/**
|

* SECTION:testing
|
||
* @title: Testing
|
||
* @short_description: a test framework
|
||
*
|
||
* GLib provides a framework for writing and maintaining unit tests
|
||
* in parallel to the code they are testing. The API is designed according
|
||
* to established concepts found in the other test frameworks (JUnit, NUnit,
|
||
* RUnit), which in turn is based on smalltalk unit testing concepts.
|
||
*
|
||
* - Test case: Tests (test methods) are grouped together with their
|
||
* fixture into test cases.
|
||
*
|
||
* - Fixture: A test fixture consists of fixture data and setup and
|
||
* teardown methods to establish the environment for the test
|
||
* functions. We use fresh fixtures, i.e. fixtures are newly set
|
||
* up and torn down around each test invocation to avoid dependencies
|
||
* between tests.
|
||
*
|
||
* - Test suite: Test cases can be grouped into test suites, to allow
|
||
* subsets of the available tests to be run. Test suites can be
|
||
* grouped into other test suites as well.
|
||
*
|
||
* The API is designed to handle creation and registration of test suites
|
||
* and test cases implicitly. A simple call like
|
||
* |[<!-- language="C" -->
|
||
* g_test_add_func ("/misc/assertions", test_assertions);
|
||
* ]|
|
||
* creates a test suite called "misc" with a single test case named
|
||
* "assertions", which consists of running the test_assertions function.
|
||
*
|
||
* In addition to the traditional g_assert_true(), the test framework provides
|
||
* an extended set of assertions for comparisons: g_assert_cmpfloat(),
|
||
* g_assert_cmpfloat_with_epsilon(), g_assert_cmpint(), g_assert_cmpuint(),
|
||
* g_assert_cmphex(), g_assert_cmpstr(), g_assert_cmpmem() and
|
||
* g_assert_cmpvariant(). The
|
||
* advantage of these variants over plain g_assert_true() is that the assertion
|
||
* messages can be more elaborate, and include the values of the compared
|
||
* entities.
|
||
*
|
||
* Note that g_assert() should not be used in unit tests, since it is a no-op
|
||
* when compiling with `G_DISABLE_ASSERT`. Use g_assert() in production code,
|
||
* and g_assert_true() in unit tests.
|
||
*
|
||
* A full example of creating a test suite with two tests using fixtures:
|
||
* |[<!-- language="C" -->
|
||
* #include <glib.h>
|
||
* #include <locale.h>
|
||
*
|
||
* typedef struct {
|
||
* MyObject *obj;
|
||
* OtherObject *helper;
|
||
* } MyObjectFixture;
|
||
*
|
||
* static void
|
||
* my_object_fixture_set_up (MyObjectFixture *fixture,
|
||
* gconstpointer user_data)
|
||
* {
|
||
* fixture->obj = my_object_new ();
|
||
* my_object_set_prop1 (fixture->obj, "some-value");
|
||
* my_object_do_some_complex_setup (fixture->obj, user_data);
|
||
*
|
||
* fixture->helper = other_object_new ();
|
||
* }
|
||
*
|
||
* static void
|
||
* my_object_fixture_tear_down (MyObjectFixture *fixture,
|
||
* gconstpointer user_data)
|
||
* {
|
||
* g_clear_object (&fixture->helper);
|
||
* g_clear_object (&fixture->obj);
|
||
* }
|
||
*
|
||
* static void
|
||
* test_my_object_test1 (MyObjectFixture *fixture,
|
||
* gconstpointer user_data)
|
||
* {
|
||
* g_assert_cmpstr (my_object_get_property (fixture->obj), ==, "initial-value");
|
||
* }
|
||
*
|
||
* static void
|
||
* test_my_object_test2 (MyObjectFixture *fixture,
|
||
* gconstpointer user_data)
|
||
* {
|
||
* my_object_do_some_work_using_helper (fixture->obj, fixture->helper);
|
||
* g_assert_cmpstr (my_object_get_property (fixture->obj), ==, "updated-value");
|
||
* }
|
||
*
|
||
* int
|
||
* main (int argc, char *argv[])
|
||
* {
|
||
* setlocale (LC_ALL, "");
|
||
*
|
||
* g_test_init (&argc, &argv, NULL);
|
||
*
|
||
* // Define the tests.
