使用PhantomJS代替Selenium Firefox

我使用的是一个使用seleniumfirefox驱动程序在Python中生成的简单测试。 我想让Firefox静音,所以我用了幻影。 这段代码在Firefox上运行得很好,但在PhantomJS中却不是这样。在

# -*- coding: utf-8 -*-
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import NoAlertPresentException

import unittest, time, re

class Webdriver(unittest.TestCase):
    def setUp(self):
        #self.driver = webdriver.Firefox()
        self.driver = webdriver.PhantomJS()
        self.driver.implicitly_wait(30)
        self.base_url = "https://www.google.fr/"
        self.verificationErrors = []
        self.accept_next_alert = True

    def test_webdriver(self):
        driver = self.driver
        driver.get(self.base_url + "/?gfe_rd=cr&ei=SuqkVv2gJ4_u8wfRjbnIBg&gws_rd=ssl")
        driver.find_element_by_id("lst-ib").clear()
        driver.find_element_by_id("lst-ib").send_keys("this is a test")

    def is_element_present(self, how, what):
        try: self.driver.find_element(by=how, value=what)
        except NoSuchElementException as e: return False
        return True

    def is_alert_present(self):
        try: self.driver.switch_to_alert()
        except NoAlertPresentException as e: return False
        return True

    def close_alert_and_get_its_text(self):
        try:
            alert = self.driver.switch_to_alert()
            alert_text = alert.text
            if self.accept_next_alert:
                alert.accept()
            else:
                alert.dismiss()
            return alert_text
        finally: self.accept_next_alert = True

    def tearDown(self):
        self.driver.quit()
        self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
    unittest.main()

这是我的错误:

根据@alecxe的响应,向PhantomJS添加一个代理对某些测试有效,但在其他测试中失败。在

错误消息是:

假装不是带有自定义User-Agent头的PhantomJS

dcap = dict(webdriver.DesiredCapabilities.PHANTOMJS)
dcap["phantomjs.page.settings.userAgent"] = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.57 Safari/537.36"
self.driver = webdriver.PhantomJS(desired_capabilities=dcap)

为我工作。在


您还可以通过添加fluent explicit waits来改进测试。例如,等待元素可见:
