I started two chrome using
start chrome --remote-debugging-port=9222
start chrome --remote-debugging-port=9223
I tried connecting to these browsers using rpaframework keyword:
RPA.Browser.Selenium.Attach Chrome Browser 9222 alias=site1
RPA.Browser.Selenium.Go To https://google.com
RPA.Browser.Selenium.Attach Chrome Browser 9223 alias=site2
RPA.Browser.Selenium.Go To https://duckduckgo.com
But this is not working, first one is getting connected but the second one is waiting for sometime and then shows error
failed with: WebDriverException: Message: unknown error: cannot
connect to chrome at localhost:9222 from chrome not reachable

You can use Selenium Grid.
Create a Hub:
java -jar sel.jar -role hub -port 9000
Create as many Node you need.
You can run chrome on each node:
java -Dwebdriver.gecko.driver="/driver/geckodriver" -sel.jar -role webdriver -hub http://localhost:9000/grid/register -port 9001
java -Dwebdriver.gecko.driver="/driver/geckodriver" -sel.jar -role webdriver -hub http://localhost:9000/grid/register -port 9002
You can check the nodes using below:
http://localhost:9000/grid/console

I am trying to launch browser with a url that could record audio and video. using test cafe. After launching, I see a an Application error, A client side exception has occurred. Below is my code.
Browser Console Message
My arguements to run the test -
yarn run testcafe --hostname chrome e2e\launchwebSDK.js --live --use-fake-ui-for-media-stream --use-fake-device-for-media-stream
It's likely that this problem occurs because Chrome doesn't allow calling the getUserMedia API from insecure origins. I recommend you specify localhost as a hostname or enable https mode to bypass this limitation:
testcafe --hostname localhost ...
or
testcafe --ssl pfx=/path/to/cert.pfx ...
I try to remotely debug tests run by Internjs.
Basically it is a Chrome that is run by Selenium and Chromedriver.
I set up Chromedriver debuggerAddress option as
debuggerAddress: '127.0.0.1:8765'
Now when I run tests Selenium waits some time and than fails with message:
FATAL ERROR
UnknownError: [POST http://localhost:4444/wd/hub/session / {"desiredCapabilities":{"browserName":"chrome","name":"tests/intern_local","idle-timeout":60,"selenium-version":"2.44.0","chromeOptions":{"debuggerAddress":"127.0.0.1:8765"}}}] unknown error: cannot connect to chrome at 127.0.0.1:8765
from chrome not reachable
(Driver info: chromedriver=2.12.301326 (093c7e07b4a916b690e784b0374c7f618f1ea4be),platform=Mac OS X 10.10.1 x86_64) (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 60.64 seconds
I'm not sure what I have to do so that chrome would connect to server.
I did try:
Running chromedriver on that port ./chromedriver_2.11 --port=8765
Running chrome with --remote-debugging-port=8765
But I have no other ideas how to start a chrome debug server.
Useful links that I did try that that did not work for me:
Remote debugging protocol
Remotely debugging Chrome Desktop
Chromedriver Capabilities (aka ChromeOptions)
Update 1 Forcing Chromedriver to use a Chrome instance with remote debugging on
Run a new Chrome instance as in Mozilla article
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222 --no-first-run --no-default-browser-check --user-data-dir=$(mktemp -d -t 'chrome-remote_data_dir')
In intern set
intern.capabilities = {
'selenium-version': '2.44.0'
, 'chromeOptions': {
debuggerAddress: '127.0.0.1:9222'
}
};
Now when you run Intern tests Intern will use your previously open Chrome instance. Now you can open localhost:9222 and you'll see that you can debug that tab in which tests run. However for me I'm just able to see that remote tab, but clicking on it does nothing.
I also tried Firefox WebIDE. I tried to connect to localhost:9222, it starts to load and after some time it says that it can't connect.
I tried something similar this evening, without using a framework. I opened a webdriver session & added the remote debugger capabilities.
It seems that it is not possible to run a webdriver session & remote debug at the same time. I asked some Google guys to verify that, but haven't received an answer yet.
I am launching chrome browser using
selenium = new DefaultSelenium("localhost", 4444, "*googlechrome",
"https://example.com/");
But i get a popup with following message and it freezes:
An administrator has installed Google Chrome on this system, and it is available for all users. The system-level Google Chrome will replace your user-level installation now.
Console Log till point of freeze:
Server started

Any suggestions?
Try giving location of your chrome exe too along with browser name like this :
selenium=new DefaultSelenium("localhost", 4444, "*googlechrome C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe", "https://example.com");
I'm trying to start the google-chrome browser in disabled web security mode. The selenium log says:
15:36:33.526 INFO - Command request: getNewBrowserSession[*googlechrome, http://www.myurl.de, , commandLineFlags=--disable-web-security] on session null
Anyways, it just hangs after

Here's the stack trace:

Selenium is started by robotframework by the robotframework-maven-plugin. Also xvfb is started by the maven build script to simulate a display. But the startup configuration does not seem to be the problem. Everything starts fine, just the browser won't get up.
I hope anyone can help me.
Make sure that the user account that is launching the browser has a home directory. Otherwise the browser profile creation will fail.
I'm running Selenium RC server 2.0b3 on Ubuntu 11.04. I installed Google Chrome and am trying to run some tests against it. I'm able to run tests against Firefox just fine. However, when I run my test against the Selenium server, it just hangs and then times out. This is all the server log reports (notice the null session):

Any ideas how I can eliminate the Google Chrome null sessions and get my tests to run? Thanks, - Dave
You're running into Chrome's security restrictions. You need to set the "mode" value to "disableSecurity" in your BrowserConfigurationOptions to disable them.
