Junit 为什么每次都会重新创建带有RabbitMQ的测试容器，而不是在测试之间共享

我有4个监听器测试，应用程序构建在SpringBoot上并使用Testcontainers，我运行mvn clean install，我得到以下结果：

9-08-15 18:37:01.287  INFO 8312 --- [tContainer#1-11] o.s.a.r.c.CachingConnectionFactory       : Attempting to connect to: [localhost:33724]

我向mvn clean install命令的日志文件输出了一个结果，在整个日志中多次出现上述情况，但这不是主要问题，问题是带有RabbitMQ的容器多次启动，我希望在测试之间共享它

2019-08-15 18:35:26.126信息---[main]JUnit中的ClassRule将按类而不是按“套件”执行规则。因为您有多个扩展它的测试类，所以在测试期间可以启动多个容器

考虑使用和检查
