67 * @short_description: a test framework
68 * @see_also: <link linkend="gtester">gtester</link>,
69 * <link linkend="gtester-report">gtester-report</link>
71 * GLib provides a framework for writing and maintaining unit tests
72 * in parallel to the code they are testing. The API is designed according
73 * to established concepts found in the other test frameworks (JUnit, NUnit,
74 * RUnit), which in turn is based on smalltalk unit testing concepts.
78 * <term>Test case</term>
79 * <listitem>Tests (test methods) are grouped together with their
80 * fixture into test cases.</listitem>
83 * <term>Fixture</term>
84 * <listitem>A test fixture consists of fixture data and setup and
85 * teardown methods to establish the environment for the test
86 * functions. We use fresh fixtures, i.e. fixtures are newly set
87 * up and torn down around each test invocation to avoid dependencies
88 * between tests.</listitem>
91 * <term>Test suite</term>
92 * <listitem>Test cases can be grouped into test suites, to allow
93 * subsets of the available tests to be run. Test suites can be
94 * grouped into other test suites as well.</listitem>
97 * The API is designed to handle creation and registration of test suites
98 * and test cases implicitly. A simple call like
100 * g_test_add_func ("/misc/assertions", test_assertions);
102 * creates a test suite called "misc" with a single test case named
103 * "assertions", which consists of running the test_assertions function.
105 * In addition to the traditional g_assert(), the test framework provides
106 * an extended set of assertions for string and numerical comparisons:
107 * g_assert_cmpfloat(), g_assert_cmpint(), g_assert_cmpuint(),
108 * g_assert_cmphex(), g_assert_cmpstr(). The advantage of these variants
109 * over plain g_assert() is that the assertion messages can be more
110 * elaborate, and include the values of the compared entities.
112 * GLib ships with two utilities called gtester and gtester-report to
113 * facilitate running tests and producing nicely formatted test reports.
117 * g_test_initialized:
119 * Returns %TRUE if g_test_init() has been called.
121 * Returns: %TRUE if g_test_init() has been called.
129 * Returns %TRUE if tests are run in quick mode.
130 * Exactly one of g_test_quick() and g_test_slow() is active in any run;
131 * there is no "medium speed".
133 * Returns: %TRUE if in quick mode
139 * Returns %TRUE if tests are run in slow mode.
140 * Exactly one of g_test_quick() and g_test_slow() is active in any run;
141 * there is no "medium speed".
143 * Returns: the opposite of g_test_quick()
149 * Returns %TRUE if tests are run in thorough mode, equivalent to
152 * Returns: the same thing as g_test_slow()
158 * Returns %TRUE if tests are run in performance mode.
160 * Returns: %TRUE if in performance mode
166 * Returns %TRUE if tests may provoke assertions and other formally-undefined
167 * behaviour, to verify that appropriate warnings are given. It might, in some
168 * cases, be useful to turn this off if running tests under valgrind.
170 * Returns: %TRUE if tests may provoke programming errors
176 * Returns %TRUE if tests are run in verbose mode.
177 * The default is neither g_test_verbose() nor g_test_quiet().
179 * Returns: %TRUE if in verbose mode
185 * Returns %TRUE if tests are run in quiet mode.
186 * The default is neither g_test_verbose() nor g_test_quiet().
188 * Returns: %TRUE if in quiet mode
192 * g_test_queue_unref:
193 * @gobject: the object to unref
195 * Enqueue an object to be released with g_object_unref() during
196 * the next teardown phase. This is equivalent to calling
197 * g_test_queue_destroy() with a destroy callback of g_object_unref().
204 * @G_TEST_TRAP_SILENCE_STDOUT: Redirect stdout of the test child to
205 * <filename>/dev/null</filename> so it cannot be observed on the
206 * console during test runs. The actual output is still captured
207 * though to allow later tests with g_test_trap_assert_stdout().
208 * @G_TEST_TRAP_SILENCE_STDERR: Redirect stderr of the test child to
209 * <filename>/dev/null</filename> so it cannot be observed on the
210 * console during test runs. The actual output is still captured
211 * though to allow later tests with g_test_trap_assert_stderr().
