当我在crontab中安排下面的命令时，测试用例运行正常。但它不会写下面指定的日志文件。
30 03 * * * user cd /home/common_setupwise_testcases && bash setup_wise_test.sh >> /home/testing/cron_logs/setup_wise_test_cases.log
我已经尝试过这个：/home/testing/cron_logs/setup_wise_test_cases.log 2>&1，我得到了这个输出：
{"timestamp": "2017-10-23T10:25:01.387967Z", "event": "2017-10-23", "_": {"ln": 34, "file": "common_mail_triggering.py", "name":"__main__", "fn": "sub_process"}, "level": "error"}
但我希望以下格式存储在logfile
中test_logout (testing_logout.LogOut) ... ok

Ran 1 test in 5.458s
