JerseyTest如何使用SpringBoot的上下文进行测试

Question

我的 SpringBoot 中有一些 @Component 和 @Resource em> 应用程序。 我有正确的 JDBC 数据源，还有一些 REST 服务，由 Jersey 提供。 我想测试其中一项服务，但它会失败，它说：

自动装配依赖注入失败

但它不使用任何组件。

这是一个测试 db 的简单测试，它正在工作：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = MyApplication.class)
public class CommonRepositoryTest {

    @Autowired
    private MyRepository myRepository;

    @Test
    public void testDatabaseChangeLogsSize() {
        int resultSize = myRepository.getTableRowSize(MyTable.TABLE_NAME);
        System.out.println("MyTable result list size: "+resultSize);
        assertTrue("MyTable table should has at least one row!", resultSize>0);
    }

}

但是这个 REST 测试器不工作：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = MyApplication.class)
public class SampleResourceTest extends JerseyTest {

    @Override
    protected Application configure() {
        ApplicationContext context = new AnnotationConfigApplicationContext(MyApplication.class);
        return new ResourceConfig(SampleResource.class).property("contextConfig", context);
    }

    @Test
    public void testSampleGet() throws Exception {
        long id = 1;
        String name = "name";
        SampleDomainModel sampleDomainModel = new SampleDomainModel();
        sampleDomainModel.setId(id);
        sampleDomainModel.setName(name);
        Response response = target("/sampleresource/samplepath/" + id).queryParam(name).request().get(Response.class);
        SampleDomainModel responseSampleDomainModel = response.readEntity(SampleDomainModel.class);
        assertEquals(sampleDomainModel.getId(), responseSampleDomainModel.getId());
    }

}

如您所见，它必须覆盖 JerseyTest 中的 configure() 方法。 我认为问题在于，AnnotationConfigApplicationContext 可能无法加载任何内容（？）。 @SpringApplicationConfiguration(classes = MyApplication.class) 注解会加载上下文，但 new AnnotationConfigApplicationContext(MyApplication.class) strong> 代码可能会失败，它没有完整的上下文。

如果我用模拟替换代码，它可以工作（但这不是一个好方法）：

@Override
protected Application configure() {
    ApplicationContext mockContext = Mockito.mock(ApplicationContext.class);
    return new ResourceConfig(SampleResource.class).property("contextConfig", mockContext);
}

失败信息是：

这个球衣测试如何使用 SpringBoot 上下文？

Answer 1

简单地说，你不能同时使用 Spring 的 TestContext 和 Jersey 测试框架。他们将在两个不同的ApplicationContexts 上运行。即使您尝试将ApplicationContext（创建为TestContext）注入测试类并在configure 方法中将其传递给ResourceConfig，也为时已晚，因为直到 在 构造之后，但`configure 方法被调用在 构造中。

忘记JerseyTest，直接使用@WebIntegrationTest。请参阅 Spring Boot 项目中的 the sample。

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(SampleJerseyApplication.class)
@WebIntegrationTest(randomPort = true)
public class SampleJerseyApplicationTests {

    @Value("${local.server.port}")
    private int port;

在 Jersey/Boot 环境中，Jersey 需要在 Web 应用环境中运行，这就是 @WebIntegrationTest 所做的。

对于客户端，您只需在JerseyTest 上调用target，您只需创建客户端

Client client = ClientBuilder.newClient();
WebTarget target = client.target("http://localhost:" + this.port);

Response response = target.path("/sampleresource/samplepath/" + id).request().get();
