我正在使用Python3,Flask 0.12和Pytest 3.0.7。
我有一个类似于此的烧瓶应用程序:
class AppInitializer:
def __init__(self):
pass
@staticmethod
def __function_to_be_refreshed():
while True:
try:
time.sleep(5)
except Exception as e:
logger.exception(e)
def create_app(self):
daemon_thread = threading.Thread(target=self.__function_to_be_refreshed)
daemon_thread.daemon = True
daemon_thread.start()
atexit.register(daemon_thread.join)
app_ = Flask(__name__)
return app_
app_initializer = AppInitializer()
app = app_initializer.create_app()
我正在尝试使用pytest测试此应用程序,如下所示:
import unittest
import pytest
class TestCheckPriceRequestAPI(unittest.TestCase):
def setUp(self):
self.app = api.app.test_client()
def test_random(self):
pass
当我使用pytest
运行此测试时,此测试(以及所有其他测试)成功运行但pytest挂起。如何停止运行pytest进程(或者可能杀死守护进程线程)?
答案 0 :(得分:2)
join
命令仅表示线程将一直等到线程完成,但不会完成它。要使用无限循环结束线程,您可以这样做:
class AppInitializer:
def __init__(self):
self._run = True
self._daemon_thread = None
def __function_to_be_refreshed(self):
while self._run:
try:
time.sleep(5)
except Exception as e:
logger.exception(e)
def __shutdown(self):
self._run = False
if self._daemon_thread:
self._daemon_thread.join()
def create_app(self):
self._daemon_thread = threading.Thread(target=self.__function_to_be_refreshed)
...
atexit.register(self.__shutdown)
...
