python硒测试网页:确实执行缓慢 [英] webpage test with python selenium: really slow execution

问题描述

我用Python用Selenium编写了一个非常简单的网页测试

I wrote, in Python, using Selenium, a very simple test of a webpage

这里的代码:

from selenium import webdriver
import unittest
from selenium.webdriver.common.keys import Keys

class NewVisitorTest(unittest.TestCase):

    def setUp(self):
    # cose da fare prima dei test
        self.browser = webdriver.Firefox()  # Opera? credo sia usabile :D

    def tearDown(self):
    # cose da fare dopo dei test
        self.browser.quit()

    def test_yahoo(self):
        # browser = webdriver.Firefox() # Get local session of firefox
        pagina = "http://ricordandoti.net/it/app-per-scoprire-il-cimitero-del-poblenou/"
        self.browser.get(pagina)      # Load page
        self.browser.implicitly_wait(5)    # aspetto si carichi tutta la pagina
                                           # forzando di aspettare 3 s
        assert "Ricordandoti" in self.browser.title


if __name__ == '__main__':  # 7    
    unittest.main(warnings='ignore')

它可以工作，但是几乎要花一分钟时间才能执行:

It works, but it takes almost a minute to be executed:

我使用ninja IDE编写代码(在Ubuntu 14.04计算机中). 这似乎是原因.

I use ninja IDE to write the code (in a Ubuntu 14.04 machine). This seems to be the reason.

直接从shell执行代码，需要20 s:

Executing code directly from shell, it takes 20 s:

> subu@VR46-U:~$ python3 "/home/.../tests/functional_tests_ricord.py"
.
----------------------------------------------------------------------
Ran 1 test in 20.865s

OK

我该如何加快执行速度?

What can I do to fast up the execution?

推荐答案

以下内容将为您加快速度:

The following should speed things up for you:

• 将selenium升级到最新版本(当前为2.44.0)

• upgrade selenium to the latest version (currently 2.44.0)

pip3 install selenium --upgrade

将firefox升级到最新版本(当前为35.0)

upgrade firefox to the latest version (currently 35.0)

升级之前，我的速度较慢，现在是:

It was slower on my end before the upgrades, now it is:

$ python3 test.py
.
----------------------------------------------------------------------
Ran 1 test in 6.258s

OK
