jp_alloc_test.h

/* jp_alloc_test.h - minimal C test framework for jp_alloc
 *
 * No external dependencies. Provides TEST(), ASSERT_*, RUN_TEST(), DONE().
 * Designed to be included by jp_alloc_test.c which is compiled with
 * -DJP_ALLOC_TEST (providing main()) and links jp_alloc.c in the same
 * translation unit (so static internals are visible for white-box tests).
 *
 * Usage:
 *   TEST(test_foo) {
 *       ASSERT_TRUE(1 == 1);
 *   }
 *   int main(void) {
 *       RUN_TEST(test_foo);
 *       DONE();
 *   }
