Question

OS：Ubuntu 14，FF61，geckodriver 0.21.0，python2.7

我的脚本基本上看起来像

display = Display(visible=0, size=(800, 600))
display.start()
browser = wd.Firefox()
try:
    browser.get(url)
    ui.WebDriverWait(browser, 10).until(lambda x: len(x.title) > 1)
except Exception as e:
    print str(e)
    browser.save_screenshot(img_folder + camid + ".png")
    print "get icon type error: " + url
browser.quit()

使用Jenkins随机触发这种样式的多个脚本（很难说出确切的频率是多少），我在“ browser.save_screenshot”，“ browser.quit（）”和“ browser = wd.Firefox”中遇到了异常。（）”。对我来说，这没有任何意义，因为它们每个都可以成功执行。当多个脚本一起运行时，肯定出了点问题。这些脚本可能共享相同的输入，但永远不会写入同一文件。或者一个脚本可以用不同的输入触发两次。

FF + Jenkins：随机的selenium.common.exceptions.SessionNotCreatedException
