g_test_minimized_result ()

void                g_test_minimized_result             (double minimized_quantity,
                                                         const char *format,
                                                         ...);

Report the result of a performance or measurement test. The test should generally strive to minimize the reported quantities (smaller values are better than larger ones), this and minimized_quantity can determine sorting order for test result reports.

Since 2.16

g_test_maximized_result ()

void                g_test_maximized_result             (double maximized_quantity,
                                                         const char *format,
                                                         ...);

Report the result of a performance or measurement test. The test should generally strive to maximize the reported quantities (larger values are better than smaller ones), this and maximized_quantity can determine sorting order for test result reports.

g_test_init ()

void                g_test_init                         (int *argc,
                                                         char ***argv,
                                                         ...);

Initialize the GLib testing framework, e.g. by seeding the test random number generator, the name for g_get_prgname() and parsing test related command line args. So far, the following arguments are understood:

Since 2.16

g_test_quick()

g_test_run ()

int                 g_test_run                          (void);

Runs all tests under the toplevel suite which can be retrieved with g_test_get_root(). Similar to g_test_run_suite(), the test cases to be run are filtered according to test path arguments (-p testpath) as parsed by g_test_init(). g_test_run_suite() or g_test_run() may only be called once in a program.

Since 2.16

g_test_add_func ()

void                g_test_add_func                     (const char *testpath,
                                                         void (test_funcvoid) ());

Create a new test case, similar to g_test_create_case(). However the test is assumed to use no fixture, and test suites are automatically created on the fly and added to the root fixture, based on the slash seperated portions of testpath.

Since 2.16

g_test_add_data_func ()

void                g_test_add_data_func                (const char *testpath,
                                                         gconstpointer test_data,
                                                         void (test_funcgconstpointer) ());

Create a new test case, similar to g_test_create_case(). However the test is assumed to use no fixture, and test suites are automatically created on the fly and added to the root fixture, based on the slash seperated portions of testpath. The test_data argument will be passed as first argument to test_func.

Since 2.16

g_test_add()

#define             g_test_add(testpath, Fixture, tdata, fsetup, ftest, fteardown)

Hook up a new test case at testpath, similar to g_test_add_func(). A fixture data structure with setup and teardown function may be provided though, simmilar to g_test_create_case(). g_test_add() is implemented as a macro, so that the fsetup(), ftest() and fteardown() callbacks can expect a Fixture pointer as first argument in a type safe manner.

Since 2.16

g_test_message ()

void                g_test_message                      (const char *format,
                                                         ...);

Add a message to the test report.

Since 2.16

g_test_bug_base ()

void                g_test_bug_base                     (const char *uri_pattern);

Specify the base URI for bug reports. The base URI is used to construct bug report messages for g_test_message() when g_test_bug() is called. Calling this function outside of a test case sets the default base URI for all test cases. Calling it from within a test case changes the base URI for the scope of the test case only. Bug URIs are constructed by appending a bug specific URI portion to uri_pattern, or by replacing the special string 's' within uri_pattern if that is present.

Since 2.16

g_test_bug ()

void                g_test_bug                          (const char *bug_uri_snippet);

This function adds a message to test reports that associates a bug URI with a test case. Bug URIs are constructed from a base URI set with g_test_bug_base() and bug_uri_snippet.

Since 2.16

g_test_timer_start ()

void                g_test_timer_start                  (void);

Start a timing test. Call g_test_timer_elapsed() when the task is supposed to be done. Call this function again to restart the timer.

Since 2.16

g_test_timer_elapsed ()

double              g_test_timer_elapsed                (void);

Get the time since the last start of the timer with g_test_timer_start().

Since 2.16

g_test_timer_last ()

double              g_test_timer_last                   (void);

Report the last result of g_test_timer_elapsed().

Since 2.16

g_test_queue_free ()

void                g_test_queue_free                   (gpointer gfree_pointer);

Enqueue a pointer to be released with g_free() during the next teardown phase. This is equivalent to calling g_test_queue_destroy() with a destroy callback of g_free().

Since 2.16

g_test_queue_destroy ()

void                g_test_queue_destroy                (GDestroyNotify destroy_func,
                                                         gpointer destroy_data);

This function enqueus a callback @destroy_func() to be executed during the next test case teardown phase. This is most useful to auto destruct allocted test resources at the end of a test run. Resources are released in reverse queue order, that means enqueueing callback A before callback B will cause B() to be called before A() during teardown.

Since 2.16

g_test_queue_unref()

#define             g_test_queue_unref(gobject)

enum GTestTrapFlags

typedef enum {
  G_TEST_TRAP_SILENCE_STDOUT    = 1 << 7,
  G_TEST_TRAP_SILENCE_STDERR    = 1 << 8,
  G_TEST_TRAP_INHERIT_STDIN     = 1 << 9
} GTestTrapFlags;

g_test_trap_fork ()

gboolean            g_test_trap_fork                    (guint64 usec_timeout,
                                                         GTestTrapFlags test_trap_flags);

Fork the current test program to execute a test case that might not return or that might abort. The forked test case is aborted and considered failing if its run time exceeds usec_timeout. The forking behavior can be configured with the following flags: G_TEST_TRAP_SILENCE_STDOUT - redirect stdout of the test child to /dev/null so it cannot be observed on the console during test runs. The actual output is still captured though to allow later tests with g_test_trap_assert_stdout(). G_TEST_TRAP_SILENCE_STDERR - redirect stderr of the test child to /dev/null so it cannot be observed on the console during test runs. The actual output is still captured though to allow later tests with g_test_trap_assert_stderr(). G_TEST_TRAP_INHERIT_STDIN - if this flag is given, stdin of the forked child process is shared with stdin of its parent process. It is redirected to /dev/null otherwise.

In the following example, the test code forks, the forked child process produces some sample output and exits successfully. The forking parent process then asserts successfull child program termination and validates child program outputs.

  static void
  test_fork_patterns (void)
  {
    if (g_test_trap_fork (0, G_TEST_TRAP_SILENCE_STDOUT | G_TEST_TRAP_SILENCE_STDERR))
      {
        g_print ("some stdout text: somagic17\n");
        g_printerr ("some stderr text: semagic43\n");
        exit (0); /* successful test run */
      }
    g_test_trap_assert_passed();
    g_test_trap_assert_stdout ("*somagic17*");
    g_test_trap_assert_stderr ("*semagic43*");
  }

This function is implemented only on Unix platforms.

g_test_rand_int ()

gint32              g_test_rand_int                     (void);

Get a reproducable random integer number. The random numbers generate by the g_test_rand_*() family of functions change with every new test program start, unless the --seed option is given when starting test programs. For individual test cases however, the random number generator is reseeded, to avoid dependencies between tests and to make --seed effective for all test cases.

Since 2.16