212 * @G_TEST_TRAP_INHERIT_STDIN: If this flag is given, stdin of the
213 * child process is shared with stdin of its parent process.
214 * It is redirected to <filename>/dev/null</filename> otherwise.
216 * Test traps are guards around forked tests.
217 * These flags determine what traps to set.
219 * Deprecated: #GTestTrapFlags is used only with g_test_trap_fork(),
220 * which is deprecated. g_test_trap_subprocess() uses
221 * #GTestTrapSubprocessFlags.
225 * GTestSubprocessFlags:
226 * @G_TEST_SUBPROCESS_INHERIT_STDIN: If this flag is given, the child
227 * process will inherit the parent's stdin. Otherwise, the child's
228 * stdin is redirected to <filename>/dev/null</filename>.
229 * @G_TEST_SUBPROCESS_INHERIT_STDOUT: If this flag is given, the child
230 * process will inherit the parent's stdout. Otherwise, the child's
231 * stdout will not be visible, but it will be captured to allow
232 * later tests with g_test_trap_assert_stdout().
233 * @G_TEST_SUBPROCESS_INHERIT_STDERR: If this flag is given, the child
234 * process will inherit the parent's stderr. Otherwise, the child's
235 * stderr will not be visible, but it will be captured to allow
236 * later tests with g_test_trap_assert_stderr().
238 * Flags to pass to g_test_trap_subprocess() to control input and output.
240 * Note that in contrast with g_test_trap_fork(), the default is to
241 * not show stdout and stderr.
245 * g_test_trap_assert_passed:
247 * Assert that the last test subprocess passed.
248 * See g_test_trap_subprocess().
254 * g_test_trap_assert_failed:
256 * Assert that the last test subprocess failed.
257 * See g_test_trap_subprocess().
259 * This is sometimes used to test situations that are formally considered to
260 * be undefined behaviour, like inputs that fail a g_return_if_fail()
261 * check. In these situations you should skip the entire test, including the
262 * call to g_test_trap_subprocess(), unless g_test_undefined() returns %TRUE
263 * to indicate that undefined behaviour may be tested.
269 * g_test_trap_assert_stdout:
270 * @soutpattern: a glob-style
271 * <link linkend="glib-Glob-style-pattern-matching">pattern</link>
273 * Assert that the stdout output of the last test subprocess matches
274 * @soutpattern. See g_test_trap_subprocess().
280 * g_test_trap_assert_stdout_unmatched:
281 * @soutpattern: a glob-style
282 * <link linkend="glib-Glob-style-pattern-matching">pattern</link>
284 * Assert that the stdout output of the last test subprocess
285 * does not match @soutpattern. See g_test_trap_subprocess().
291 * g_test_trap_assert_stderr:
292 * @serrpattern: a glob-style
293 * <link linkend="glib-Glob-style-pattern-matching">pattern</link>
295 * Assert that the stderr output of the last test subprocess
296 * matches @serrpattern. See g_test_trap_subprocess().
298 * This is sometimes used to test situations that are formally
299 * considered to be undefined behaviour, like code that hits a
300 * g_assert() or g_error(). In these situations you should skip the
301 * entire test, including the call to g_test_trap_subprocess(), unless
302 * g_test_undefined() returns %TRUE to indicate that undefined
303 * behaviour may be tested.
309 * g_test_trap_assert_stderr_unmatched:
310 * @serrpattern: a glob-style
311 * <link linkend="glib-Glob-style-pattern-matching">pattern</link>
313 * Assert that the stderr output of the last test subprocess
314 * does not match @serrpattern. See g_test_trap_subprocess().
322 * Get a reproducible random bit (0 or 1), see g_test_rand_int()
323 * for details on test case random numbers.
330 * @expr: the expression to check
332 * Debugging macro to terminate the application if the assertion
333 * fails. If the assertion fails (i.e. the expression is not true),
334 * an error message is logged and the application is terminated.
336 * The macro can be turned off in final releases of code by defining
337 * <envar>G_DISABLE_ASSERT</envar> when compiling the application.
341 * g_assert_not_reached:
343 * Debugging macro to terminate the application if it is ever
344 * reached. If it is reached, an error message is logged and the
345 * application is terminated.
