* definitions. To avoid this problem, #define macro TEST_NO_MAIN in all
* compilation units but one.
*/
/* Macro to specify list of unit tests in the suite.
* The unit test implementation MUST provide list of unit tests it implements
* with this macro:
*
* TEST_LIST = {
* { "test1_name", test1_func_ptr },
* { "test2_name", test2_func_ptr },
* ...
* { NULL, NULL } // zeroed record marking the end of the list
* };
*
* The list specifies names of each test (must be unique) and pointer to
* a function implementing it. The function does not take any arguments
* and has no return values, i.e. every test function has to be compatible
* with this prototype:
*
* void test_func(void);
*
* Note the list has to be ended with a zeroed record.

*
* TEST_CHECK takes only one argument (the condition), TEST_CHECK_ allows
* also to specify an error message to print out if the condition fails.
* (It expects printf-like format string and its parameters). The macros
* return non-zero (condition passes) or 0 (condition fails).
*
* That can be useful when more conditions should be checked only if some
* preceding condition passes, as illustrated in this code snippet:
*
* SomeStruct* ptr = allocate_some_struct();
* if(TEST_CHECK(ptr != NULL)) {
* TEST_CHECK(ptr->member1 < 100);

* condition fails, the currently executed unit test is immediately aborted.
*
* That is done either by calling abort() if the unit test is executed as a
* child process; or via longjmp() if the unit test is executed within the
* main Acutest process.
*
* As a side effect of such abortion, your unit tests may cause memory leaks,
* unflushed file descriptors, and other phenomena caused by the abortion.
*
* Therefore you should not use these as a general replacement for TEST_CHECK.
* Use it with some caution, especially if your test causes some other side
* effects to the outside world (e.g. communicating with some server, inserting

* failure, without the need to manually output the iteration-specific data in
* every single TEST_CHECK inside the loop body.
*
* TEST_CASE allows to specify only single string as the name of the case,
* TEST_CASE_ provides all the power of printf-like string formatting.
*

* this header. The expansion of the macro is then used as a body of helper
* function called just before executing every single (TEST_INIT) or just after
* it ends (TEST_FINI).
*
* Examples of various ways how to use the macro TEST_INIT:
*
* #define TEST_INIT my_init_func();
* #define TEST_INIT my_init_func() // Works even without the semicolon
* #define TEST_INIT setlocale(LC_ALL, NULL);
* #define TEST_INIT { setlocale(LC_ALL, NULL); my_init_func(); }
*
* TEST_FINI is to be used in the same way.
