python - Jenkins Python 打印控制台输出

Question

尝试通过测试用例在 Jenkins 中打印“已登录”文本，例如:

import unittest
from #path.to.methods import method
Class TC1(unittest.TestCase):
    def test_tc01(self):
        self.driver = webdriver.chrome()
        driver = method(self.driver)
        driver.login()
        print ("Logged in") 

在 Jenkins 中，我的构建执行 Shell 命令如下:

cd path/to/test
py.test --cov

目前 Jenkins 控制台输出不显示打印语句，但当我在个人计算机上运行它时它会显示

您可以在 python 脚本的开头添加以下内容吗:

#!/usr/bin/env python -u

-u 的作用:

 python -u
-u     Force  stdin,  stdout  and stderr to be totally unbuffered.  On systems where it matters, also put
       stdin, stdout and stderr in binary mode.  Note that there is internal buffering  in  xreadlines(),
       readlines()  and  file-object  iterators ("for line in sys.stdin") which is not influenced by this
           option.  To work around this, you will want to use  "sys.stdin.readline()"  inside  a  "while  1:"
           loop.

或者:

import unittest
import sys #<--this 
from #path.to.methods import method
Class TC1(unittest.TestCase):
    def test_tc01(self):
        self.driver = webdriver.chrome()
        driver = method(self.driver)
        driver.login()
        print ("Logged in")
        sys.stdout.flush() #<--and this