|
||
* g_test_add ("/my-object/test1", MyObjectFixture, "some-user-data",
|
||
* my_object_fixture_set_up, test_my_object_test1,
|
||
* my_object_fixture_tear_down);
|
||
* g_test_add ("/my-object/test2", MyObjectFixture, "some-user-data",
|
||
* my_object_fixture_set_up, test_my_object_test2,
|
||
* my_object_fixture_tear_down);
|
||
*
|
||
* return g_test_run ();
|
||
* }
|
||
* ]|
|
||
*
|
||
* ### Integrating GTest in your project
|
||
*
|
||
* If you are using the [Meson](http://mesonbuild.com) build system, you will
|
||
* typically use the provided `test()` primitive to call the test binaries,
|
||
* e.g.:
|
||
*
|
||
* |[<!-- language="plain" -->
|
||
* test(
|
||
* 'foo',
|
||
* executable('foo', 'foo.c', dependencies: deps),
|
||
* env: [
|
||
* 'G_TEST_SRCDIR=@0@'.format(meson.current_source_dir()),
|
||
* 'G_TEST_BUILDDIR=@0@'.format(meson.current_build_dir()),
|
||
* ],
|
||
* )
|
||
*
|
||
* test(
|
||
* 'bar',
|
||
* executable('bar', 'bar.c', dependencies: deps),
|
||
* env: [
|
||
* 'G_TEST_SRCDIR=@0@'.format(meson.current_source_dir()),
|
||
* 'G_TEST_BUILDDIR=@0@'.format(meson.current_build_dir()),
|
||
* ],
|
||
* )
|
||
* ]|
|
||
*
|
||
* If you are using Autotools, you're strongly encouraged to use the Automake
|
||
* [TAP](https://testanything.org/) harness; GLib provides template files for
|
||
* easily integrating with it:
|
||
*
|
||
* - [glib-tap.mk](https://gitlab.gnome.org/GNOME/glib/blob/glib-2-58/glib-tap.mk)
|
||
* - [tap-test](https://gitlab.gnome.org/GNOME/glib/blob/glib-2-58/tap-test)
|
||
* - [tap-driver.sh](https://gitlab.gnome.org/GNOME/glib/blob/glib-2-58/tap-driver.sh)
|
||
*
|
||
* You can copy these files in your own project's root directory, and then
|
||
* set up your `Makefile.am` file to reference them, for instance:
|
||
*
|
||
* |[<!-- language="plain" -->
|
||
* include $(top_srcdir)/glib-tap.mk
|
||
*
|
||
* # test binaries
|
||
* test_programs = \
|
||
* foo \
|
||
* bar
|
||
*
|
||
* # data distributed in the tarball
|
||
* dist_test_data = \
|
||
* foo.data.txt \
|
||
* bar.data.txt
|
||
*
|
||
* # data not distributed in the tarball
|
||
* test_data = \
|
||
* blah.data.txt
|
||
* ]|
|
||
*
|
||
* Make sure to distribute the TAP files, using something like the following
|
||
* in your top-level `Makefile.am`:
|
||
*
|
||
* |[<!-- language="plain" -->
|
||
* EXTRA_DIST += \
|
||
* tap-driver.sh \
|
||
* tap-test
|
||
* ]|
|
||
*
|
||
* `glib-tap.mk` will be distributed implicitly due to being included in a
|
||
* `Makefile.am`. All three files should be added to version control.
|
||
*
|
||
* If you don't have access to the Autotools TAP harness, you can use the
|
||
* [gtester][gtester] and [gtester-report][gtester-report] tools, and use
|
||
* the [glib.mk](https://gitlab.gnome.org/GNOME/glib/blob/glib-2-58/glib.mk)
|
||
* Automake template provided by GLib. Note, however, that since GLib 2.62,
|
||
* [gtester][gtester] and [gtester-report][gtester-report] have been deprecated
|
||
* in favour of using TAP. The `--tap` argument to tests is enabled by default
|
||
* as of GLib 2.62.

