Я использую pytest для запуска некоторых тестов моего проекта. Иногда (примерно от 30 до 50%) я получаю сообщение об ошибке после завершения теста. Но это не позволяет системе тестирования создать тестовый отчет, что действительно доставляет неудобства.
Ошибка:
Windows fatal exception: access violation

Кто-нибудь знает, как это исправить или отладить?
Я использую pytest 5.4.1 с Python 3.8.0 на Win10. Но это также можно воспроизвести и в более старых версиях pytest.
Плагин плагин_zigbee_dongle.py использует pyserial (3.4) для связи с USB-RF-ключом в потоке. Следующий код представляет собой фрагмент этого плагина:
import serial
import threading
class ZigbeeDongleSerial(object):
def __init__(self, test_engine):
self.ser = serial.Serial()
self.test_engine = test_engine
# ----------------------------------------------------------
def connect(self,
port,
baud,
timeout):
self.ser.baudrate = baud
self.ser.timeout = timeout
self.ser.port = port
self.ser.open()
# ----------------------------------------------------------
def disconnect(self):
try:
if self.is_connected():
self.ser.close() #
