Problem with WebdriverWait in python webdriver

[koti]

Hi,

I am having problem in using the python version of the webdriver.

If the webpage has drop-down elements or hidden elements, my python
code not able to detect those elements. For this problem, I found some
solutions in the web as, increasing the implicit wait time or using
the WebDriverWait class. I have tried both, but i didn't find solution
to my problem.

Here is my code:

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.common.exceptions import NoSuchElementException
import unittest, time, re
from selenium.webdriver.support.ui import WebDriverWait

class Bz(unittest.TestCase):
def setUp(self):
self.driver = webdriver.Firefox()
self.driver.implicitly_wait(30)
self.base_url = "http://www.abc.com"
self.verificationErrors = []

def test_bz(self):
driver = self.driver
driver.get(self.base_url)
driver.find_element_by_id("name").clear()
driver.find_element_by_id("name").send_keys("XXXXX")
driver.find_element_by_id("password").clear()
driver.find_element_by_id("password").send_keys("XXXXXXX")

driver.find_element_by_css_selector("input[type=image]").click()
try:
WebDriverWait(driver, 10).until(driver.find_element_by_id("Site
Statistics")).click()
#driver.find_element_by_link_text("Site Statistics").click()
driver.find_element_by_link_text("XXXXX").click()
driver.find_element_by_link_text("2011-09-25").click()
driver.find_element_by_css_selector("#signout > a").click()
finally:
driver.quit()

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

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

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


I got the following error after executing the above code,

Traceback (most recent call last):
File "bz.py", line 23, in test_bz

{"method":"id","selector":"Site Statistics"}' ; Stacktrace: Method
WebDriverError threw an error in

Please help me to get rid of this problem.

Thanks

AFAIK, webdriver can only work on html elements visible on the page. You seem to be trying to work with "hidden" elements.

That's not the proper way to do a webdriver wait in python, it's not actually waiting to call your find. The until method takes a function as an argument. You can do that in a couple ways, here's two:

def findSiteStats(driver):
return driver.find_element_by_id("Site Statistics")

WebDriverWait(driver, 10).until(findSiteStats).click()

Or using a lambda function:

WebDriverWait(driver, 10).until(lambda d : d.find_element_by_id("Site Statistics")).click()

The other question is, does your page really have a HTML element with id="Site Statistics" ?

Hi Luke,
Thanks a lot. It was a silly mistake. As you said there was no element
with such an id . I should have used find_element_by_link_text
instead. (/me first timer). Sorry about that.

Thanks to Krishnan too
