ctests

This is a simple unit testing framework for C programs.

The library is contained in a single header file (tests.h) that contains both the definitions and implementation of the test runner.

Exactly one implementation is required.

To use the provided runner, in one file, define TESTS_H_IMPLEMENTATION before the #include:

#define TESTS_H_IMPLEMENTATION
#include "tests.h"

For any other file, simple #include "tests.h", then use the test macro instead of a regular function call.

For example:

int test_add(void) {
  return add(1,1) == 2;
}

// Replace with...

#include "tests.h"

test(add) {
  return add(1,1) == 2;
}

Compile and run using:

$ cc -o testrunner *_test.c && ./testrunnner

You are free to implement your own test runner by writing main().
