System.setProperty("webdriver.edge.driver","F:\\VW_MU_Util\\MicrosoftWebDriver.exe");
WebDriver driver = new EdgeDriver();
This is opening the edge browser however I cant go ahead since i'm getting error as:
org.openqa.selenium.remote.SessionNotFoundException: Unexpected error launching Internet Explorer. Protected Mode settings are not the same for all zones. Enable Protected Mode must be set to the same value (enabled or disabled) for all zones. (WARNING: The server did not provide any stacktrace information)
I tried to change the IE security settings but its opening the IE browser which i dont want to.
Make sure you have initiate correct Edge Driver, as according to your OS version.
Ref link : https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
Steps :
Trace Build version:
Download correct version of Driver:
Once it finished, Verify it with demo project without any project capabilities. If it run successfully on sample project, It might cause browser capability with Selenium Browser.

We recently upgraded our Windows 10 test environment with ChromeDriver v87.0.4280.20 and Chrome v87.0.4280.66 (Official Build) (64-bit) and after the up-gradation even the minimal program is producing this ERROR log:

Anyone facing the same? Was there any change in ChromeDriver/Chrome v87 with respect to ChromeDriver/Chrome v86?
Any clues will be helpful.
However these log messages can be supressed from appearing on the console through an easy hack i.e. by adding an argument through add_experimental_option() as follows:
options.add_experimental_option('excludeSwitches', ['enable-logging'])
Code Block:
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument("start-maximized")
# to supress the error messages/logs
options.add_experimental_option('excludeSwitches', ['enable-logging'])
driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get('https://www.google.com/')
My apologies for the log spam. If you aren't having issues connecting to a device with WebUSB you can ignore these warnings. They are triggered by Chrome attempting to read properties of USB devices that are currently suspended.
After going through quite a few discussions, documentations and Chromium issues here are the details related to the surfacing of the log message:
[9848:10684:1201/013233.169:ERROR:device_event_log_impl.cc(211)] [01:32:33.170] USB: usb_device_handle_win.cc:1020 Failed to read descriptor from node connection: A device attached to the system is not functioning. (0x1F)
Details
It all started with the reporting of chromium issue Remove WebUSB's dependency on libusb on Windows as:
For Linux (probably Mac as well), both WebUSB notification and communication works correctly (after allowing user access to the device in udev rules).
For Windows, it seems that libusb only works with a non-standard WinUsb driver (https://github.com/libusb/libusb/issues/255).
When the hardware is inserted and the VID/PID is unknown to the system, windows 10 correctly loads it's CDC driver for the CDC part and the WinUSB driver (version 10) for the WebUSB part (no red flags). However, it seems that chrome never finds the device until I manually force an older WinUSB driver (version 6 - probably modified also) on the interface.
The solution was implemented in a step-wise manner as follows:
Start supporting some transfers in the new Windows USB backend
Fix bulk/interrupt transfers in the new Windows USB backend
[usb] Read BOS descriptors from the hub driver on Windows
[usb] Collect all composite devices paths during enumeration on Windows
[usb] Remove out parameters in UsbServiceWin helper functions
[usb] Support composite devices in the new Windows backend
[usb] Detect USB functions as Windows enumerates them
[usb] Support composite devices with multiple functions
[usb] Hold interface requests until Windows enumerates functions
[usb] Add direction parameter to ClearHalt
[usb] Count references to a WINUSB_INTERFACE_HANDLE
[usb] Implement blocking operations in the Windows backend
These changes ensured that the new backend was ready to be tested and was available through Chrome Canary and chrome-dev-channel which you can access manually through:
chrome://flags#enable-new-usb-backend
More change requests were submitted as follows:
[usb] Mark calls to SetupDiGetDeviceProperty as potentially blocking: According to hang reports this function performs an RPC call which may take some time to complete. Mark calls with a base::ScopedBlockingCall so that the thread pool knows this task may be busy for a while.
variations: Enable NewUsbBackend in field trial testing config: This flag was experimental as beta-channel uses this change configuration as the default for testing.
As the experimental launch of the new backend appeared to be stable, finally these configuration was enabled by default so that the chanege rolls out to all users of Chrome 87 through usb: Enable new Windows USB backend by default. Revision / Commit
The idea was once this configuration becomes the default for a few milestones, Chromium Team will start removing the Windows-specific code from the old back-end and remove the flag.
Road Ahead
Chromium Team have already merged the revision/commit to Extend new-usb-backend flag expiration within Chrome v90 which will be available soon.
Update
As per #ReillyGrant's [Committer, WebDriver for Google Chrome] comment :
..." it would be good to reduce the log level for these messages so they don't appear on the console by default but we haven't landed code to do that yet"...

I encounered this problem yesterday,and I has fixed it by update all available windows update.

A partial solution that worked for me
I was getting this error too. It was stopping my program running.
I unplugged all my USB devices, ran the program, with no error.
Plugged the devices back in, ran the program. I am still getting the error, however, the program finished without the error stopping the program.
Note: For WebdriverIO on Windows 10, this suppresses the error messages for me:
"goog:chromeOptions": { "excludeSwitches": ["enable-logging"] }
I want to run a simple test using OxygenHQ, of opening wikipedia and then search for hello world. The script written is working fine for Chrome and Firefox but in case of IE mutiple windows are opening without the page and then it fails eventually.
Is there any way to fix this? I went through the docs provided at http://docs.oxygenhq.org/guide-web-intro.html but could not get a concrete answer on why this is only happening for IE. Here is a console output and screenshot for reference.
Console Output :
Initializing...

