我正在嘗試編寫django請求的測試,這可能需要很長時間才能處理,因此可能會與其他請求交錯。我的計劃是發出長時間運行的請求,並將斷言注入可能會暫停的地方。在Django測試交錯長時間運行的請求
但想在我的單元測試使用線程似乎並沒有很好地工作:
class ThreadTest(test.TestCase):
def thread_test(self):
def printer():
print models.Daemon.objects.count()
d = models.Daemon(url='http://lockss.notadomain:8088')
d.save()
printer()
t = threading.Thread(target=printer)
t.start()
t.join()
打印機()調用工程,我所期待的第一次,但後來從一個線程調用時無法找到表格:
1

我想了解發生了什麼。另外,我想知道是否有更好的策略來測試並行請求。
不確定這是否真的適用於測試,但是您是否考慮過使用celeryd來進行異步處理? – 2011-07-11 20:52:49
傑克可能是正確的,芹菜真的很堅固。 – 2011-07-14 12:37:41
