from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://www.google.com')
Can someone help me with the above code. I expect this code to open a new tab in Firefox with google.com; instead this opens a new Internet Explorer tab.
Setting up geckodriver for Selenium Python resolves the issue I think.
It needs to set geckodriver path with FirefoxDriver as below code:
self.driver = webdriver.Firefox(executable_path = 'PATH\TO\geckodriver.exe')
Download geckodriver for your suitable OS from https://github.com/mozilla/geckodriver/releases
Extract it in a folder of your choice
Set the path correctly as mentioned above
IEDriverServer and GeckoDriver both of the WebDriver variants being/getting W3C Compliant and evolving with each day, it is quite possible that trying to use one of the variants gets hooked to other variant of Web Browser because of the following reasons :
Your Automated Tests may be running in an environment which is Manually Intervened by opening/closing of Internet Explorer and Firefox Web Browsers.
You have a (couple of) dangling instance of IEDriverServer within your system which needs to be cleaned up.
Solution :
Here are a few possible solutions for the issue you are facing :
Always be explicit mentioning the absolute location of the GeckoDriver while initializing the WebDriver / Web Browser instance as follows :
driver=webdriver.Firefox(executable_path=r'C:\path\to\geckodriver.exe')
Within the tearDown() method of your Test Execution always use quit() as follows :
driver.quit()
Before you start the Test Execution ensure there are no dangling instances of any WebDriver variant.
Incase your Test Framework leaves any dangling instances add the following Windows Based Command at the end of your script to kill the dangling WebDriver.
taskkill /F /IM <webdriver_variant>.exe /T
Periodically Cleanup your Project WorkSpace in your IDE.
Run CCleaner tool to wipe away all the OS chores before and after Test Execution.
When you uninstall any Browser (any Software) from your system use Revo Uninstaller which cleans up your Unused Registry Settings as well.

How to use normal chrome completely without chromedriver selenium python not duplicate.
I am using python 3.8.8,os is windows 7 ultimate with pycharm as
IDE and chrome version is around 96. and my problem is that whenever I use my python script to scrape a website it uses chromedriver and when I specify what's given below:
options = Options ()
options.add_argument(r"user-data-dir=my chrome path which is not Executable instead the user data")
#this works but when opening chrome it shows "browser is controlled by automated software" and changing it to normal chrome. Exe won't work
Sure it uses normal chrome with my credentials but it still needs chromedriver to work and when I delete the chromedriver it throw an error and when I go into selenium source code in a file called site.py(or sites.py) which I changed the variable self. executable to chrome.exe path and it worked and it won't show the message browser is controlled by automated software but it won't do anything , it is just stuck there and what I want to do is use chrome as the browser to scrape without chromedriver in my pc is it possible? If yes please tell me how should I go on to do it and you can ask for further Clarification and details and Thanks in advance
By default, selenium is detected as an automated software and is flagged by most websites, and the flag is unable to be removed. There are, however, external libraries that can be installed that can remove the flag.
There are options here to try to get around the default flag and hide the fact the browser is automated.
Edit
I understand the question further, and see that you want a more portable chrome option. Chrome driver is a very specific program controlled by selenium and must be used. There is no substitute. You can use Firefox driver or internet explorer, but a webdriver must be used (hence the name driver for driving the main browser). When you specify the directory for the Chrome binary, you aren’t removing the middleman of the chromedriver, only Specifying where chrome driver needs to look!
Using Selenium you won't be able to initiate/spawn a new Browsing Context i.e. Chrome Browser session without the ChromeDriver.
The Parts and Pieces
As a minimum requirement, the WebDriver i.e the ChromeDriver talks to a browser through a driver and the communication is two way:
WebDriver passes commands to the browser through the driver
Receives information back via the same route.
Hence using ChromeDriver is a mandatory requirement.
As the documentation states, you can call webdriver.FirefoxProfile() with the optional argument of profile_directory to point to the directory of a specific profile you want the browser to use. I noticed it was taking a long time to run this command, so when I looked into the code, it looked like it was copying the specified profile Problem is, it takes an extremely long time for the profile to copy (something like >30 minutes, didn't have the patience to wait for it to finish.)
I'm using a hybrid of userscripts and selenium to do some automation for me, so to setup a new profile every single time I want to test out my code would be burdensome.
