def test_getting_packet_summary(simple_summary_capture):
    assert isinstance(simple_summary_capture[0], PacketSummary)

    # Since we cannot check the exact fields since they're dependent on wireshark configuration,
    # we'll at least make sure some data is in.
    assert simple_summary_capture[0]._fields

def _packet_from_psml_packet(psml_packet, structure):
    return PacketSummary(structure, psml_packet.findall('section'))
