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