een

een is a very minimal unit-testing "framework" written in C and implemented in a single header file. It's handy when you want some real simple unit tests for a small project. een is derived from Minctest.

een implements assertion and equality functions. It tracks and times how many tests pass and fail. Failed tests also display which line the failing test code was on.

Features

• ISO C99 with no dependencies
• Single header file
• Reports file and line number for failed assertions
• Reports run-time for each test
• Tests continue even after an assertion fails
• Assertions for float, integer, and string equality

Example

    #include "een.h"

    void test1(void)
    {
      lok('a' == 'a');
    }

    void test2(void)
    {
      lequal(5, 5);
      lfequal(5.5, 5.5);
      lsequal("abc", "abc");
    }

    int main(void)
    {
      lrun("test1", test1);
      lrun("test2", test2);
      lresults();
      return lfails != 0;
    }

That produces the following output:

            test1:
             -- pass: 1                    fail: 0                    time: 12ms
            test2:
             -- pass: 3                    fail: 0                    time: 0ms
    ALL TESTS PASSED (4/4)

Hints

All functions and variables start with the letter 'l'.
