Junit ConcurrentTestRunner和@ClassRule

Question

我如何通过JUnit（例如具有100个线程）与ResourceRulesRule（dropwizard）和DAOTestRule之类的ClassRules结合执行并行测试？我认为我必须为每个线程创建新的ResourceTestRule，对吗？我将ResourceTestRule实例的创建移至myTest方法，但出现了nullPointerException。...

示例：

@RunWith(ConcurrentTestRunner.class)
public class ConcurrenceTest {    
String TOKEN = "blabla";
@Rule
public DAOTestRule myDatabase =
    DAOTestRule.newBuilder().addEntityClass(MyEntity.class).build();

private static MyManager myManager = new MyManager(myDatabase);

@ClassRule
public static final ResourceTestRule resources = ResourceTestRule.builder()
    .addProvider(RolesAllowedDynamicFeature.class).addProvider(new AuthDynamicFeature(OAUTH_HANDLER))
    .addProvider(new AuthValueFactoryProvider.Binder<>(AccessTokenPrincipal.class))
    .addProvider(new JerseyViolationExceptionMapper()).addProvider(new JsonProcessingExceptionMapper())
    .addResource(new MyResource(MyManager)).build();


@Test
@ThreadCount(100)
public void myTest() {

MyRequest myRequest = new MyRequest(1, "abc");

Response response = resources.target("/things").request().header("Authorization", TOKEN)
        .post(Entity.json(myRequest));
}
}
