Description​

C++ source file with implementations for the µTest++ methods.

This source file contains the implementations of the utility functions for the µTest++ framework. It provides extract_file_name(), which strips the folder path from a file path returning only the base name, and is_match(), which performs wildcard pattern matching with * (any sequence of characters) and ? (any single character) support.

All definitions reside within the micro_os_plus::micro_test_plus::utility namespace.

This file must be included when building the µTest++ library.
