junit - 集成测试基于 Spring Boot 的微服务

Question

我已经阅读了许多关于使用 Spring Boot 和 RESTful 服务的指南，其中许多包含有关运行单元测试的信息，最着名的是“使用 Spring Boot 构建应用程序”。但是，我还没有看到任何示例说明如何对使用/依赖于其他 Spring Boot 应用程序的 Spring Boot 应用程序进行单元测试，这在云微服务架构中很常见。因此，例如，我们有以下 Spring Boot 服务:

服务中介，
适配器 1,
适配器 2

ServiceMediator 根据输入调用 Adapter1 或 Adapter2。

在 Spring JUnit 测试中启动和测试 ServiceMediator 之前，有没有办法启动 Spring Boot 服务 Adapter1 和 Adapter2？

Answer 1

process-exec-maven-plugin 可能会有所帮助，因为它允许在 pre-integration-test 阶段启动多个 java 进程(作为标准 Spring Boot 应用程序)，并且它会在 post-integration-test post-integration-test 阶段自动关闭它们。 _0x104

注:集成测试应在集成测试阶段运行的 Maven的故障保护，插件应 Spring 启动了Maven插件 see进行配置。
然后运行我们的集成测试 验证 或更高版本的 maven Lifecycle 应该是目标，因为 集成测试 阶段实际上位于 包和 50x104567919 包之间的 _407910 _407070x701070x10705700x10705702010000000000000000000000000000000000007

以下 maven (pom.xml) 配置对我有用:

在 test.java 文件夹中有一个集成测试类( WebServerIT ):

import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = WebServerApp.class)
@WebIntegrationTest("server.port:0")
public class WebServerIT {

    @Autowired
    private WebApplicationContext webServerAppContext;

    private MockMvc webServerMockMvc;

    @Before
    public void setUp() {
        System.out.println("the test is set up");
        webServerMockMvc = MockMvcBuilders.webAppContextSetup(webServerAppContext).build();
    }

    /**
     * This test calls the WebServer's endpoint (/accounts/123456789) which in turn calls the micro-service rest api 
     * which is started using the process-exec-maven-plugin, otherwise the test would fail.
     */
    @Test
    public void testWebServerInteractionWithMicroService() throws Exception {
        this.webServerMockMvc.perform(get("/accounts/123456789"))
                .andExpect(status().isOk());
    }
}