UNKNOWN_ERROR - undefined: args[0].endsWith is not a function at line 1Test finished with status --> FAILED

This might be connected to your internet settings
make sure that the IE screen size is 100%
make sure all Internet options in Security Tab (Internet, Local Internet etc') are either with the Enable protected mode on or off (should be the same for all)
see picture
Have a look again at the Oxygen web site, it has had a major facelift and a lot of new content
I want to open an application website on Firefox browser using Selenium Webdriver as a different user.
Currently, I am using gecko driver to open that application link, it successfully opens up the browser but unable to open the application link.
But I am able to achieve the same manually by going to Mozilla Firefox icon and clicking on
"Run as different user"
option (as shown in below image) which further open a popup for user credentials and by entering Username and Password of different user there I am able to open the application link in browser.
So, is there any way that I can achieve same process using Selenium Webdriver and opens up my application link.
Thanks in Advance!!
You should rather create Firefox profile by running firefox.exe -p to launch profile manager. Then you can instantiate firefox web driver implementation and configure it to use given profile.
Are you sure that you want to use pre-configured profile? I find much easier to manage to run drivers in private/incognito mode and set cookies manually to configure tests.
You might provide firefox_binary as a parameter for the webdriver:
http://selenium-python.readthedocs.io/api.html
firefox_binary – Instance of FirefoxBinary or full path to the Firefox
binary. If undefined, the system default Firefox installation will be used.
...so, you might use a wrapper script to run firefox as the different user (use sudo in Linux).
I am using Firefox 55.0.2 (64-bit) with selenium. The code works fine, however I see an icon in Firefox saying Browser is under remote control and the URL is highlighted in orange as shown in below screen shot.
Is there a way to disable this message in Firefox?
You wouldn't get that in the previous versions of firefox (version 45 or below). Its just an update and cannot be disabled. Even google chrome shows a message(chrome is autmated by a software). or you could just use the previous versions of the browser.
Maybe not related directly to selenium use,
But in case of getting stuck in "under remote control" after having launched firefox with a kind of:
firefox -marionette -foreground -no-remote -profile /path/to/existing/profile
It's because this way it toggles marionette:true in about:config,
Thanks to Firefox Stuck in Remote Control Mode for pointing to this marionette config entry
I've come upon a strange issue while setting up a Selenium Grid. My RemoteWebDriver works once, and then throws a NoSuchWindowException if I try to do anything else with it.
For example, if I run the following test (which I wrote just to explore this problem):
#Test
public void testStuff() {
try{Thread.sleep(2000);}catch(Exception e){}
driver.get("http://www.google.com");
try{Thread.sleep(2000);}catch(Exception e){}
driver.get("http://www.stackoverflow.com");
System.out.println(driver.getTitle());
}
An IE browser pops up on the virtual machine that I'm sending it to. That browser then successfully goes to google. However, when I try to do anything else with it (like go to another website, or get the window's title), I get the following exception:
org.openqa.selenium.NoSuchWindowException: Unable to get browser(WARNING: The server did not provide any stacktrace information)
I have tried all sorts of combinations, with the same result every time: I can successfully call a method off of the RemoteWebDriver once, but the second time it throws this exception.
Does anyone have any ideas what might be causing it?
Things I've checked:
The IEDriverServer and the VM are both 64-bit.
The console for both the Hub and the Node yield no useful clues. The Node console contains:
INFO - Executing: [get: http://www.google.com] at URL: /session/de0a7b62-33a1-4330-b9a9-25b99f5504-cf/url)

WARN - Exception thrown

In response to Richard's comment, the WebDriver really is quitting at then end of the test. I'm printing out the following in the console:
successfully strt RemoteWebDriver: internet explorer on WINDOWS (40b01604-9217-4f67-b809-61cd90d23c84)
preparing to quit RemoteWebDriver: internet explorer on WINDOWS (40b01604-9217-4f67-b809-61cd90d23c84)
successfully quit RemoteWebDriver: internet explorer on WINDOWS (null)
Also, in the Task Manager on the VM, the "IEDriverServer" process goes away at the end of the test. But the weird thing is, The browser itself does not close. I have no idea what could be causing that, and whether or not it is related.
That sounds to me as beeing a typical problem with the IEDriverServer.exe, occurring if configuration on a node machine isn't done properly.
Be shure to follow all requirements described on Selenium Website. Corresponding part cited here:
Required Configuration
The IEDriverServer exectuable must be downloaded and placed in your PATH.
On IE 7 or higher on Windows Vista or Windows 7, you must set the Protected Mode settings for each zone to be the same value. The value can be on or off, as long as it is the same for every zone. To set the Protected Mode settings, choose "Internet Options..." from the Tools menu, and click on the Security tab. For each zone, there will be a check box at the bottom of the tab labeled "Enable Protected Mode".
Additionally, "Enhanced Protected Mode" must be disabled for IE 10 and higher. This option is found in the Advanced tab of the Internet Options dialog.
The browser zoom level must be set to 100% so that the native mouse events can be set to the correct coordinates.
For IE 11 only, you will need to set a registry entry on the target computer so that the driver can maintain a connection to the instance of Internet Explorer it creates. For 32-bit Windows installations, the key you must examine in the registry editor is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. For 64-bit Windows installations, the key is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. Please note that the FEATURE_BFCACHE subkey may or may not be present, and should be created if it is not present. Important: Inside this key, create a DWORD value named iexplore.exe with the value of 0.
I had the same issue and was able to solve it with these hints.
