> *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|https://github.com/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
