How to use the mwparserfromhell.utils.parse_anything function in mwparserfromhell

tests = [
            (wraptext("foobar"), wraptext("foobar")),
            (Template(wraptext("spam")), wrap([Template(wraptext("spam"))])),
            ("fóóbar", wraptext("fóóbar")),
            (b"foob\xc3\xa1r", wraptext("foobár")),
            (123, wraptext("123")),
            (True, wraptext("True")),
            (None, wrap([])),
            ([Text("foo"), Text("bar"), Text("baz")],
             wraptext("foo", "bar", "baz")),
            ([wraptext("foo"), Text("bar"), "baz", 123, 456],
             wraptext("foo", "bar", "baz", "123", "456")),
            ([[[([[((("foo",),),)], "bar"],)]]], wraptext("foo", "bar"))
        ]
        for test, valid in tests:
            self.assertWikicodeEqual(valid, parse_anything(test))

This follows the same rules as :meth:`_do_strong_search` with some
        differences. *obj* is treated as a string that might represent any
        :class:`.Node`, :class:`.Wikicode`, or combination of the two present
        in the node list. Thus, matching is weak (using string comparisons)
        rather than strong (using ``is``). Because multiple nodes can match
        *obj*, the result is a list of tuples instead of just one (however,
        :exc:`ValueError` is still raised if nothing is found). Individual
        matches will never overlap.

        The tuples contain a new first element, *exact*, which is ``True`` if
        we were able to match *obj* exactly to one or more adjacent nodes, or
        ``False`` if we found *obj* inside a node or incompletely spanning
        multiple nodes.