Is the only way to change this behaviour to edit the firefox_profile.py itself (if so, what would be the best way to go about it?)?
As per the current implementation of GeckoDriver with Firefox using the FirefoxProfile() works as follows :
If case of initiating a Browsing Session through a new Firefox Profile as follows :
from selenium import webdriver
myprofile = webdriver.FirefoxProfile()
driver = webdriver.Firefox(firefox_profile=myprofile, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get('https://www.google.co.in')
print("Page Title is : %s" %driver.title)
driver.quit()
A new rust_mozprofile gets created on the run as follows :
1521446301607 mozrunner::runner INFO Running command: "C:\\Program Files\\Mozilla Firefox\\firefox.exe" "-marionette" "-profile" "C:\\Users\\ATECHM~1\\AppData\\Local\\Temp\\rust_mozprofile.xFayqKkZrOB8"
Of-coarse on a successful closure (i.e. successful invocation of driver.quit()) the temporary rust_mozprofile.xFayqKkZrOB8 gets deleted/destroyed completely.
Again in case of initiating a Browsing Session through an existing Firefox Profile() as follows :
from selenium import webdriver
myprofile = webdriver.FirefoxProfile(r'C:\Users\AtechM_03\AppData\Roaming\Mozilla\Firefox\Profiles\moskcpdq.SeleniumTest')
driver = webdriver.Firefox(firefox_profile=myprofile, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get('https://www.google.co.in')
print("Page Title is : %s" %driver.title)
driver.quit()
Similarly a new rust_mozprofile gets created on the run as follows :
1521447102321 mozrunner::runner INFO Running command: "C:\\Program Files\\Mozilla Firefox\\firefox.exe" "-marionette" "-profile" "C:\\Users\\ATECHM~1\\AppData\\Local\\Temp\\rust_mozprofile.2oSwrQwQoby9"
Similarly in this case as well on a successful closure (i.e. successful invocation of driver.quit()) the temporary rust_mozprofile.2oSwrQwQoby9 gets deleted/destroyed completely.
So the timespan you are observing is the time needed for a FirefoxProfile() to scoop out a new rust_mozprofile.
Perhaps as per your question timespan for profile to copy (something like >30 minutes) is a pure overhead. So it won't be possible to use a Firefox Profile without making a copy of rust_mozprofile.
Solution
Upgrade Selenium Client to current levels Version 3.11.0.
Upgrade GeckoDriver to current GeckoDriver v0.20.0 level.
Upgrade Firefox version to Firefox Quantum v59.0.1 levels.
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
If your base Firefox base version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Firefox Quantum.
Execute your #Test.
Does anyone know how to force pyautogui or python in general to recognize a set screen size and take in display data, even if no display is connected?
I have a task that uses pyautogui, and selenium chrome driver, which both require a display, or they fail.
It runs on a server, so the start of the program requires my laptop to remote desktop into the server, allowing it to have a display, which allows launching a page with chromedriver, and pyautogui click components / screen search to work.
The issue arises that should my home network ever be down, it cannot kick off the remote desktop, and therefore my automation would fail.
My solution would be to emulate or force the program to behave as if a display existed, so it can just be run server side.
All of my servers are windows, so XVFB does not seem to be an option based on
Xvfb on Windows
Well I am using something similar on regular basis,
I am using Windows server to run my automated python script which uses selenium webdriver.
so, first your answer is you need to use code for screen size in the script and you can run that script with Windows task scheduler so, you don't have to touch your laptop or desktop to run remote desktop.
you can use chrome options if you are using chrome as headless browser.
I also, suggest if you are using server which is controlled by some third party who provides regular updates then, you can use chromedriver_autoinstaller package to take updated or supported version chrome driver according to your current version of chrome.
code:
import chromedriver_autoinstaller
from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from time import sleep
from selenium.webdriver.chrome.options import Options
chromedriver_autoinstaller.install()
#maximize the chrome
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--window-size=1920x1080")
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get('website address')
For automating task Windows task scheduler is the best option. you can refer this documentation or find something according to your need.
https://towardsdatascience.com/automate-your-python-scripts-with-task-scheduler-661d0a40b279
Note: If you just need to set screen size then your answer start here #maximize the chrome
You should emulate your display driver. Run:
xvfb-run --server-args="-screen 0 1024x768x24" python my_script.py
to launch your script instead of just python my_script.py.
I know the question has been a little while...
