Test::File::Cleaner

Test::File::Cleaner is a Perl module that automatically cleans up your filesystem after running tests. This module is extremely useful when writing file-related testing code since it is common for one to end up with many files scattered all over the testing directories. These leftover files become problematic if you repeatedly run the test scripts, which can lead to interference with subsequent test runs. The solution to this problem is to clean up residual files.

Test::File::Cleaner makes the task of cleaning up residual files easier to manage by doing this work at END-time. This ensures that the files are cleaned up even if you break out of the test script while it is running. Maintaining this cleanup code can be cumbersome and time-consuming, but Test::File::Cleaner attempts to solve this problem by simplifying the process.

You create a Cleaner object for a particular directory, and the object scans and stores the contents of the directory. After completing the tests that create files, the Cleaner object cleans up the testing directory. Cleaner cleans up by comparing the original stored state with the current state and removes any new files or directories created during the testing process.

To use Test::File::Cleaner, you can create a cleaner instance which saves the contents of a directory. Then, when you run tests that add files or directories, these new files are added to the instance. Finally, you can force an immediate clean up or wait until the cleaner is DESTROYed when the program exits.

Overall, Test::File::Cleaner is an excellent module for writing file-related testing code, and it significantly simplifies file cleanup after running tests.
