Django与splinter和phantomjs是痛苦的慢 [英] Django with splinter and phantomjs is painfully slow

问题描述

今天我尝试将django的 LiveServerTestCase 与 splinter 和 phantomjs webdriver。

Today I tried combining django's LiveServerTestCase with splinter and phantomjs webdriver.

这是我做的（简化版）：

Here's what I do (simplified version):

class Test(LiveServerTestCase):

    def setUp(self):
        self.browser = Browser('phantomjs')

    def tearDown(self):
        self.browser.quit()

    def test(self):
        self.browser.visit(self.live_server_url)
        self.assertIn("Hello world!", self.browser.title)

有时测试运行正常 - 即使每次测试需要一秒执行方法但是有时可以随意花费大约100秒钟来执行单一的测试方法，否则它会冻结，直到我忍耐等待完成。

Sometimes tests run fine - even though taking a second per test method to execute. But sometimes it can randomly take ~100 seconds for that single test method to execute, or it just freezes until I am out of patience to wait for it to finish.

我使用 django_nose 作为测试运行器，我通过 - liveserver = localhost：8081-8181 端口范围为 ./ manage.py test 命令。

I use django_nose as a test runner, and I pass --liveserver=localhost:8081-8181 range of ports to ./manage.py test command.

有没有办法加速？有没有其他web测试运行器可以哪个更快？

Is there any way to speed it up? Is there other web test runner I can which is faster?

默认网络驱动程序似乎更加可靠，速度（每个测试方法1-3秒），但它是还是很慢我也更喜欢一个无头浏览器进行测试。

Default web driver seem to be more reliable speed-wise (1-3 seconds per test method), but it's still pretty slow. I also would prefer a headless browser for testing.

推荐答案

什么让测试缓慢打开并关闭每个测试的浏览器。改进测试时间的方法是打开浏览器一次。你可以使用setUpClass和tearDownClass来实现。

What makes the tests slow is open and close the browser on each test. A way to improve the tests time is open the browser once. You can do it using setUpClass and tearDownClass.
