It is necessary to design a set of integration testing solutions for the project, which can better test whether the functions of components such as Nacos, RocketMQ, Seata, Sentinel in the project serve expectations, improve the efficiency of project integration testing, and realize intelligent automatic testing through Github CI

Code branch: integration-test

Project background: Previously in the spring-cloud-alibaba-tests/nacos-old-tests module, based on the @HasDockerAndItEnabled annotation
Execute mvn clean -Dit.enabled=true test in the ci script to execute all unit tests marked with this annotation

Currently we need to plug in our new version of unit tests for nacos and rocketmq whenever a new module needs to be plugged in
Specify the module in spring-cloud-alibaba-tests/spring-cloud-alibaba-testcontainers/pom.xml
The following work needs to be done

1. In the new module spring-cloud-alibaba-tests/intergration/nacos-docker-tests
   To do some nacos coverage tests, you can refer to the unit tests of each module of nacos
   File path: https://github.com/alibaba/nacos/tree/develop/test
   Improve the test coverage of the nacos module

2. In the new module spring-cloud-alibaba-tests/intergration/rocketmq-docker-tests
   Do some coverage tests of rocketmq, you can refer to rocketmq
   File path: https://github.com/apache/rocketmq/tree/develop/test/src/test

3. For the actual use of the user, the mixed use of nacos + rocketmq may occur.

Currently some actions can be predefined in the xxxxTester class
Path: spring-cloud-alibaba-tests/spring-cloud-alibaba-testcontainers/src/main/java/com/alibaba/cloud/integration/common

You can try to start by combining containers to improve coverage
It is expected to do e2e end-to-end testing similar to the following KafkaDebeziumSourceTests
File path: apache/flink@master...complone:flink-hackthon-2021-issue-6

4. If you have spare capacity, you can explore to improve the test coverage in other directions, such as sentinel, seata
