minunit

The entire framework is contained in one header file, eliminating build system dependencies and making integration as simple as a #include.

Provides core assertions like mu_check, mu_assert, and equality checks for ints, doubles, and strings, covering common testing needs without bloat.

Works with any C/C++ compiler and only requires standard libraries, making it ideal for embedded systems, cross-platform projects, or environments with strict dependency controls.

Reports test counts, assertion counts, failures, and execution time (real and process), giving clear, immediate feedback on test runs.
