junit – 集成测试基于Spring Boot的微服务

我已经阅读了很多关于使用 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,我还没有看到任何有关如何对使用/依赖其他Spring Boot应用程序的Spring Boot应用程序进行单元测试的示例,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：

ServiceMediator,
适配器1,
适配器2

ServiceMediator根据输入调用Adapter1或Adapter2.

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

解决方法

process-exec-maven-plugin可能会有所帮助,因为它允许在预集成测试阶段启动多个java进程(作为标准的Spring Boot应用程序),并且它会在集成后测试阶段自动关闭它们.

注意：集成测试应该在集成测试阶段运行,因为maven-failsafe-plugin应该配置spring-boot-maven-plugin see.
然后运行我们的集成测试验证或更高的maven生命周期应该成为目标,因为集成测试阶段实际上位于包之间并验证Lifecycles see Default Lifecycles.

以下maven(pom.xml)配置对我有用：

在test.java文件夹中有一个Integration Test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());
    }
}
