Check if Redis port is available or not. if not, try to assign a different port

Use the @DirtiesContext annotation on each test class thus it tells the testing framework to close and recreate the context for later tests.

As it turns out, The MessageListenerAdapter uses the RedisSerializer.string() as the default serializer. This means that any POJO other than a String in the parameter list of the listener method will be ignored. In order to get past this, you need to invoke the setSerializer method and pass in RedisSerializer.java() as the argument. This will let the MessageListenerAdapter know that the POJO is a java class and needs to be serialized/deserialized. Please note that whatever pojo that you decide to pass in MUST implement java.io.Serializable. Please see the example below, and hopefully this helps someone else.

The issue appears to have been the spring-boot-email-core

There is currently no built-in support for achieving this.

For further details see the Close all ApplicationContexts in the TestContext framework after all tests have been executed issue in Spring Framework's issue tracker.

Currently, the only way to properly close an ApplicationContext cached by the Spring TestContext Framework is via @DirtiesContext or a custom TestExecutionListener that invokes TestContext#markApplicationContextDirty(...)
