Here is what I'm trying to do and most of the time I succeed:
Basically I'm signing in on a website and then wait for a class to be in the source, then process the source code.
The exception I get:
Traceback (most recent call last):
File "foo.py", line 495, in <module>
report(login, password)
File "foo.py", line 430, in report
data = bar(login, password)
File "foo.py", line 113, in
ui.WebDriverWait(browser, 10).until(lambda browser: browser.find_elements_by_class_name("the-class-i-want"))
File "/Library/Python/2.7/site-packages/selenium/webdriver/support/wait.py", line 71, in until
raise TimeoutException(message)
selenium.common.exceptions.TimeoutException: Message: ''
Here is the code:
from selenium import webdriver
import contextlib
from selenium.webdriver.common.keys import Keys
import selenium.webdriver.support.ui as ui
from selenium.webdriver.support.wait import WebDriverWait
with contextlib.closing(webdriver.PhantomJS('phantomjs')) as browser:
browser.get('mywebsite')
login_form = browser.find_element_by_id('login-form')
email = browser.find_element_by_name('login')
password = browser.find_element_by_name('password')
email.send_keys(login)
password.send_keys(password)
password.send_keys(Keys.RETURN)
ui.WebDriverWait(browser, 10).until(lambda browser: browser.find_elements_by_class_name("the-class-i-want"))
I tried this too:
wait_count = 0
while wait_count < 6:
print wait_count
ui.WebDriverWait(browser, 10).until(lambda browser: browser.find_elements_by_class_name("the-class-i-want"))
if browser.find_elements_by_class_name("the-class-i-want"):
break
wait_count += 1
I get the same exception.
I am currently trying this :
wait_count = 0
while wait_count < 6:
try:
ui.WebDriverWait(browser, 10).until(lambda browser: browser.find_elements_by_class_name("the-class-i-want"))
if browser.find_elements_by_class_name("the-class-i-want"):
break
except:
wait_count += 1
continue
I haven't got to the point where it fails, I'm still testing it.
Sorry this is very long. But I'd like to find a pythonic and clean solution to those random timeouts.
Another info that could help too: the signing in process is sometimes very long, but even with a several minutes wait, it throws the exception.
