The main idea is to simplify management of binary drivers for different browsers.
For now support:
-
ChromeDriver
-
GeckoDriver
-
IEDriver
-
OperaDriver
-
EdgeChromiumDriver
Before: You should download binary chromedriver, unzip it somewhere in you PC and set path to this driver like this:
webdriver.Chrome('/home/user/drivers/chromedriver')
ChromeDriverManager(path=custom_path).install()It’s boring!!! Moreover every time the new version of driver released, you should go and repeat all steps again and again.
With webdriver manager, you just need to do two simple steps:
Install manager:
pip install webdriver-managerUse with Chrome:
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())Use with Chromium:
from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
from webdriver_manager.utils import ChromeType
driver = webdriver.Chrome(ChromeDriverManager(chrome_type=ChromeType.CHROMIUM).install())Use with FireFox:
from selenium import webdriver
from webdriver_manager.firefox import GeckoDriverManager
driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())Use with IE
from selenium import webdriver
from webdriver_manager.microsoft import IEDriverManager
driver = webdriver.Ie(IEDriverManager().install())Use with Edge
from selenium import webdriver
from webdriver_manager.microsoft import EdgeChromiumDriverManager
driver = webdriver.Edge(EdgeChromiumDriverManager().install())Use with Opera
from selenium import webdriver
from webdriver_manager.opera import OperaDriverManager
driver = webdriver.Opera(executable_path=OperaDriverManager().install())If the Opera browser is installed in a location other than C:/Program Files or C:/Program Files (x86) on windows and /usr/bin/opera for all unix variants and mac, then use the below code,
from selenium import webdriver
from webdriver_manager.opera import OperaDriverManager
options = webdriver.ChromeOptions()
options.add_argument('allow-elevated-browser')
options.binary_location = "C:\\Users\\USERNAME\\FOLDERLOCATION\\Opera\\VERSION\\opera.exe"
driver = webdriver.Opera(executable_path=OperaDriverManager().install(), options=options)If you face error related to github credentials, you need to place github token: (*)
Example:
export GH_TOKEN = "asdasdasdasd"(*) access_token required to work with Github API more info https://help.github.com/articles/creating-an-access-token-for-command-line-use/.
There is also possibility to set same variables via ENV VARIABLES.
To silent webdriver_manager logs and remove them from console, initialize env variable WDM_LOG_LEVEL with '0' value before your selenium tests:
import os
os.environ['WDM_LOG_LEVEL'] = '0'or via constructor:
ChromeDriverManager("2.26", log_level=0).install()By default webdriver manager prints a blank space before its log output if logging is enabled. If you want to disable this, initialize WDM_PRINT_FIRST_LINE with 'False' before your tests:
import os
os.environ['WDM_PRINT_FIRST_LINE'] = 'False'or via constructor:
ChromeDriverManager("2.26", print_first_line=False).install()By default all driver binaries are saved to user.home/.wdm folder. You can override this setting and save binaries to project.root/.wdm.
import os
os.environ['WDM_LOCAL'] = '1'
Driver cache by default is valid for 1 day. You are able to change this value using constructor parameter:
ChromeDriverManager("2.26", cache_valid_range=1).install()This will make your test automation more elegant and robust!
