IOError: [Errno 9] Bad file descriptor using robot framework with Python

Question

我正在尝试运行以下 Python 2.7.10 代码在 Win7 上：

from robot import run

run("Login.robot", variable=['USERNAME:testuser@fakemail.com'])

Login.robot 是一个非常简单的机器人框架测试，打开浏览器 window，加载我们的登录页面，输入用户名和密码，然后确认用户已登录。我有通过使用 pybot 和测试套件运行s 从命令行运行正确测试它。但是尝试从这个脚本运行测试套件生成

Traceback (most recent call last):

self._highlight('[ ', level, ' ] ' + message, error=True)

  File "C:\Python27\lib\site-packages\robot\output\monitor.py", line 154, in _write
stream.flush()
IOError: [Errno 9] Bad file descriptor

有什么建议吗？我试过使用机器人文件的绝对路径、单引号、双引号、通过打开的文件对象引用、通过关闭的文件对象引用。谢谢！

Answer 1

我发现这是由于使用了 IDLE，它阻止了机器人框架写入控制台。我的脚本在从 Windows 命令行启动时运行。

Answer 2

打开文件句柄并在句柄打开时调用内部的 robot.run 方法。希望这能解决您的问题。

mydir = os.path.join('c:/','....')
os.makedirs(mydir)    
with open('mydir', 'w') as stdout_file:
            k = run("Login.robot", 
                     variable=['USERNAME:testuser@fakemail.com'],
                     stdout=stdout_file)
