+XXX-PYOXIDIZER since the frozen binary does not have source directory tree,
+this make the checking for actual file under `hgext` a bit complicated. In
+addition these tests do some strange dance to ensure some other module are the
+first in `sys.path` (since the current install path is always in front
+otherwise) that are fragile and that does not match reality in the field. So
+for now we disable this test untill a deeper rework of that logic is done.
