test.h

A very simple, light weight, header only C unit test framework.

Features

• Easy to use, no dependencies, no setup needed.
• Keep test cases close to the code they test.
• Automatic registration of the test cases.

Setup

Just include the header

#include "test.h"

To enable the test cases in your code, compile your program with -DUNIT_TEST.

Defining test cases

TEST_CASE(test_case_name) {
	// Your code here
	// ...
	SHOULD_EQUAL(1, 0); // Fail
}

Run the test cases

In your main function, call run_tests:

int main() {
	// necessary setup code
	// ...
#ifdef UNIT_TEST
	run_tests();
	// cleanup
#endif
	// usual code
}