347 * The macro can be turned off in final releases of code by defining
348 * <envar>G_DISABLE_ASSERT</envar> when compiling the application.
353 * @s1: a string (may be %NULL)
354 * @cmp: The comparison operator to use.
355 * One of ==, !=, <, >, <=, >=.
356 * @s2: another string (may be %NULL)
358 * Debugging macro to terminate the application with a warning
359 * message if a string comparison fails. The strings are compared
362 * The effect of <literal>g_assert_cmpstr (s1, op, s2)</literal> is
363 * the same as <literal>g_assert (g_strcmp0 (s1, s2) op 0)</literal>.
364 * The advantage of this macro is that it can produce a message that
365 * includes the actual values of @s1 and @s2.
368 * g_assert_cmpstr (mystring, ==, "fubar");
377 * @cmp: The comparison operator to use.
378 * One of ==, !=, <, >, <=, >=.
379 * @n2: another integer
381 * Debugging macro to terminate the application with a warning
382 * message if an integer comparison fails.
384 * The effect of <literal>g_assert_cmpint (n1, op, n2)</literal> is
385 * the same as <literal>g_assert (n1 op n2)</literal>. The advantage
386 * of this macro is that it can produce a message that includes the
387 * actual values of @n1 and @n2.
394 * @n1: an unsigned integer
395 * @cmp: The comparison operator to use.
396 * One of ==, !=, <, >, <=, >=.
397 * @n2: another unsigned integer
399 * Debugging macro to terminate the application with a warning
400 * message if an unsigned integer comparison fails.
402 * The effect of <literal>g_assert_cmpuint (n1, op, n2)</literal> is
403 * the same as <literal>g_assert (n1 op n2)</literal>. The advantage
404 * of this macro is that it can produce a message that includes the
405 * actual values of @n1 and @n2.
412 * @n1: an unsigned integer
413 * @cmp: The comparison operator to use.
414 * One of ==, !=, <, >, <=, >=.
415 * @n2: another unsigned integer
417 * Debugging macro to terminate the application with a warning
418 * message if an unsigned integer comparison fails.
420 * This is a variant of g_assert_cmpuint() that displays the numbers
421 * in hexadecimal notation in the message.
428 * @n1: an floating point number
429 * @cmp: The comparison operator to use.
430 * One of ==, !=, <, >, <=, >=.
431 * @n2: another floating point number
433 * Debugging macro to terminate the application with a warning
434 * message if a floating point number comparison fails.
436 * The effect of <literal>g_assert_cmpfloat (n1, op, n2)</literal> is
437 * the same as <literal>g_assert (n1 op n2)</literal>. The advantage
438 * of this macro is that it can produce a message that includes the
439 * actual values of @n1 and @n2.
446 * @err: a #GError, possibly %NULL
448 * Debugging macro to terminate the application with a warning
449 * message if a method has returned a #GError.
451 * The effect of <literal>g_assert_no_error (err)</literal> is
452 * the same as <literal>g_assert (err == NULL)</literal>. The advantage
453 * of this macro is that it can produce a message that includes
454 * the error message and code.
461 * @err: a #GError, possibly %NULL
462 * @dom: the expected error domain (a #GQuark)
463 * @c: the expected error code
465 * Debugging macro to terminate the application with a warning
466 * message if a method has not returned the correct #GError.
468 * The effect of <literal>g_assert_error (err, dom, c)</literal> is
469 * the same as <literal>g_assert (err != NULL && err->domain
470 * == dom && err->code == c)</literal>. The advantage of this
471 * macro is that it can produce a message that includes the incorrect
472 * error message and code.
474 * This can only be used to test for a specific error. If you want to
475 * test that @err is set, but don't care what it's set to, just use
476 * <literal>g_assert (err != NULL)</literal>
484 * An opaque structure representing a test case.
490 * An opaque structure representing a test suite.
494 /* Global variable for storing assertion messages; this is the counterpart to
495 * glibc's (private) __abort_msg variable, and allows developers and crash
496 * analysis systems like Apport and ABRT to fish out assertion messages from
497 * core dumps, instead of having to catch them on screen output.
