I am trying to hide the CMD window that appears when launching PhantomJS with python:
from selenium import webdriver
browser = webdriver.PhantomJS()
There appears to be a solution when working with C#, however, I was not able to find anything similar for python. Since the feature for C# was added back in 2014, I assume something similar should exist for python too.
I'm using latest PhantomJS and Python 3.6.2.
This is how it looks like:
For me,
The below code works fine.
driver = webdriver.PhantomJS(
service_args=service_args,
desired_capabilities=caps,
executable_path='phantomjs.exe',
service_log_path=None
)
Here you have to add service_log_path=None for no log file that's why the console window will get hidden.
Still Not solved then
replace code from
(C:\Users\YOUR_USER_NAME\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\selenium\webdriver\common\service.py) file
self.process = subprocess.Popen(cmd, env=self.env, close_fds=platform.system() != 'Windows', stdout=self.log_file, stderr=self.log_file, stdin=PIPE)
to
self.process = subprocess.Popen(cmd, stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=False, creationflags=0x08000000)

I am using selenoid for remote browser testing in ruby.
In that I am using 'selenium-webdriver', 'capybara', 'rspec' for automation. And I am using attach_file method for uploading file to browser
I want to upload file on Firefox and Chrome browser but it raises error on both;
In chrome
Selenium::WebDriver::Error::UnknownCommandError: unknown command: unknown command: session/***8d32e045e3***/se/file
In firefox
unexpected token at 'HTTP method not allowed'
So After searching I found the solution for chrome which is to set w3c option false in caps['goog:chromeOptions'] > caps['goog:chromeOptions'] = {w3c: false}
So now chrome is using OSS bridge for handshaking but I don't know how to do it in Firefox. Similar solution is not available for Firefox.
My browser capabilities are following:
if ENV['BROWSER'] == 'firefox'
caps = Selenium::WebDriver::Remote::Capabilities.new
caps['browserName'] = 'firefox'
# caps['moz:firefoxOptions'] = {w3c: false} ## It is not working
else
caps = Selenium::WebDriver::Remote::Capabilities.new
caps["browserName"] = "chrome"
caps["version"] = "81.0"
caps['goog:chromeOptions'] = {w3c: false}
end
caps["enableVNC"] = true
caps["screenResolution"] = "1280x800"
caps['sessionTimeout'] = '15m'
Capybara.register_driver :selenium do |app|
Capybara::Selenium::Driver.new(app, browser: :remote,
:desired_capabilities => caps,
:url => ENV["REMOTE_URL"] || "http://*.*.*.*:4444/wd/hub"
)
end
Capybara.configure do |config|
config.default_driver = :selenium
end
I have found the problem. There is bug in selenium server which run on java so I have to change my selenium-webdriver gem version 3.142.7 and monkey-patch.
You can find more information here about the bug and resolution.
For now I have to change my gem and monkey patch the selenium-webdriver-3.142.7\lib\selenium\webdriver\remote\w3c\commands.rb file. check for below line which is on line no 150.
upload_file: [:post, 'session/:session_id/se/file']
and update it to
upload_file: [:post, 'session/:session_id/file']
i had a similar issue with rails 7. the issue is connected with the w3c standard. the core problem is that the webdriver for chrome uses a non-w3c standard url for handling file uploads. when uploading a file, the webdriver uses the /se/file url path to upload. this path is only supported by the selenium server. subsequently, the docker image provided by selenium works fine. yet, if we use chromedriver, the upload fails. more info.
we can solve this, by forcing the webdriver to use the standard-compliant url by overriding the :upload_file key in Selenium::WebDriver::Remote::Bridge::COMMANDS. since, the initialization of this the COMMANDS constant does not happen when the module is loaded, we can override the attach_file method to make sure the constant is set correctly. here the hacky code:
module Capybara::Node::Actions
alias_method :original_attach_file, :attach_file
def attach_file(*args, **kwargs)
implement_hacky_fix_for_file_uploads_with_chromedriver
original_attach_file(*args, **kwargs)
end
def implement_hacky_fix_for_file_uploads_with_chromedriver
return if #hacky_fix_implemented
original_verbose, $VERBOSE = $VERBOSE, nil # ignore warnings
cmds = Selenium::WebDriver::Remote::Bridge::COMMANDS.dup
cmds[:upload_file] = [:post, "session/:session_id/file"]
Selenium::WebDriver::Remote::Bridge.const_set(:COMMANDS, cmds)
$VERBOSE = original_verbose
#hacky_fix_implemented = true
end
end
In Firefox images we support /session/<id>/file API by adding Selenoid binary which emulates this API instead of Geckodriver (which does not implement it).
I had installed python 3.6 and selenium 3.5.2 version,geckodriver.exe . But when i used below code not able to open fire fox
from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
driver=webdriver.Firefox("C:\\Users\\Desktop\\Selenium\\seleniumfirefoxdriver\\geckodriver.exe")
driver.set_page_load_timeout(20)
driver.get("www.google.com")`enter code here`
driver.maximize_window()
driver.implicitly_wait(20)
Error shown as
NotADirectory Error:
[Win Error 267] The directory name is invalid: C:\\Users\\Desktop\\Selenium\\selenium firefoxdriver\\geckodriver.exe
Try below code-
driver = webdriver.Firefox(executable_path=r'C:\Users\Desktop\Selenium\seleniumfirefoxdriver\geckodriver.exe')
If there is a space in folder name 'selenium firefoxdriver', rename that folder to 'seleniumfirefoxdriver'
Try single slash and folder name doesn't contain space either use _ or remove space in folder name "selenium firefoxdriver". Make it "selenium_firefoxdriver" or "SeleniumFirefoxdriver".
