我在使用selenium和PhantomJS驅動程序運行單元測試時遇到問題。它似乎與PhantomJS流程中stderr/stdout的資源爭用有關。錯誤是：「IOError：[Errno 35]資源暫時不可用」，使用PhantomJS，python，selenium，unittest
$ python -m unittest selenium_failure.SeleniumTestCase

更詳細的要點在這裏：https://gist.github.com/lucaswiman/9788422
import unittest
import logging
from selenium.webdriver import phantomjs
import sys
class SeleniumTestCase(unittest.TestCase):
def setUp(self):
self.selenium = phantomjs.webdriver.WebDriver()
def tearDown(self):
self.selenium.quit()
def test_that_something_fails(self):
self.selenium.get('https://www.google.com')
print repr(self.selenium.get_log('browser'))
print repr(self.selenium.get_log('har'))
raise AssertionError()
的錯誤是可重複使用的OS X是要點，而不是在Ubuntu 12.04。我相信這不是特定於OS X的，因爲我們在Ubuntu上運行集成測試時看到類似的錯誤，儘管我沒有能夠以獨立的形式重現它。
