seleniumAddress not taking effect in Protractor config - selenium

I am having a issue where seleniumAddress is not taking effect in protractor config. I use seleniumAddress: 'http://127.0.0.1:4444/wd/hub' but I see:
[18:52:35] E/launcher - Timed out waiting for the WebDriver server at http://127.0.0.1:47780/hub
The port should be 4444 instead of 47780. Any ideas?

Selenium with Firefox-ESR in Alpine Docker image

I'm using Selenium for testing from Java code, it's started automatically with maven, when I run mvn verify it uses gecko-driver to start new firefox instance for selenium:
final FirefoxOptions opts = new FirefoxOptions();
if (HEADLESS_MODE) {
opts.addArguments(ARG_HEADLESS);
}
return new FirefoxDriver(opts);
It's working fine on my machine (and on machines of other developers) in both modes "headless" and normal. Now I'm trying to run Selenium tests with CI builds in Alpine Linux Docker container. When I tried to run it as-is, I've got an error:
mozrunner::runner INFO Running command: "/usr/bin/firefox"
"-marionette" "--headless" "-foreground" "-no-remote"
"-profile" "/tmp/rust_mozprofile.pW1sbkcv98QN"
Error: GDK_BACKEND does not match available displays.
Then I installed all suggested tools (dbus and xvfb) from this post and started it before running tests:
apk add xvfb dbus
dbus-uuidgen > /etc/machine-id
export DISPLAY=:99
Xvfb $DISPLAY -ac &
mvn verify
but now Selenium tests are hadning for about 10 seconds and failing with error

It seems I'm doing something wrong here, what is the correct way to run headless Selenium tests in Alpine Linux Docker container? I'd prefer to configure existing Docker image instead of using Selenium images, because the migration will be expensive.
Update:
Selenium version is 3.141.59
Gecko-driver version is v0.24.0-linux64
Firefox-ESR version is: 52.8.1-r0
Update2:
xvfb, dbus and exported DISPLAY are not actually needed to run Firefox in headless mode - just run firefox --headless and it's all.
As per Mozilla --headless flag is not supported in Firefox 52-esr.Headless flag was introduced in version 55 (for Linux) and 56 (Mac/Windows) . Please try on latest Firefox ESR release.

selenium server standalone: unable to create a new session with vagrant in headless mode

I am trying to run the selenium server standalone in a vagrant box, with the following command:
java -jar selenium-server-standalone-3.13.0.jar
When I click the 'create session' button at http://lab.local:4444/wd/hub/static/resource/hub.html from my host web browser. I get a unable to create a new session error message.
I ask to create a firefox browser session for which I get the driver located in /usr/local/bin/geckodriver.
Firefox has been installed on the vagrant box with sudo apt install firefox-esr.

When I run the same executable directly from my host, I get no error and the firefox session is created with success.
I try to run a X server, Xvfb as follow but this does not change anything:
Xvfb :1 -screen 0 1600x1200x16 &
export DISPLAY=:1
java -jar selenium-server-standalone-3.13.0.jar
Problem solved after switching to selenium-server-standalone-3.3.1.jar with geckodriver 0.14.0. Sessions are created with success with this configuration.

Codeception - Can't connect to Webdriver (Acceptance Test)

I can access url and create sessions:
http://localhost:4444/wd/hub/static/resource/hub.html
but when i execute ./codecept run i get an error, but i have Selenium Server running:
[ConnectionException] Can't connect to Webdriver at http://127.0.0.1:4444/wd/hub. Please make sure that Selenium Server or PhantomJS is running.
To execute Selenium Server, i used this command:
java -Dwebdriver.gecko.driver=./geckodriver -jar "selenium-server-standalone-3.12.0.jar"
I tried too with IE and Chrome (i have the same problem too):
java -Dwebdriver.chrome.driver=./chromedriver -jar "selenium-server-standalone-3.12.0.jar"
java -Dwebdriver.ie.driver=./IEDriverServer -jar "selenium-server-standalone-3.12.0.jar"

As per the documentation at codeception.com the acceptance.suite.yml should have been as follows :

browser: firefox

Problem fixed. I was using proxy.
For future users with same problem like me, can follow the steps.
First, check if you have proxy defined with this command:
echo %http_proxy%
If return some result, you need set a empty proxy with this command:
set http_proxy=
You need define a proxy always you are opening a new command line.

