+ * GLib 2.36, there was a bug in the <literal>g_test_add_*</literal>
+ * 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

+ * g_test_build_filename:
+ * @file_type: the type of file (built vs. distributed)
+ * @first_path: the first segment of the pathname
+ * @...: %NULL-terminated additional path segments
+ *
+ * Creates the pathname to a data file that is required for a test.
+ *
+ * This function is conceptually similar to g_build_filename() except
+ * that the first argument has been replaced with a #GTestFileType
+ * argument.
+ *
+ * The data file should either have been distributed with the module
+ * containing the test (%G_TEST_DIST) or built as part of the build
+ * system of that module (%G_TEST_BUILT).
+ *
+ * In order for this function to work in srcdir != builddir situations,
+ * the G_TEST_SRCDIR and G_TEST_BUILDDIR environment variables need to
+ * have been defined. As of 2.38, this is done by the glib.mk
+ * included in GLib. Please ensure that your copy is up to date before
+ * using this function.
+ *
+ * In case neither variable is set, this function will fall back to
+ * using the dirname portion of argv[0], possibly removing ".libs".
+ * This allows for casual running of tests directly from the commandline
+ * in the srcdir == builddir case and should also support running of
+ * installed tests, assuming the data files have been installed in the
+ * same relative path as the test binary.
+ *
+ * Returns: the path of the file, to be freed using g_free()
+ *
+ * Since: 2.38

+/**
+ * GTestFileType:
+ * @G_TEST_DIST: a file that was included in the distribution tarball
+ * @G_TEST_BUILT: a file that was built on the compiling machine
+ *
+ * The type of file to return the filename for, when used with
+ * g_test_build_filename().
+ *
+ * These two options correspond rather directly to the 'dist' and
+ * 'built' terminology that automake uses and are explicitly used to
+ * distinguish between the 'srcdir' and 'builddir' being separate. All
+ * files in your project should either be dist (in the
+ * <literal>DIST_EXTRA</literal> or <literal>dist_schema_DATA</literal>
+ * sense, in which case they will always be in the srcdir) or built (in
+ * the <literal>BUILT_SOURCES</literal> sense, in which case they will
+ * always be in the builddir).
+ *
+ * Note: as a general rule of automake, files that are generated only as
+ * part of the build-from-git process (but then are distributed with the
+ * tarball) always go in srcdir (even if doing a srcdir != builddir
+ * build from git) and are considered as distributed files.
