* g_test_init:
* @argc: Address of the @argc parameter of the main() function.
* Changed if any arguments were handled.
* @argv: Address of the @argv parameter of main().
* Any parameters understood by g_test_init() stripped before return.
* @...: %NULL-terminated list of special options, documented below.
*
* 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.
*
* This should be called before calling any other `g_test_*()` functions.
*
* 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
* from being executed, as g_assert() is commonly (erroneously) used in unit
* tests, and is a no-op when compiled with `G_DISABLE_ASSERT`. Ensure your
* tests are compiled without `G_DISABLE_ASSERT` defined.

* In general, the tests and sub-suites within each suite are run in

* functions which caused them to create multiple suites with the same

* "/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
* particular code runs before or after a given test case, use
* g_test_add(), which lets you specify setup and teardown functions.

*
* When this test is executed, a fixture structure of size @data_size
* will be automatically allocated and filled with zeros. Then @data_setup is
* called to initialize the fixture. After fixture setup, the actual test
* function @data_test is called. Once the test run completes, the
* fixture structure is torn down by calling @data_teardown and
* after that the memory is automatically released by the test framework.
*
* Splitting up a test run into fixture setup, test function and
* fixture teardown is most useful if the same fixture type is used for
* multiple tests. In this cases, g_test_create_case() will be
* called with the same type of fixture (the @data_size argument), but varying
* @test_name and @data_test arguments.
