Selenium wait.u do sprawdzenia wniosku ajax zakończył się błąd wyświetlania

Question

w selorze Webdriver z pythonem, chcę poczekać na zakończenie żądania Ajax (biblioteka jquery). Używam funkcji wait.until() Selenium. Żądanie Ajax jest uruchamiane po kliknięciu przycisku submitJquery.

wait.until(self.driver.execute_script("return jQuery.active == 0")) 

ale mam następujący błąd:

E 
====================================================================== 
ERROR: test_MahsumAkbasNet_Pass (__main__.TestClass)

kompletny kod jest:

    def setUp(self): 
     self.driver = webdriver.Firefox() 
     self.driver.set_page_load_timeout(30) 
     self.driver.maximize_window() 

    def test_MahsumAkbasNet_Pass(self): 
     wait = WebDriverWait(self.driver, 30) 

     self.driver.get("http://www.mahsumakbas.net/selenium") 

     self.driver.find_element_by_id("submitJquery").click()  

     wait.until(self.driver.execute_script("return jQuery.active == 0")) 

     print "Jquery is completed" 

    def tearDown(self): 
     self.driver.close() 

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

góry dzięki.

Trzeba zdać wywoływalnym do wait.until():

wait.until(lambda driver: driver.execute_script("return jQuery.active == 0"))