e2e tests fail on server with selenium

I'm about to create an application full js based on vuejs. Following https://github.com/vuejs-templates/webpack, I have started a project:
$ vue init webpack my-project && cd my-project && yarn install
When I run unittest yarn run unit everything goes well, but when I run yarn run e2e which runs nightwatch.js, I get this error:
> Starting dev server...
Starting to optimize CSS...
> Listening at http://localhost:8889

The selenium server is started on the fly when the e2e tests start and is shutdown when they finish. I'm sure because when I stop nightwatch.js before it fails I see :
$ ps aux | grep -i selenium
java -Dwebdriver.chrome.driver=node_modules/chromedriver/lib/chromedriver/chromedriver -jar node_modules/selenium-server/lib/runner/selenium-server-standalone-2.53.1.jar -port 4444
So the real error based on the output I get is mostlikely Error retrieving a new session from the selenium server. How do I fix this?
package.json

"cross-spawn": "^5.0.1",
"nightwatch": "^0.9.12",
"selenium-server": "^2.53.1",

require('babel-register')
var config = require('../../config')

module.exports = {

}
},
I recently started a Vue.js project with Webpack template. Your problem sounds familiar, but surprisingly, I forgot how I solved it...
The only difference I can see between your package.json and mine is the selenium-server version (^3.0.1). You should also check your Node version because Nightwatch is based on it. I remember that I had to update Node and npm for some reason (I do not use Yarn).
This is my environment (and it is working fine):
Node.js (v8.1.3)
npm (5.0.3)
Did you run node nightwatch.config.js, or node {whatever your nightwatch config file is called}. This will install Selenium and ChromeDriver correctly.

NightWatch Selenium Socket Hangup in Jenkins / Ubuntu16

Issue :
We are running NightWatch tests in Jenkins, and once in a while, we get this error :
[0;31mConnection refused! Is selenium server started?
[0m[0;90m{ Error: socket hang up
at createHangUpError (_http_client.js:253:15)
at Socket.socketCloseListener (_http_client.js:285:23)

at TCP._handle.close [as _onclose] (net.js:501:12) code: 'ECONNRESET' }[0m
The fix recommended in other places is already there :
export DBUS_SESSION_BUS_ADDRESS=/dev/null
This is how we run the tests :
sudo npm install selenium-standalone -g
selenium-standalone install --version=3.0.1 --baseURL=https://selenium-release.storage.googleapis.com --drivers.chrome.version=2.28 --drivers.chrome.baseURL=https://chromedriver.storage.googleapis.com --basePath=bin
sudo npm install nightwatch#0.9.13 -g && nightwatch --tag sanity --retries 1 --suiteRetries 1
Rebuilding the job usually run the tests successfully.
Softwares' version:
Chrome : 57
Chrome driver : 2.28
Selenium: 3.0.1
NightWatch : 0.9.13 (bumped down from 0.9.14 in case the latest release had a bug but no change.)
Jenkins : 1.6x
Ubuntu : 16.04
Using xvfb
Error Scenarios
The tests were running fine until about 2 weeks ago, just when we switched to Ubuntu 16, but that day it started happening on Ubuntu 14 too.
It especially happens when we've just spun a new Jenkins slave (on AWS cloud.) Happens more often at the very start of the test run but sometimes it happens in the middle of the run too.
I'll appreciate any help or pointers!
I have the same problem yesterday.
Maybe you can change the version of Chrome.
such as Chrome:55.

We ran into a similar issue, but our error message was more specific:
Selenium is already running on port ####. Or some other service is.
The solution was to use the Jenkins Port Allocator Plugin to assign an available port number to an environment variable.
From there, we were able to set the port number in our globals.js like this (with a default of 4444 for running locally):
portNumber: process.env.PORT_NUMBER || 4444,
In our nightwatch.conf.js file, we used a lodash template to replace values in our nightwatch.json like this:
fs = require('fs'),
_ = require('lodash'),
template = _.template(fs.readFileSync('./nightwatch.json', 'utf8')),
settingsString,
settings;
settingsString = template({
portNumber: globals.portNumber
});
settings = JSON.parse(settingsString);
module.exports = settings;
Finally, in our nightwatch.conf file, we set the values for all port references to:
"<%= portNumber %>"
