我已经将我的springboot应用程序从2.1.6.realease更新到了2.4.4，现在我的单元测试不再工作了。
堆栈跟踪是：

问题似乎发生在这里：

@Rule
 public final transient Pipeline pipeline = TestPipeline.create();

我跟踪了stacktrace最后在 ObjectMapper:1065 . 您在那里找到的代码是：

public static List<Module> findModules(ClassLoader classLoader)
    {
        ArrayList<Module> modules = new ArrayList<Module>();
        ServiceLoader<Module> loader = secureGetServiceLoader(Module.class, classLoader);
        for (Module module : loader) { // This is line 1065
            modules.add(module);
        }
        return modules;
    }

处理for each循环似乎有问题。我找了很多，但找不到解决这个问题的办法。
通常我使用的是java8。我试着将我的windows更新到java11，但是错误仍然出现。
我在这里附上了pom.xml：

在另一个测试中也有一个错误。但似乎每个人都有一个问题：

也许其他人也有这个问题。我对beam、flink和spring都很陌生。很抱歉，如果这可能是一个简单的配置错误。
ps：我把junit4测试迁移到junit5。
任何帮助都很好
提前谢谢

看来我找到了这个问题的答案。解决这个问题很困难，花了我一整天的时间。
所以我上面的问题不止一个：
第一个问题：
所以问题似乎出在 beam-runners-flink 以及 spring-kafka-test .
所以我改变了主意 pom.xml 并添加

<dependency>
        <groupId>org.apache.beam</groupId>
        <artifactId>beam-runners-flink-1.11</artifactId>
        <version>${apache.beam.version}</version>
        <exclusions>
            <exclusion>
                    <groupId>org.scala-lang</groupId>
                    <artifactId>scala-library</artifactId>
                </exclusion>
        </exclusions>
</dependency>

所以呢 beam-runners-flink 使用 scala-libary:1.11 默认情况下。 spring-kafka-test 使用 scala-libary:1.13 . 因此scala 1.11的实现不同于1.13，这两个包之间存在冲突。
不包括scala beam-runners-flink 解决了问题，然后所有代码都是根据scala 1.13编译的。
第二个问题
apachebeam不支持junit5（感谢@danieloliveira提供了这个信息）。但是Spring2.4强制使用junit5。所以他们在一起发生了冲突。参考Spring2.4的发行说明，您需要启用junit4测试。
把这些放在一起似乎是解决我问题的办法。

不幸的是，apachebeam还不支持junit5。在撰写本文时，有一个jira问题和一个正在进行的请求。但目前，您需要恢复到JUnit4进行ApacheBeam测试。
