g_assert_finalize_object() in GLib 2.61.2

One more API in this mini-series! g_assert_finalize_object(), which is available in GLib 2.61.2, which was released today.

This one’s useful when writing tests (and only when writing tests). It’s been put together by Simon McVittie to implement the common pattern needed in tests, where you want to unref a GObject and assert that you just dropped the final reference to the object — i.e., check that no references to the object have been leaked in the test.

Use it in place of g_object_unref(). If G_DISABLE_ASSERT is defined, it will actually just be a call to g_object_unref().

Here’s an example usage of it, straight out of the GLib unit test for it:

static void
test_assert_finalize_object (void)
{
  GObject *obj = g_object_new (G_TYPE_OBJECT, NULL);

  /* do some things with the obj here */

  g_assert_finalize_object (obj);
}
