+## Unit Testing
+
+For a quick test, there is a special static member function named `CreateTestDirectory`, which will create a test directory, and some files to test encryption.
+> the directory must not exists or test will fail, you can supply how many files you want with init-list argument, here creating a test directory with 2 files, the files will contain a trivial buffer, just for testint purposes.

+// this will return the full path of the directory if successfully created, an empty string otherwise, you can use it's value for later operations like target supply.
+const String_t create_test_dir = Crypto::CreateTestDirectory("/path/to/test/dir", {"file1.txt", "file2.txt"});
