27 * OVS tests directory contains many small test programs. One down side
28 * of building them as individual programs is that they all have to be
29 * linked whenever a library function is modified.
31 * ovstest is an attempt to improve the overall build time by linking
32 * all test programs into a single program, ovs-test. Regardless of
33 * the number of test programs, linking will be done only once to produce
36 * With ovstest, each test programs now becomes a sub program of ovstest.
37 * For example, 'mytest' program, can now be invoked as 'ovstest mytest'.
39 * 'ovstest --help' will list all test programs can be invoked.
41 * The 'Usage' section below documents how to add a new sub program
42 * to ovstest using OVSTEST_REIGSTER macros.
45 typedef void (*ovstest_func)(int argc, char *argv[]);
47 void ovstest_register(const char *test_name, ovs_cmdl_handler f);
52 * For each sub test program, its 'main' program should be named as
53 * '<test_name>_main()'.
55 * The 'main' programs should be registered with ovstest as a sub program.
56 * OVSTEST_REGISTER(name, function)
58 * 'name' will be name of the test program. It is expected as argv[1] when
59 * invoking with ovstest.
61 * 'function' is the 'main' program mentioned above.
66 * Suppose the test program is called my-test.c
70 * my_test_main(int argc, char *argv[])
75 * OVSTEST_REGISTER("my-test", my_test_main);