I just found out this using PyAutoGUI on remote machines or headless machines
at here https://github.com/asweigart/pyautogui/issues/133
Can look at this guys workaround: http://fredtantini.free.fr/blog/index.php?article58/automatiser-des-actions-avec-selenium-pyautogui-et-xvfb
Thank you
I have up and running an Apache Server with Python 3.x installed already on it. Right now I am trying to run ON the server a little python program (let's say filename.py). But this python program uses the webdriver for Chrome from Selenium. Also it uses sleep from time (but I think this comes by default, so I figure it won't be a problem)
from selenium import webdriver
When I code this program for the first time on my computer, not only I had to write the line of code above but also to manually download the webdriver for Chrome and paste it on /usr/local/bin. Here is the link to the file in case you wonder: Webdriver for Chorme
Anyway, I do not know what the equivalences are to configure this on my server. Do you have any idea how to do it? Or any concepts I could learn related to installing packages on an Apache Server?
Simple solution:
You don't need to install the driver in usr/local/bin. You can have the .exe anywhere and you can specify that with an executable path, see here for an example.
Solution for running on a server
If you have python installed on the server, ideally >3.4 which comes with pip as default. Then install ChromeDriver on a standalone server, follow the instructions here
Note that, Selenium always need an instance of a browser to control.
Luckily, there are browsers out there that aren't that heavy as the usual browsers you know. You don't have to open IE / Firefox / Chrome / Opera. You can use HtmlUnitDriver which controls HTMLUnit - a headless Java browser that does not have any UI. Or a PhantomJsDriver which drives PhantomJS - another headless browser running on WebKit.
Those headless browsers are much less memory-heavy, usually are faster (since they don't have to render anything), they don't require a graphical interface to be available for the computer they run at and are therefore easily usable server-side.
Sample code of headless setup
op = webdriver.ChromeOptions()
op.add_argument('headless')
driver = webdriver.Chrome(options=op)
It's also worth reading on running Selenium RC, see here on that.
I have a python webdriver script which successfully runs the test on the remote server using firefox, however it throws an error when using chrome and internet explorer.
I have added the directory with both drivers to the server's path. I have also tried starting the server using:
java -jar .\selenium-server-standalone-2.45.0.jar -Dwebdriver.ie.driver=.\IEDriverServer.exe -role hub
I consistently get the same error in powershell:
"... - Exception: The path to the driver executable must be set by the webdriver.chrome.driver system property;..."
Working Script:
def setUp(self):
self.wd = webdriver.Remote(
desired_capabilities=DesiredCapabilities.FIREFOX)
Throws Error:
def setUp(self):
self.wd = webdriver.Remote(
desired_capabilities=DesiredCapabilities.CHROME)
What is the culprit of this problem?
You have the Selenium driver for Firefox installed and configured, but not for Chrome. Installing and configuring boils down to this (source):
Setup
ChromeDriver is a separate executable that WebDriver uses to control
Chrome. It is maintained by the Chromium team with help from WebDriver
contributors. If you are unfamiliar with WebDriver, you should check
out their own Getting Started page.
Follow these steps to setup your tests for running with ChromeDriver:
Ensure Chromium/Google Chrome is installed in a recognized location
ChromeDriver expects you to have Chrome installed in the default
location for your platform. You can also force ChromeDriver to use a
custom location by setting a special capability.
Download the ChromeDriver binary for your platform under the downloads section of this site
Help WebDriver find the downloaded ChromeDriver executable
Any of these steps should do the trick:
include the ChromeDriver location in your PATH environment variable
(Java only) specify its location via the webdriver.chrome.driver system property (see sample below)
(Python only) include the path to ChromeDriver when instantiating webdriver.Chrome (see sample below)
So, basically, you need to either set the path to your Chrome drive in the PATH, or instantiate the drive like this:
driver = webdriver.Chrome('/path/to/chromedriver')
Download the Chromedriver
from selenium import webdriver
driver = webdriver.Chrome('C:\\Users\\xxx\\Downloads\\chromedriver_win32\\chromedriver.exe')
driver.get("http://www.seleniumhq.org/")
The code is for JAVA , set the path similarly in python
If the PATH is not set in your environment variable , then set it programmatically as below:
System.setProperty("webdriver.chrome.driver", "Path_to_your_chromedriver.exe");
driver = new ChromeDriver();
