@SpringBootTest + @BeforeAll

我有一个小型的弹簧启动应用程序，其中包含数据库和rabbymq用法。所以我想用集成测试（H2 + apache qpid）进行测试。

@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, classes = TestSpringConfig.class)
@TestInstance(TestInstance.Lifecycle.PER_CLASS)

正如我的应用程序期望数据库和mq Im使用@BeforeAll来启动它：

@BeforeAll
public void before() {
    startMessageBroker();
    startDatabase();
}

问题是我的 Web 应用在 @BeforeAll 中定义的 database/mq 之前启动。

org.springframework.test.context.junit.jupiter.SpringExtension：

public class SpringExtension implements BeforeAllCallback, AfterAllCallback, TestInstancePostProcessor,
        BeforeEachCallback, AfterEachCallback, BeforeTestExecutionCallback, AfterTestExecutionCallback,
        ParameterResolver {
// ...
    @Override
    public void beforeAll(ExtensionContext context) throws Exception {
        getTestContextManager(context).beforeTestClass();
    }
// ...
    @Override
    public void postProcessTestInstance(Object testInstance, ExtensionContext context) throws Exception {
        getTestContextManager(context).prepareTestInstance(testInstance);
    }
// ...

Web 应用在后进程测试实例阶段启动，并在“全部”之前@BeforeAll方法。

org.junit.platform.engine.support.hierarchical.HierarchicalTestExecutor：

private void execute(TestDescriptor testDescriptor, C parentContext, ExecutionTracker tracker) {
    Node<C> node = asNode(testDescriptor);
    tracker.markExecuted(testDescriptor);

    C preparedContext;
    try {
        preparedContext = node.prepare(parentContext); // 1 <<<
        SkipResult skipResult = node.shouldBeSkipped(preparedContext);
        if (skipResult.isSkipped()) {
            this.listener.executionSkipped(testDescriptor, skipResult.getReason().orElse("<unknown>"));
            return;
        }
    }
    catch (Throwable throwable) {
        rethrowIfBlacklisted(throwable);
        // We call executionStarted first to comply with the contract of EngineExecutionListener
        this.listener.executionStarted(testDescriptor);
        this.listener.executionFinished(testDescriptor, TestExecutionResult.failed(throwable));
        return;
    }

    this.listener.executionStarted(testDescriptor);

    TestExecutionResult result = singleTestExecutor.executeSafely(() -> {
        C context = preparedContext;
        try {
            context = node.before(context); // 2 <<<

            C contextForDynamicChildren = context;
            context = node.execute(context, dynamicTestDescriptor -> {
                this.listener.dynamicTestRegistered(dynamicTestDescriptor);
                execute(dynamicTestDescriptor, contextForDynamicChildren, tracker);
            });

            C contextForStaticChildren = context;
            // @formatter:off
            testDescriptor.getChildren().stream()
                    .filter(child -> !tracker.wasAlreadyExecuted(child))
                    .forEach(child -> execute(child, contextForStaticChildren, tracker));
            // @formatter:on
        }
        finally {
            node.after(context);
        }
    });

    this.listener.executionFinished(testDescriptor, result);
}

请参阅第 1 点和第 2 点。有“准备”的执行，然后是“之前”。

我不确定是 junit，SpringExtension 还是我做错了什么。有什么建议吗？
