This is what I have:
from selenium import webdriver
driver = webdriver.Firefox()
How can I let the geckodriver open minimized or hidden?
You have to set the firefox driver options to headless so that it opens minimized. Here is the code to do that.
fireFoxOptions = webdriver.FirefoxOptions()
fireFoxOptions.set_headless()
driver = webdriver.Firefox(firefox_options=fireFoxOptions)
If this doesn't work for you there are other methods that you can use. Check out this other SO question for those: How to make firefox headless programmatically in Selenium with python?
geckodriver
geckodriver in it's core form is a proxy for using W3C WebDriver-compatible clients to interact with Gecko-based browsers.
This program provides the HTTP API described by the WebDriver protocol to communicate with Gecko browsers, such as Firefox. It translates calls into the Firefox remote protocol by acting as a proxy between the local- and remote ends.
So more or less it acts like a service. So the question to minimize the GeckoDriver shouldn't arise.
Minimizing Mozilla Firefox browser
The Selenium driven GeckoDriver initiated firefox Browsing Context by default opens in semi maximized mode. Perhaps while executing tests with the browsing context being minimized would be against all the best practices as Selenium may loose the focus over the Browsing Context and an exception may raise during the Test Execution.
However, Selenium's python client does have a minimize_window() method which eventually minimizes the Chrome Browsing Context effectively.
Solution
You can use the following solution:
Firefox:
from selenium import webdriver
options = webdriver.FirefoxOptions()
options.binary_location = r'C:\Program Files\Mozilla Firefox\firefox.exe'
driver = webdriver.Firefox(firefox_options=options, executable_path=r'C:\WebDrivers\geckodriver.exe')
driver.get('https://www.google.co.in')
driver.minimize_window()
Chrome:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("--start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://www.google.co.in')
driver.minimize_window()

What I need
I need to run Selenium with Chrome Profile
Here is my code:
from selenium import webdriver
import time
options = webdriver.ChromeOptions()
options.add_argument("--user-data-dir=/home/atom/.config/google-chrome") #Path to your chrome profile
options.add_argument('--profile-directory=Profile 1')
driver = webdriver.Chrome(options=options)
driver.get('https://youtube.com')
time.sleep(5)
Problem
The code opens Google Chrome instead of Chromedriver. Profile is loaded. But driver.get doesn't work
Question
How can I use Selenium with Chrome profile?
What chromedriver does is briefly described here. When you call get on the webdriver, you are asking for the site to be opened on the chrome browser. If you want to use brave browser or another browser implementation using the chromium engine, you may specify the location of the browser's binary using:
ChromeOptions options = new ChromeOptions();
options.setBinary("/path/to/other/chrome/binary");
You may load a specific profile by using:
ChromeOptions options = new ChromeOptions();
options.addArguments("user-data-dir=/path/to/your/custom/profile");
Specifying no profile (not including this option should load the default profile).
A complete list of supported options may be found here.
def __init__(self):
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=bot_data")
options.add_argument("--headless") # Runs Chrome in headless mode.
options.add_argument('--no-sandbox') # Bypass OS security model
options.add_argument('--disable-gpu') # applicable to windows os only
options.add_argument('start-maximized') #
options.add_argument('disable-infobars')
options.add_argument("--disable-extensions")
# self.driver = webdriver.Chrome(ChromeDriverManager().install(), options=options)
self.driver = webdriver.Chrome('chromedriver.exe',
options=options)
self.driver.get('https://www.google.com')
self.wait = WebDriverWait(self.driver, 10)
There is have my codes. I want to change it to headless browser. But i am getting an error.
I added screenshot to show error.
This error message...
ERROR:devtools_http_handler.cc(288)] Error writing DevTools active port to file
...implies that there was an error while writing DevTools active port to the required file.
As per the discussion in How to open a Chrome Profile through Python instead of specifying only the directory name through user-data-dir, you need to pass the absolute path of the user-data-dir.
Solution
So you need to replace the line of code:
options.add_argument("user-data-dir=bot_data")
With:
options.add_argument("user-data-dir=C:\\Users\\AtechM_03\\AppData\\Local\\Google\\Chrome\\User Data\\bot_data")

When I run chrome driver from selenium the browser opens in minimized windows. but I want it to open by default as maximized
You can either use
driver.maximize_window() or
chrome_options.add_argument("--start-maximized") which will maximize the browser when ever it opens.
The following code was taken from this link. https://pythonbasics.org/selenium-maximize/
from selenium import webdriver
import time
driver = webdriver.Firefox()
driver.maximize_window()
time.sleep(5)
driver.get("https://www.python.org")
This is one of the methods to do so.
I'm using Chrome with Selenium in Python 2.7.
I've tried to run Chrome in headless mode but it slows down my tests significantly.
One workaround shall be to disable the proxy settings but I don't know how to do it in python.
This is my code so far:
from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument('headless')
chrome_options.add_argument('--hide-scrollbars')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('???') # which option?
self.driver = webdriver.Chrome("C:\Python27\Scripts\chromedriver.exe", chrome_options=chrome_options)
Does anyone know how to solve this?
Try this:
chrome_options.add_argument('--no-proxy-server')
I am currently trying to code a basic smartmirror for my coding II class in high school with python. One thing I'm trying to do is open new tabs in full screen (using chrome). I currently have it so I can open url's, but I am not getting them in full screen. Any ideas on code I can use to open chrome in full screen?
If you're using selenium, just code like below:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://google.com')
driver.maximize_window()
As suggested, selenium is a good way to accomplish your task.
In order to have it full-screen and not only maximized I would use:
chrome_options.add_argument("--start-fullscreen");
or
chrome_options.add_argument("--kiosk");
First option emulates the F11 pressure and you can exit pressing F11. The second one turns your chrome in "kiosk" mode and you can exit pressing ALT+F4.
Other interesting flags are:
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
Those will remove the top bar exposed by the chrome driver saying it is a dev chrome version.
The complete script is:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_experimental_option("useAutomationExtension", False)
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
# chrome_options.add_argument("--start-fullscreen");
chrome_options.add_argument("--kiosk");
driver = webdriver.Chrome(executable_path=rel("path/to/chromedriver"),
chrome_options=chrome_options)
driver.get('https://www.google.com')
"path/to/chromedriver" should point to the chrome driver compatible with your chrome version downloaded from here
