Description

Problem:
Tests that manipulate external file resources need to guarantee resource integrity and availability. Test suite design and maintainability may suffer from the addition of assurance steps to guarantee parallel execution scenarios and resource leakage from failed previous executions.

Solution:
The use of @tempdir annotation assures a temporary directory being created and cleaned up for every test method execution, thus simplifying test maintenance steps.

Using this approach, we will not create a redundancy build/test/tmp file under zookeeper/zookeeper-server directory, and we also don't need to remove the target file manually
