如何在JerseyTest套件中使用@BeforeClass和@AfterClass

Question

It turns out that JUnit wants @BeforeClass and @AfterClass to be static and this doesn't get along well with JerseyTest's configure method override. Is there a known way to configure the Jersey application while still being able to access JUnit's utility methods?

public class MyControllerTest  extends JerseyTest {
  @BeforeClass
  public static void setup() throws Exception {
    target("myRoute").request().post(Entity.json("{}"));
  }
  @Override
  protected Application configure() {
      return new AppConfiguration();
  }
}

Hence beforeClass needs to be static, target cannot be called because of its instance-method nature. While trying to use the constructor instead, it turns out that configure is run after the constructor and this prevents the setup-request to be executed and will therefor fail naturally.

Any advice is more than appreciated, thanks!

Answer 1

What we did in several cases to avoid heavy setups in such situations is to use a boolean flag to run that setup conditionally.

public class MyControllerTest extends JerseyTest {

  private static myRouteSetupDone = false;

  @Before
  public void setup() throws Exception {
    if (!myRouteSetupDone) {
      target("myRoute").request().post(Entity.json("{}"));
      myRouteSetupDone = true;
    }
  }
  @Override
  protected Application configure() {
      return new AppConfiguration();
  }
}

@Before不需要静态修饰符，并且将在每个测试方法之前执行。
