Fixed sequence of tests for suites can lead to interdependency of test cases and burden in maintenance.

I would prefer to test without touching the file system (no matter either it is business logic or serialization code), or if it is inevitable (as for testing integration with file feeds) then would use creating temporary files:

// Create temp file.
File temp = File.createTempFile("pattern", ".suffix");
// Delete temp file when program exits.
temp.deleteOnExit();
