How to use the catalogue.REGISTRY function in catalogue

def test_entry_points():
    # Create a new EntryPoint object by pretending we have a setup.cfg and
    # use one of catalogue's util functions as the advertised function
    ep_string = "[options.entry_points]test_foo\n    bar = catalogue:check_exists"
    ep = catalogue.importlib_metadata.EntryPoint._from_text(ep_string)
    catalogue.AVAILABLE_ENTRY_POINTS["test_foo"] = ep
    assert catalogue.REGISTRY == {}
    test_registry = catalogue.create("test", "foo", entry_points=True)
    entry_points = test_registry.get_entry_points()
    assert "bar" in entry_points
    assert entry_points["bar"] == catalogue.check_exists
    assert test_registry.get_entry_point("bar") == catalogue.check_exists
    assert catalogue.REGISTRY == {}
    assert test_registry.get("bar") == catalogue.check_exists
    assert test_registry.get_all() == {"bar": catalogue.check_exists}
    assert "bar" in test_registry

def cleanup():
    catalogue.REGISTRY = {}
    yield
