关于在文件中存储控制台输出：将控制台输出存储在文件中 – Python，unittest

Store console output in a file - Python , unittest

我有一个python脚本，其中编写了一些单元测试，并且使用了Selenium。

我想提取控制台的整个输出(不仅是我的打印结果，还有与单元测试相关的结果)，以便稍后在我的测试管理工具中导入它们。

这是我的代码：

import unittest
from selenium import webdriver
import json
import requests
import sys

class TestUbuntuHomepage(unittest.TestCase):
global strs

strs = []

def setUp(self):
sys.stdout = open("C:\\Users\\Marialena\\Downloads\\out2.log", 'wt')

self.driver = webdriver.Firefox(executable_path="C:\\Users\\Marialena\\Downloads\\selenium-drivers\\geckodriver")

def testTitle(self):
self.driver.get('http://www.ubuntu.com/')

if self.assertIn('Ubuntu', self.driver.title):
strs.append('test'})

def tearDown(self):
self.driver.quit()

if __name__ == '__main__':
unittest.main(verbosity=2)

使用sys.stdout = open("C:\\Users\\Marialena\\Downloads\\out2.log", 'wt')，我将所有已打印的内容都保存在文件中，并且也会得到以下例外：

有什么帮助吗？谢谢您。
