Python unittestsが複数回実行される

Question

私の問題は、私のunittestsのいくつかは何度も実行されていますが、私はその理由を理解できません。ここで

は、テストとコードです：

# -*- coding: utf-8 -*- 
"""Tests for api.resource.decorators""" 

import os 
import errno 
import unittest 
import logging 
from socket import gaierror, error as socketerror 
from lockfile import LockFile 
from logging import FileHandler, Formatter 
from api.resource.decorators import handle_general_exceptions 


class TestHandleGeneralExceptions(unittest.TestCase): 
    _tmp_log_path = '/tmp/test_handle_general_exceptions_log' 
    _tmp_lock_path = '/tmp/test_handle_general_exceptions_lock' 
    _lock = None 
    _logger = None 

    def setUp(self): 
     self._lock = self._get_lock() 
     self._logger = self._get_logger() 

    def tearDown(self): 
     self._remove_lockfiles() 

    def _remove_lockfiles(self): 
     # TODO: solve without system call 
     os.system('rm -f %s*' % self._tmp_lock_path) 

    def _get_lock(self): 
     return LockFile(self._tmp_lock_path) 

    def _get_logger(self): 
     logger = logging.getLogger('handle_general_exceptions') 
     logger.propagate = False # Only use this Logger 
     handler = FileHandler(self._tmp_log_path) 
     formatter = Formatter('%(asctime)s [%(levelname)s] %(message)s', 
           datefmt='%Y-%m-%d %H:%M:%S') 
     handler.setFormatter(formatter) 
     logger.addHandler(handler) 
     logger.setLevel('INFO') 
     return logger 

    def _raise_gaierror(self): 
     self._lock.acquire(-1) 
     raise gaierror(-2, 'Name or service not known') 

    def _raise_connection_timed_out(self): 
     self._lock.acquire(-1) 
     raise socketerror(errno.ETIMEDOUT, 'Connection Timed Out') 

    def _raise_connection_refused(self): 
     self._lock.acquire(-1) 
     raise socketerror(errno.ECONNREFUSED, 'Connection Refused') 

    def _is_locked(self): 
     return os.path.exists(self._tmp_lock_path + '.lock') == 1 

    def test_not_locked_if_gaierror_occurred(self): 
     self._raise_gaierror = handle_general_exceptions(
      self._lock, self._logger, self._raise_gaierror) 
     self._logger.info('¯¯¯¯¯¯¯¯¯¯¯¯ _raise_gaierror() ¯¯¯¯¯¯¯¯¯¯¯¯') 
     self._raise_gaierror() 
     self._logger.info('____________ End _raise_gaierror() ____________') 
     self.assertFalse(self._is_locked()) 

    def test_not_locked_if_connection_timed_out(self): 
     self._raise_connection_timed_out = \ 
      handle_general_exceptions(self._lock, self._logger, 
       self._raise_connection_timed_out) 
     self._logger.info(
      '¯¯¯¯¯¯¯¯¯¯¯¯ _raise_connection_timed_out() ¯¯¯¯¯¯¯¯¯¯¯¯') 
     self._raise_connection_timed_out() 
     self._logger.info(
      '____________ End _raise_connection_timed_out() ____________') 
     self.assertFalse(self._is_locked()) 

    def test_not_locked_if_connection_refused(self): 
     self._raise_connection_refused = \ 
      handle_general_exceptions(self._lock, self._logger, 
       self._raise_connection_refused) 
     self._logger.info(
      '¯¯¯¯¯¯¯¯¯¯¯¯ _raise_connection_refused() ¯¯¯¯¯¯¯¯¯¯¯¯') 
     self._raise_connection_refused() 
     self._logger.info(
      '____________ End _raise_connection_refused() ____________') 
     self.assertFalse(self._is_locked()) 

そしてテストは、このようなスクリプトを介して実行されます。

#!/bin/sh 

python -m unittest discover api.tests -t . 

今テストtest_not_locked_if_gaierror_occurred()が3回実行されます。

テストtest_not_locked_if_connection_timed_out()が2回実行されます。

そして、テストtest_not_locked_if_connection_refused()が1回実行されます。ログの出力だ

Answer 1

問題私自身は、テストを複数回実行されませんでしたが見つかりました。 奇妙なログ出力の理由は、すべてのテストで同じロガーを使用したためです。

私はこの

def _get_logger(self, logger_suffix): 
    logger = logging.getLogger('handle_general_exceptions' + logger_suffix) 

この道のようなものに次の

def _get_logger(self): 
    logger = logging.getLogger('handle_general_exceptions') 

を変更しなければならなかった、それはまだ一つだけのファイルに記録しますが、それは別のロガーを使用しています。
