我正在使用Selenium Firefox驱动程序在Python中生成的简单测试。 我想让Firefox保持沉默,所以我使用了PhantomJS。 该代码适用于Firefox,但PhantomJS并非如此。

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()
这是我得到的错误:

修改
根据@alecxe的回复,向PhantomJS添加代理程序可以进行一些测试但是却失败了。
错误消息是:

}
答案 0 :(得分:2)
假装不是PhantomJS
使用自定义User-Agent
标题:
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。
您还可以通过添加fluent explicit waits来改进测试。例如,等待元素可见:
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
element = WebDriverWait(driver, 10).until(
EC.visibility_of_element_located((By.ID, "lst-ib"))
)
element.clear()
element.send_keys("this is a test")