* test random number generator, the name for g_get_prgname()
|
||
* and parsing test related command line args.
|
||
*
|
||
* So far, the following arguments are understood:
|
||
*
|
||
* - `-l`: List test cases available in a test executable.
|
||
* - `--seed=SEED`: Provide a random seed to reproduce test
|
||
* runs using random numbers.
|
||
* - `--verbose`: Run tests verbosely.
|
||
* - `-q`, `--quiet`: Run tests quietly.
|
||
* - `-p PATH`: Execute all tests matching the given path.
|
||
* - `-s PATH`: Skip all tests matching the given path.
|
||
* This can also be used to force a test to run that would otherwise
|
||
* be skipped (ie, a test whose name contains "/subprocess").
|
||
* - `-m {perf|slow|thorough|quick|undefined|no-undefined}`: Execute tests according to these test modes:
|
||
*
|
||
* `perf`: Performance tests, may take long and report results (off by default).
|
||
*
|
||
* `slow`, `thorough`: Slow and thorough tests, may take quite long and maximize coverage
|
||
* (off by default).
|
||
*
|
||
* `quick`: Quick tests, should run really quickly and give good coverage (the default).
|
||
*
|
||
* `undefined`: Tests for undefined behaviour, may provoke programming errors
|
||
* under g_test_trap_subprocess() or g_test_expect_message() to check
|
||
* that appropriate assertions or warnings are given (the default).
|
||
*
|
||
* `no-undefined`: Avoid tests for undefined behaviour
|
||
*
|
||
* - `--debug-log`: Debug test logging output.
|
||
*
|
||
* Options which can be passed to @... are:
|
||
*
|
||
* - `"no_g_set_prgname"`: Causes g_test_init() to not call g_set_prgname().
|
||
* - %G_TEST_OPTION_ISOLATE_DIRS: Creates a unique temporary directory for each
|
||
* unit test and uses g_set_user_dirs() to set XDG directories to point into
|
||
* that temporary directory for the duration of the unit test. See the
|
||
* documentation for %G_TEST_OPTION_ISOLATE_DIRS.
|
||
*
|
||
* Since 2.58, if tests are compiled with `G_DISABLE_ASSERT` defined,
|
||
* g_test_init() will print an error and exit. This is to prevent no-op tests

|

|
||
* In general, the tests and sub-suites within each suite are run in
|
||
* the order in which they are defined. However, note that prior to
|
||
* GLib 2.36, there was a bug in the `g_test_add_*`
|
||
* functions which caused them to create multiple suites with the same
|
||
* name, meaning that if you created tests "/foo/simple",
|
||
* "/bar/simple", and "/foo/using-bar" in that order, they would get
|
||
* run in that order (since g_test_run() would run the first "/foo"
|
||
* suite, then the "/bar" suite, then the second "/foo" suite). As of
|
||
* 2.36, this bug is fixed, and adding the tests in that order would
|
||
* result in a running order of "/foo/simple", "/foo/using-bar",
|
||
* "/bar/simple". If this new ordering is sub-optimal (because it puts
|
||
* more-complicated tests before simpler ones, making it harder to
|
||
* figure out exactly what has failed), you can fix it by changing the
|
||
* test paths to group tests by suite in a way that will result in the
|
||
* desired running order. Eg, "/simple/foo", "/simple/bar",
|
||
* "/complex/foo-using-bar".
|
||
*
|
||
* However, you should never make the actual result of a test depend
|
||
* on the order that tests are run in. If you need to ensure that some