and then use this code:
driver = webdriver.Firefox(executable_path=r'C:/Users/Desktop/Selenium/selenium_firefoxdriver/geckodriver.exe')
or
driver = webdriver.Firefox(executable_path=r'C:/Users/Desktop/Selenium/SeleniumFirefoxdriver/geckodriver.exe')
Trying to upgrade to Selenium 3.0 from Selenium 2.53. I can not put firefox in path, nor can put the gekodriver in path. I was using this in Selenium 2:
String firefoxLocation = System.getenv("ProgramFiles(X86)") + "\\Mozilla Firefox_42\\firefox.exe";
System.setProperty("webdriver.firefox.bin", firefoxLocation);
driver = new FirefoxDriver();
This worked perfectly. I upgraded to Selenium 3.0, installed firefox 49 and downloaded the latest geko. I now have this:
String firefoxLocation = System.getenv("ProgramFiles(X86)") + "\\Mozilla Firefox_49\\firefox.exe";
String gekoLocation = "..\\common\\geko\\gekodriver.exe";
System.setProperty("webdriver.firefox.bin", firefoxLocation);
System.setProperty("webdriver.firefox.marionette", gekoLocation);
driver = new FirefoxDriver();
Firefox opens to a blank window, then times out. I tried instead of setting webdriver.firefox.marionette, setting webdriver.geko.driver, but got the error that I must use "webdriver.geko.driver" (which I was using). How do I arrange it so I can specify a different firefox.exe location and a different gekodriver.exe location?
spelling wrong.
try this:
System.setProperty("webdriver.gecko.driver", gekoLocation);
use gecko instead of geko
I do not have privileges to change IE settings locally. I wrote a Java Code to change the capabilities of IEDriver using :
DesiredCapabilities caps = DesiredCapabilities.internetExplorer(); caps.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
caps.setCapability(
InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,
true);
I want to do the same thing while using the selenium webdriver in Robot Framework. I want to do something like this. But I do not know the right way to do it.
*** Keywords ***
Test Browser
${options}= Evaluate sys.modules['selenium.webdriver'].DesiredCapabilities.INTERNETEXPLORER sys,selenium.webdriver
Call Method ${options} add_argument INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS:True
Create WebDriver Internet Explorer ie_options=${options}
Open Browser To Login Page
Open Browser ${LOGIN URL} ${BROWSER}

Thanks a lot!
In the Selenium documentation for DesiredCapabilities, the configurable properties are listed. The required property is ignoreProtectedModeSettings which must be set to True
${dc} Evaluate sys.modules['selenium.webdriver'].DesiredCapabilities.INTERNETEXPLORER sys, selenium.webdriver
Set To Dictionary ${dc} ignoreProtectedModeSettings ${True}
Open Browser www.google.com ie desired_capabilitie=${dc}
${s2l}= Get Library Instance Selenium2Library
Log Dictionary ${s2l._current_browser().capabilities} # actual capabilities
For anyone that came here looking for a solution to this problem within Robot Framewor:
Set Chrome Desired Capabilities
[Documentation] Create the desired capabilities object with which to instantiate the Chrome browser.
${dc} Evaluate sys.modules['selenium.webdriver'].DesiredCapabilities.CHROME sys, selenium.webdriver
${experimental_options} Create Dictionary useAutomationExtension ${False}
Set To Dictionary ${dc} chromeOptions ${experimental_options}
Set Global Variable ${DESIRED_CAPABILITIES} ${dc}
As Pavol Travnik mentioned, David's answer no longer works. At some point the ignoreProtectedModeSettings key got placed inside the se:ieOptions dictionary within the capabilities dictionary. Here is code that will work with newer versions of the IEDriverServer:
${ie_dc} = Evaluate
... sys.modules['selenium.webdriver'].DesiredCapabilities.INTERNETEXPLORER
... sys, selenium.webdriver
${ieOptions} = Create Dictionary ignoreProtectedModeSettings=${True}
Set To Dictionary ${ie_dc} se:ieOptions ${ieOptions}
Open Browser ${url} ie desired_capabilities=${ie_dc}
You can see this if you debug Selenium's Python library, specifically webdriver/remote/webdriver.py and look at the response in start_session.
I am using the following code, as recommended here: Is there a way to use PhantomJS in Python?.
from selenium import webdriver
driver = webdriver.PhantomJS()
driver.set_window_size(1024, 768) # optional
driver.get('https://google.com/')
driver.save_screenshot('screen.png') # save a screenshot to disk
sbtn = driver.find_element_by_css_selector('button.gbqfba')
sbtn.click()
When I try to run it I get the following error:
WebDriverException - "Unable to start phantomjs with ghostdriver."
Apparently, this error can be solved by replacing the 3rd line with:
driver = webdriver.PhantomJS(executable_path='/usr/local/lib/node_modules/phantomjs/lib/phantom/bin/phantomjs')
I'm using Windows7, and the path for me appears to be: "C:\Users\myname\AppData\Roaming\npm\node_modules\phantomjs\bin\phantomjs". I have tried using this and variations of it as the executable_path, but I still get the same error. I have also tried adding the folder location to the path. Nothing has worked. I suspect that I am missing something pretty obvious.
Aha!
It was a slightly different location. The line I was looking for was:
driver = webdriver.PhantomJS(executable_path=r'C:\Users\myname\AppData\Roaming\npm\node_modules\phantomjs\lib\phantom\phantomjs')
