How to use the testinfra.utils function in testinfra

# A literal IPv6 address might be like
        #  [fe80:0::a:b:c]:80
        # thus, below in words; if this starts with a '[' assume it
        # encloses an ipv6 address with a closing ']', with a possible
        # trailing port after a colon
        if name.startswith('['):
            name, port = name.split(']')
            name = name[1:]
            if port.startswith(':'):
                port = port[1:]
            else:
                port = None
        else:
            if ':' in name:
                name, port = name.split(':', 1)
        name = testinfra.utils.urlunquote(name)
        if user is not None:
            user = testinfra.utils.urlunquote(user)
        if password is not None:
            password = testinfra.utils.urlunquote(password)
        return HostSpec(name, port, user, password)
