 // Below, the package filesystem (@file_system_mock.go) furnishes a mock implementation of the FileSystem
 // interface intended for testing. It enables the monitoring of file operations and
 // the emulation of file system interactions without real disk I/O, showcasing the
 // "magic" of Go programming language (🎩🪄).

 // Additionally, it can be utilized for tracking file activities during tests or without tests (as Expert).
