20 * Simple unit tests should implement register_tests().
21 * To register tests, call ADD_TEST or ADD_ALL_TESTS:
23 * void register_tests(void)
26 * ADD_ALL_TESTS(test_bar, num_test_bar);
29 * Tests that need to perform custom setup or read command-line arguments should
30 * implement test_main():
32 * int test_main(int argc, char *argv[])
39 * ADD_ALL_TESTS(test_bar, num_test_bar);
40 * // Add more tests ...
42 * ret = run_tests(argv[0]);
44 * // Custom teardown ...
50 /* Adds a simple test case. */
51 # define ADD_TEST(test_function) add_test(#test_function, test_function)
54 * Simple parameterized tests. Calls test_function(idx) for each 0 <= idx < num.
56 # define ADD_ALL_TESTS(test_function, num) \
57 add_all_tests(#test_function, test_function, num, 1)
59 * A variant of the same without TAP output.
61 # define ADD_ALL_TESTS_NOSUBTEST(test_function, num) \
62 add_all_tests(#test_function, test_function, num, 0)
65 * Test cases that share common setup should use the helper
66 * SETUP_TEST_FIXTURE and EXECUTE_TEST macros for test case functions.
68 * SETUP_TEST_FIXTURE will call set_up() to create a new TEST_FIXTURE_TYPE
69 * object called "fixture". It will also allocate the "result" variable used
70 * by EXECUTE_TEST. set_up() should take a const char* specifying the test
71 * case name and return a TEST_FIXTURE_TYPE by value.
73 * EXECUTE_TEST will pass fixture to execute_func() by value, call
74 * tear_down(), and return the result of execute_func(). execute_func() should
75 * take a TEST_FIXTURE_TYPE by value and return 1 on success and 0 on
78 * Unit tests can define their own SETUP_TEST_FIXTURE and EXECUTE_TEST
81 * #define SETUP_FOOBAR_TEST_FIXTURE()\
82 * SETUP_TEST_FIXTURE(FOOBAR_TEST_FIXTURE, set_up_foobar)
84 * #define EXECUTE_FOOBAR_TEST()\
85 * EXECUTE_TEST(execute_foobar, tear_down_foobar)
87 * Then test case functions can take the form:
89 * static int test_foobar_feature()
91 * SETUP_FOOBAR_TEST_FIXTURE();
92 * [...set individual members of fixture...]
93 * EXECUTE_FOOBAR_TEST();
96 # define SETUP_TEST_FIXTURE(TEST_FIXTURE_TYPE, set_up)\
97 TEST_FIXTURE_TYPE fixture = set_up(TEST_CASE_NAME); \

101 result = execute_func(fixture);\
105 /* Shorthand if tear_down does nothing. */
106 # define EXECUTE_TEST_NO_TEARDOWN(execute_func)\
107 result = execute_func(fixture);\
111 * TEST_CASE_NAME is defined as the name of the test case function where
112 * possible; otherwise we get by with the file name and line number.
