63 * GLib provides a framework for writing and maintaining unit tests
64 * in parallel to the code they are testing. The API is designed according
65 * to established concepts found in the other test frameworks (JUnit, NUnit,
66 * RUnit), which in turn is based on smalltalk unit testing concepts.
70 * <term>Test case</term>
71 * <listitem>Tests (test methods) are grouped together with their
72 * fixture into test cases.</listitem>
75 * <term>Fixture</term>
76 * <listitem>A test fixture consists of fixture data and setup and
77 * teardown methods to establish the environment for the test
78 * functions. We use fresh fixtures, i.e. fixtures are newly set
79 * up and torn down around each test invocation to avoid dependencies
80 * between tests.</listitem>
83 * <term>Test suite</term>
84 * <listitem>Test cases can be grouped into test suites, to allow
85 * subsets of the available tests to be run. Test suites can be
86 * grouped into other test suites as well.</listitem>
89 * The API is designed to handle creation and registration of test suites
90 * and test cases implicitly. A simple call like
92 * g_test_add_func ("/misc/assertions", test_assertions);
94 * creates a test suite called "misc" with a single test case named
95 * "assertions", which consists of running the test_assertions function.
97 * In addition to the traditional g_assert(), the test framework provides
98 * an extended set of assertions for string and numerical comparisons:
99 * g_assert_cmpfloat(), g_assert_cmpint(), g_assert_cmpuint(),
100 * g_assert_cmphex(), g_assert_cmpstr(). The advantage of these variants
101 * over plain g_assert() is that the assertion messages can be more
102 * elaborate, and include the values of the compared entities.
104 * GLib ships with two utilities called gtester and gtester-report to
105 * facilitate running tests and producing nicely formatted test reports.
109 * g_test_initialized:
111 * Returns %TRUE if g_test_init() has been called.
113 * Returns: %TRUE if g_test_init() has been called.
121 * Returns %TRUE if tests are run in quick mode.
122 * Exactly one of g_test_quick() and g_test_slow() is active in any run;
123 * there is no "medium speed".
125 * Returns: %TRUE if in quick mode
131 * Returns %TRUE if tests are run in slow mode.
132 * Exactly one of g_test_quick() and g_test_slow() is active in any run;
133 * there is no "medium speed".
135 * Returns: the opposite of g_test_quick()
141 * Returns %TRUE if tests are run in thorough mode, equivalent to
144 * Returns: the same thing as g_test_slow()
150 * Returns %TRUE if tests are run in performance mode.
152 * Returns: %TRUE if in performance mode
158 * Returns %TRUE if tests may provoke assertions and other formally-undefined
159 * behaviour under g_test_trap_fork(), to verify that appropriate warnings
160 * are given. It can be useful to turn this off if running tests under
163 * Returns: %TRUE if tests may provoke programming errors
169 * Returns %TRUE if tests are run in verbose mode.
170 * The default is neither g_test_verbose() nor g_test_quiet().
172 * Returns: %TRUE if in verbose mode
178 * Returns %TRUE if tests are run in quiet mode.
179 * The default is neither g_test_verbose() nor g_test_quiet().
181 * Returns: %TRUE if in quiet mode
185 * g_test_queue_unref:
186 * @gobject: the object to unref
188 * Enqueue an object to be released with g_object_unref() during
189 * the next teardown phase. This is equivalent to calling
190 * g_test_queue_destroy() with a destroy callback of g_object_unref().
197 * @G_TEST_TRAP_SILENCE_STDOUT: Redirect stdout of the test child to
198 * <filename>/dev/null</filename> so it cannot be observed on the
199 * console during test runs. The actual output is still captured
200 * though to allow later tests with g_test_trap_assert_stdout().
201 * @G_TEST_TRAP_SILENCE_STDERR: Redirect stderr of the test child to
202 * <filename>/dev/null</filename> so it cannot be observed on the
203 * console during test runs. The actual output is still captured
204 * though to allow later tests with g_test_trap_assert_stderr().
205 * @G_TEST_TRAP_INHERIT_STDIN: If this flag is given, stdin of the
206 * forked child process is shared with stdin of its parent process.
207 * It is redirected to <filename>/dev/null</filename> otherwise.
209 * Test traps are guards around forked tests.
210 * These flags determine what traps to set.
214 * g_test_trap_assert_passed:
216 * Assert that the last forked test passed.
217 * See g_test_trap_fork().
223 * g_test_trap_assert_failed:
225 * Assert that the last forked test failed.
226 * See g_test_trap_fork().
228 * This is sometimes used to test situations that are formally considered to
229 * be undefined behaviour, like inputs that fail a g_return_if_fail()
230 * check. In these situations you should skip the entire test, including the
231 * call to g_test_trap_fork(), unless g_test_undefined() returns %TRUE
232 * to indicate that undefined behaviour may be tested.
238 * g_test_trap_assert_stdout:
239 * @soutpattern: a glob-style
240 * <link linkend="glib-Glob-style-pattern-matching">pattern</link>
242 * Assert that the stdout output of the last forked test matches
243 * @soutpattern. See g_test_trap_fork().
249 * g_test_trap_assert_stdout_unmatched:
250 * @soutpattern: a glob-style
251 * <link linkend="glib-Glob-style-pattern-matching">pattern</link>
253 * Assert that the stdout output of the last forked test
254 * does not match @soutpattern. See g_test_trap_fork().
