问题复现步骤:

  1. 开启相关容器：
#启动order模块里面的测试对应的数据库
$docker run -d --name wxshop-order-Test_mysql -p 3308:3306 -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=order mysql

#启动main模块wxshop数据库
docker run -d --name wxshop_mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=wxshop mysql

#启动main模块测试需要的数据库
docker run -d --name wxshopTest_mysql -p 3307:3306 -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=wxshop mysql

#启动order模块主数据库order
$docker exec -it wxshop_mysql mysql -uroot -proot -e 'create database if not exists `order`'

#启动redis
docker run -d -p 6379:6379 --name=myredis redis

#启动测试用的redis
docker run -p 6380:6379 --name myTestRedis -d redis

#启动zookeeper
$docker run -it -p 2181:2181 zookeeper

2.运行如下命令:(mvn clean verify) 会发现报错信息: [ERROR] Failures: [ERROR] ShoppingCartIntegrationTest.canDeleteShoppingCartData:167 expected: <1> but was: <2> [INFO]

$mvn clean verify
