/* Overview
* ========
*
* OVS tests directory contains many small test programs. One down side
* of building them as individual programs is that they all have to be
* linked whenever a library function is modified.
*
* ovstest is an attempt to improve the overall build time by linking
* all test programs into a single program, ovs-test. Regardless of
* the number of test programs, linking will be done only once to produce
* ovstest.
*
* With ovstest, each test programs now becomes a sub program of ovstest.
* For example, 'mytest' program, can now be invoked as 'ovstest mytest'.
*
* 'ovstest --help' will list all test programs can be invoked.
*
* The 'Usage' section below documents how to add a new sub program
* to ovstest using OVSTEST_REIGSTER macros.
*/
typedef void (*ovstest_func)(int argc, char *argv[]);
void ovstest_register(const char *test_name, ovs_cmdl_handler f);
/* Usage
* =====
*
* For each sub test program, its 'main' program should be named as
* '<test_name>_main()'.
*
* The 'main' programs should be registered with ovstest as a sub program.
* OVSTEST_REGISTER(name, function)
*
* 'name' will be name of the test program. It is expected as argv[1] when
* invoking with ovstest.
*
* 'function' is the 'main' program mentioned above.
*
* Example:
* ----------
*
* Suppose the test program is called my-test.c
* ...
*
* static void
* my_test_main(int argc, char *argv[])
* {
* ....
* }
*
* OVSTEST_REGISTER("my-test", my_test_main);
