如何在Serenity集成测试之前启动Spring Boot服务？

Question

我用谷歌搜索了很多，但我没有找到我的问题的适当解决方案。所以也许在这里。

有一个Spring Boot服务，我想在构建时通过REST API进行测试。因此，在执行集成测试之前，需要在构建阶段将服务作为独立服务执行。我可以以某种方式执行它，但不是理想的。

我做了类似于this article的事情

我有一个关于这个pom的maven项目：

我为测试执行创建了一个入口点：

@RunWith(CucumberWithSerenity.class)
@CucumberOptions(
        features = "src/it/resources/features",
        glue = "my.project.package.integrationtest",
        plugin = {
                "pretty"
        },
        tags = "(not @Ignore) or (not @Manual) or (not @ToBeImplemented)"
)
@ActiveProfiles("integration-test")
public class IntegrationTestRunner {}

我有一个启动应用程序的StepsBase类：

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = RANDOM_PORT)
@ActiveProfiles("integration-test")
@ContextConfiguration(classes = Application.class)
public class StepsBase {
    public static final String HOST = "http://localhost:";

    @LocalServerPort
    private int serverPort;

    public String getBaseUrl() {
        return  HOST + serverPort;
    }
}

我的所有steps类都像这样扩展了StepsBase类

public class SimpleSteps extends StepsBase {

    @Given("this is a sample step")
    .
    .
    .
}

如果我使用maven clean verify执行服务构建，那么我将获得以下集成测试日志：

这个解决方案的主要问题是，第一个场景是在实例化step类之前执行Spring Boot服务，这会计入执行时间，如果服务没有启动，测试用例不会受到影响。顺便说一句，每个场景之前的Serenity都会检查服务是否正在运行。

你知道如何让服务在Serenity启动之前启动吗？还是在第一步执行之前？

如果所有内容都在同一个项目(或maven模块)中，您可以使用Spring Boot Maven插件(https://docs.spring.io/spring-boot/docs/current/maven-plugin/usage.html)。示例配置如下所示：

            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.1.4.RELEASE</version>
                <configuration>
                    <classifier>exec</classifier>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>pre-integration-test</id>
                        <goals>
                            <goal>start</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>post-integration-test</id>
                        <goals>
                            <goal>stop</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
    ```
