我embedded-cassandra在我的单元测试（Scalatest）中使用。当我尝试批量运行所有测试用例时，出现错误

An exception or error caused a run to abort: Unable to start EmbeddedCassandra[name='cassandra-2', version='3.11.6']
...
Caused by: java.io.IOException: 'WindowsCassandraNode[pid='-1', exitValue='0']' is not alive. Please see logs for more details

我可能做错了什么？正如跟踪所说cassandra-2，似乎另一个 Cassandra 实例已经在运行？会不会是测试同时运行？串行运行测试的方法是什么Intellij/Scalatest？

这个答案提到 Scalatest 会并行运行西装，这可能会导致端口冲突问题。有没有办法避免端口冲突embedded-cassandra或串行运行套件？-如何在ScalaTest 中按顺序运行类中的测试？

You can try to use random ports to solve your issue:

EmbeddedCassandraFactory cassandraFactory = new EmbeddedCassandraFactory();
cassandraFactory.setPort(0);
cassandraFactory.setSslPort(0); // if SSL client options enabled
cassandraFactory.setRpcPort(0);
cassandraFactory.setJmxLocalPort(0);
cassandraFactory.setStoragePort(0);
cassandraFactory.setSslStoragePort(0); // // if SSL server options enabled