260 * g_test_trap_assert_stderr:
261 * @serrpattern: a glob-style
262 * <link linkend="glib-Glob-style-pattern-matching">pattern</link>
264 * Assert that the stderr output of the last forked test
265 * matches @serrpattern. See g_test_trap_fork().
267 * This is sometimes used to test situations that are formally considered to
268 * be undefined behaviour, like inputs that fail a g_return_if_fail()
269 * check. In these situations you should skip the entire test, including the
270 * call to g_test_trap_fork(), unless g_test_undefined() returns %TRUE
271 * to indicate that undefined behaviour may be tested.
277 * g_test_trap_assert_stderr_unmatched:
278 * @serrpattern: a glob-style
279 * <link linkend="glib-Glob-style-pattern-matching">pattern</link>
281 * Assert that the stderr output of the last forked test
282 * does not match @serrpattern. See g_test_trap_fork().
290 * Get a reproducible random bit (0 or 1), see g_test_rand_int()
291 * for details on test case random numbers.
298 * @expr: the expression to check
300 * Debugging macro to terminate the application if the assertion
301 * fails. If the assertion fails (i.e. the expression is not true),
302 * an error message is logged and the application is terminated.
304 * The macro can be turned off in final releases of code by defining
305 * <envar>G_DISABLE_ASSERT</envar> when compiling the application.
309 * g_assert_not_reached:
311 * Debugging macro to terminate the application if it is ever
312 * reached. If it is reached, an error message is logged and the
313 * application is terminated.
315 * The macro can be turned off in final releases of code by defining
316 * <envar>G_DISABLE_ASSERT</envar> when compiling the application.
321 * @s1: a string (may be %NULL)
322 * @cmp: The comparison operator to use.
323 * One of ==, !=, <, >, <=, >=.
324 * @s2: another string (may be %NULL)
326 * Debugging macro to terminate the application with a warning
327 * message if a string comparison fails. The strings are compared
330 * The effect of <literal>g_assert_cmpstr (s1, op, s2)</literal> is
331 * the same as <literal>g_assert (g_strcmp0 (s1, s2) op 0)</literal>.
332 * The advantage of this macro is that it can produce a message that
333 * includes the actual values of @s1 and @s2.
336 * g_assert_cmpstr (mystring, ==, "fubar");
345 * @cmp: The comparison operator to use.
346 * One of ==, !=, <, >, <=, >=.
347 * @n2: another integer
349 * Debugging macro to terminate the application with a warning
350 * message if an integer comparison fails.
352 * The effect of <literal>g_assert_cmpint (n1, op, n2)</literal> is
353 * the same as <literal>g_assert (n1 op n2)</literal>. The advantage
354 * of this macro is that it can produce a message that includes the
355 * actual values of @n1 and @n2.
362 * @n1: an unsigned integer
363 * @cmp: The comparison operator to use.
364 * One of ==, !=, <, >, <=, >=.
365 * @n2: another unsigned integer
367 * Debugging macro to terminate the application with a warning
368 * message if an unsigned integer comparison fails.
370 * The effect of <literal>g_assert_cmpuint (n1, op, n2)</literal> is
371 * the same as <literal>g_assert (n1 op n2)</literal>. The advantage
372 * of this macro is that it can produce a message that includes the
373 * actual values of @n1 and @n2.
380 * @n1: an unsigned integer
381 * @cmp: The comparison operator to use.
382 * One of ==, !=, <, >, <=, >=.
383 * @n2: another unsigned integer
385 * Debugging macro to terminate the application with a warning
386 * message if an unsigned integer comparison fails.
388 * This is a variant of g_assert_cmpuint() that displays the numbers
389 * in hexadecimal notation in the message.
396 * @n1: an floating point number
397 * @cmp: The comparison operator to use.
398 * One of ==, !=, <, >, <=, >=.
399 * @n2: another floating point number
401 * Debugging macro to terminate the application with a warning
402 * message if a floating point number comparison fails.
404 * The effect of <literal>g_assert_cmpfloat (n1, op, n2)</literal> is
405 * the same as <literal>g_assert (n1 op n2)</literal>. The advantage
406 * of this macro is that it can produce a message that includes the
407 * actual values of @n1 and @n2.
414 * @err: a #GError, possibly %NULL
416 * Debugging macro to terminate the application with a warning
417 * message if a method has returned a #GError.
419 * The effect of <literal>g_assert_no_error (err)</literal> is
420 * the same as <literal>g_assert (err == NULL)</literal>. The advantage
421 * of this macro is that it can produce a message that includes
422 * the error message and code.
429 * @err: a #GError, possibly %NULL
430 * @dom: the expected error domain (a #GQuark)
431 * @c: the expected error code
433 * Debugging macro to terminate the application with a warning
434 * message if a method has not returned the correct #GError.
436 * The effect of <literal>g_assert_error (err, dom, c)</literal> is
437 * the same as <literal>g_assert (err != NULL && err->domain
438 * == dom && err->code == c)</literal>. The advantage of this
439 * macro is that it can produce a message that includes the incorrect
440 * error message and code.
442 * This can only be used to test for a specific error. If you want to
443 * test that @err is set, but don't care what it's set to, just use
444 * <literal>g_assert (err != NULL)</literal>
452 * An opaque structure representing a test case.
458 * An opaque structure representing a test suite.
