resolve("org.kie.remote:kie-remote-client:6.2.0.Final")
                        .withTransitivity().asFile())
                .addAsLibraries(
                        Maven.resolver().resolve("org.aspectj:aspectjrt:1.8.5").withTransitivity()
                                .asFile());
        ResourceRequestServiceIsAvailableIT.LOGGER.info("generated .war file - "
                + war.toString(true) + "\n");
        return war;
    }
 
    @Test
    public void testStartResourceRequest() { 
        final ResteasyClient client = new ResteasyClientBuilder().build();
        final ResteasyWebTarget target = client.target("http" + "://" + "localhost" + ":" + "8080"
                + "/resourceRequestIsAvailableTest" + "/rest/resourcerequest/startResourceRequest");
        final Form form = new Form();
        try {
            form.param("rr", IOUtils.toString(ResourceRequestServiceIsAvailableIT.class
                    .getResourceAsStream("/xml/resourceRequest.xml")));
        } catch (final IOException e) {
            ResourceRequestServiceIsAvailableIT.LOGGER.error(
                    MarkerFactory.getMarker(LoggerConstants.EXCEPTION_LOG_MARKER.getString()),
                    "Problem reading ResourceRequest XML", e);
        }
        try {
            form.param("ou", IOUtils.toString(ResourceRequestServiceIsAvailableIT.class
                    .getResourceAsStream("/xml/organizationalUnit.xml")));
        } catch (final IOException e) {
            ResourceRequestServiceIsAvailableIT.LOGGER.error(
                    MarkerFactory.getMarker(LoggerConstants.EXCEPTION_LOG_MARKER.getString()),
                    "Problem reading OrganizationalUnit XML", e);
        }
        final Response response = target.request().post(Entity.form(form));
        ResourceRequestServiceIsAvailableIT.LOGGER.info(
                "Request successfully sent, response is '{}'", response.getStatusInfo());
        response.close();
    }
}

My service method:

@POST
    @Path("/startResourceRequest")
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    public Response postAll(final MultivaluedMap<String, String> form) {
 
        final URL baseUrl;
        ResourceRequest resourceRequest = null;
        try {
            final JAXBContext jaxbContext = JAXBContext.newInstance(ResourceRequest.class,
                    OrganizationalUnit.class);
            final Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
            resourceRequest = (ResourceRequest) unmarshaller.unmarshal(new StringReader(form
                    .getFirst("rr")));
            baseUrl = new URL("http://localhost:8084/kie-wb");
        } catch (final JAXBException | MalformedURLException e) {
            ResourceRequestRestService.LOGGER.error(
                    MarkerFactory.getMarker(LoggerConstants.EXCEPTION_LOG_MARKER.getString()),
                    "System problem, check the log", e);
            return Response.status(Status.INTERNAL_SERVER_ERROR)
                    .entity("System problem, check the log").build();
        }
 
        if (form.containsKey("userId")) {
            this.user = form.getFirst("userId");
            this.password = form.getFirst("password");
        }
        if ((this.user == null) || this.user.isEmpty()) {
            ResourceRequestRestService.LOGGER.error(
                    MarkerFactory.getMarker(LoggerConstants.EXCEPTION_LOG_MARKER.getString()),
                    "Failed to provide authentication data");
            return Response.status(Status.INTERNAL_SERVER_ERROR)
                    .entity("Failed to provide authentication data").build();
        }
 
        final RuntimeEngine engine = RemoteRuntimeEngineFactory.newRestBuilder()
                .addDeploymentId(ResourceRequestRestService.DEPLOYMENT_ID).addUrl(baseUrl)
                .addUserName(this.user).addPassword(this.password)
                .addExtraJaxbClasses(ResourceRequest.class).build();
        final KieSession ksession = engine.getKieSession();
        final Map<String, Object> processParams = new HashMap<>();
        processParams.put("resourceRequest", resourceRequest);
        ksession.startProcess("Interview.ResourceRequest", processParams);
 
        return Response.status(Status.OK).entity("Business process 'Resource Request' started")
                .build();
    }
