全局名称未得到定义-python

我正在尝试运行以下命令：

import unittest
import wd.parallel
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.common.exceptions import WebDriverException
import copy
class Selenium2OnSauce(unittest.TestCase):
    def setUp(self):
        desired_capabilities = []

        browser = copy.copy(webdriver.DesiredCapabilities.FIREFOX)
        browser['version'] = '10'
        browser['platform'] = 'XP'
        browser['name'] = 'Python at Sauce'
        browser['tags'] = "Parallel"
        desired_capabilities += [browser]

        self.drivers = wd.parallel.Remote(
            desired_capabilities=desired_capabilities,
            command_executor="http://user-string:key-string@ondemand.saucelabs.com:80/wd/hub"
        )

    def ajax_complete(driver):
        try:
            return 0 == driver.execute_script("return JQuery.active")
        except WebDriverException:
            pass    

    @wd.parallel.multiply
    def test_sauce(self):
        self.driver.get('http://url.com')
        username = self.driver.find_element_by_id('id_username')
        print "Found Username"
        username.send_keys('i1@example.com')
        print "Username Entered"

        password = self.driver.find_element_by_id('id_password')
        print "Found Password"
        password.send_keys('testuser')        
        print "Password Entered"

        password.submit()
        print "Logged in"

        self.driver.find_elements_by_link_text('Notification')[0].click()
        print "Going to Notification"

        WebDriverWait(self.driver, 10).until(
            ajax_complete, "Timeout waiting for page to load"
        )

        print "ajax loaded string" in self.drive.page_source

    @wd.parallel.multiply
    def tearDown(self):
        print("Link to your job: https://saucelabs.com/jobs/%s" % self.driver.session_id)
        self.driver.quit()
        print "Quit"

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

当我这样做时，我得到了：

Found Username

我想我在访问var调用

ajax\u complete

时遇到了问题，但我不知道为什么

最后，我想做的是等待所有ajax完成，然后再运行下一个测试

注意：我是python新手，很抱歉，这个问题真的很傻。

python中的方法可以通过

self

访问：

WebDriverWait(self.driver, 10).until(
    self.ajax_complete, "Timeout waiting for page to load"
)

---

请注意，

ajax\u complete

方法本身也需要将

self

作为第一个参数。

或者，

ajax\u complete

可以定义为类外的函数或静态方法。如下所示：

def ajax\u complete（self）：try:return 0==self.driver.execute\u脚本（“return JQuery.active”）除了WebDriverException:pass
