## `Union` or `anyOf` { #union-or-anyof }

You can declare a response to be the `Union` of two or more types, that means, that the response would be any of them.

It will be defined in OpenAPI with `anyOf`.

To do that, use the standard Python type hint [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union):

    openapi = app.openapi()
    body_model_name = get_body_model_name(openapi, path)

    assert app.openapi()["components"]["schemas"][body_model_name] == {
        "properties": {
            "p": {
                "anyOf": [{"type": "string"}, {"type": "null"}],
                "title": "P",
            },
        },
        "title": body_model_name,
        "type": "object",
    }


@pytest.mark.parametrize(
    "path",

                    assertThat(entry.getLinkName(), anyOf(equalTo("../real-folder/file"), equalTo("..\\real-folder\\file")));
                    linkInFolderLinkToFileEntry = true;
                } else if (entry.getName().equals("link-to-real-folder")) {
                    assertTrue(entry.isSymbolicLink());
                    assertThat(entry.getLinkName(), anyOf(equalTo("./real-folder"), equalTo(".\\real-folder")));
