[英]Problems with Testing Jersey 3 Web Application using Jersey Test Framework
I've got a Jersey 3 Web application (running on Tomcat10, JDK15 with JUnit5) in which I would like to Unit test my Endpoints.我有一个 Jersey 3 Web 应用程序(在 Tomcat10、JDK15 和 JUnit5 上运行),我想在其中对我的端点进行单元测试。
Although, I have troubles setting these up.虽然,我在设置这些时遇到了麻烦。 What I understand is, that I need to use a GrizzlyWebTestContainer in order to get the correct environment setup.我的理解是,我需要使用 GrizzlyWebTestContainer 才能获得正确的环境设置。 Also, I figure I need somehow to pass my web.xml to the ServletcContainer.另外,我想我需要以某种方式将我的 web.xml 传递给 ServletcContainer。 But how would I do this?但是我该怎么做呢?
When I run the test, I get:当我运行测试时,我得到:
java.lang.NullPointerException: Cannot invoke "org.glassfish.jersey.test.spi.TestContainer.getBaseUri()" because the return value of "org.glassfish.jersey.test.JerseyTest.getTestContainer()" is null
So I need to configure somewhere a baseUri as well - but where?所以我也需要在某个地方配置一个 baseUri - 但是在哪里? Unfortunately, I've found only examples and documentations with Grizzly Test ContainerFactory instead of GrizzlyWebTestC... Could someone explain me what I did miss?不幸的是,我只找到了 Grizzly Test ContainerFactory 而不是 GrizzlyWebTestC 的示例和文档......有人能解释一下我错过了什么吗?
Any input is much appreciated!非常感谢任何输入!
This is my Unit test:这是我的单元测试:
public class SimpleTest extends JerseyTest {
@Override
public TestContainerFactory getTestContainerFactory() {
return new GrizzlyWebTestContainerFactory();
}
@Override
public DeploymentContext configureDeployment() {
return ServletDeploymentContext
.forServlet(new ServletContainer()) //how to pass web.xml here?
.build();
}
@Override
protected Application configure() {
return new ResourceConfig(DatasetController.class);
}
@Test
public void test() {
Response response = target("/data/180").request().get(); //--> NPE is thrown here
assertEquals(200, response.getStatus());
}
}
This my Endpoint, I would like to test:这是我的端点,我想测试:
@Path("/data")
public class DataController {
@Context ServletContext context;
private DataSource ds;
@PostConstruct
public void init() { ds = (DataSource) context.getAttribute(DATASOURCE_CONTEXT_NAME); }
@GET
@Path("/{dataId}")
@Produces(MediaType.APPLICATION_JSON)
@RolesAllowed({"1","2"})
public Response getDataById(@PathParam("id") Long id) throws SQLException {
logger.debug("Fetching dataset with id " + id);
DSLContext create = DSL.using(ds.getConnection());
//some JOOQ code
return Response.ok(dto).build();
}
}
This is the most important part in my pom.xml这是我 pom.xml 中最重要的部分

This issue causes because in org.glassfish.jersey.test.JerseyTest class you can find method with @Before annotation related to junit4这个问题是因为在 org.glassfish.jersey.test.JerseyTest class 你可以找到与 junit4 相关的 @Before 注释的方法
@Before
public void setUp() throws Exception {
..
}
When you replace junit4 to junit5 this annotation do nothing and method doesn't invoke.当您将 junit4 替换为 junit5 时,此注释不执行任何操作,并且不会调用方法。
Solution:解决方案:
public class YourJerseyTest extends JerseyTest {
@BeforeEach
void init() throws Exception {
super.setUp();
}
..
}
