@TempDir in JUnit 5

@TempDir is an annotation that is used to annotate the fields in a test class of a test method of the type of path or file that should be resolved to the temporary directory, it is introduced in junit5 for the management of temporary directories in the test scenarios. This annotation allows programmers and developers to declare the parameter in the test method. If we use the annotation JUnit should automatically create a temporary directory and provide the path of the directory during the execution of the Annotated method.

@TempDir annotation handles the temporary file-related operations and ensures a clean and simplified environment for each test case.

Now let us understand the steps involved in implementing the Junit 5 @TempDir annotation.

Junit 5 is a Unit testing framework for the Java programming language. It is a simple framework for writing tests for Java codes using Java. Whenever we write code, we have to test it. Junit is the primary source for writing the test cases. the latest version of Junit is Junit 5 Jupiter.
