2016-10-13: ChromeDriver v2.24 has been released which supports Chrome v52-54. (Thanks #Anton)
2016-08-16: One of the recent updates to the Chrome Dev channel introduced a bug preventing ChromeDriver from properly starting. Having just worked around the same problem, I would suggest backing up your data and reverting to the Beta or Stable release channel of Chrome. See the Chrome Release Channels for more details on safely switching.
Alternatively, switching to the Dev version of ChromeDriver should also fix the issue. From a closed issue on the chromedriver project:
There are some Devtool changes in Chrome dev channel v54 which is not currently supported in Chromedriver stable v2.23.
You may want to use dev version of Chromedriver which has the fix. It can be downloaded from chromedriver…/continuous/….zip
Review the issue for the full link.
If the latest protractor is not having the latest chromedriver then to update it using webdriver-manager follow these below steps
enter latest chromedriver version in file config.json this file is present under path /node_modules/protractor/node_modules/webdriver-manager/built
optional (and change 'mac32' to 'mac64' in file 'chrome_driver.js' which is present under path /webdriver-manager/built/lib/binaries)
run webdriver-manager update in the console.
hint: To get the path of 'webdriver-manager' folder observe the console after command webdriver-manager update
Since I got the same issue and found this question, I'd like to add a bit more context: it is indeed a version problem between an 'old' chrome driver (2.22 in my case) and a 'newer' chrome release (54 in my case) like Sean answered.
However there is no need to fiddle manually with config files or downloads.
Instead just run
npm update protractor -g
To update protractor globally then
webdriver-manager update
To update the chrome driver. The newer chrome driver v2.25 is not yet included in the protractor package at the time of writing (you will get v2.24 instead) but it works fine with Chrome 54. Protractor is v4.09 at the time of writing. The same trick should work for future versions too!
After big battle with above issue i have found the solution for it. So please
don`t do anything.
First of all uninstall your chrome browser and reinstall it. That`s it protractor will not throw any such errors.
I even don`t know why this happened and for what reasons looks bit strange but yes the only solution is uninstall the chrome browser and reinstall it.
npm uninstall webdriver-manager -g
npm install webdriver-manager -g
I have the same problem with 2.24 version. In order to fix this bug download chromedriver.exe with version 2.25, it's available now by link https://sites.google.com/a/chromium.org/chromedriver/downloads
Try to reinstall webdriver-manager
npm uninstall webdriver-manager -g
npm install webdriver-manager -g
Issue was fixed for me after I installed webdriver-manager: 10.2.8
This is common issue, I faced it many times.
I use chromedriver in my selenium framework once in month and I usually get this type of error.
Follow below steps:
Unistall/Remove all existing chromedriver.
Install latest
chromedriver from official google site.
Set system path to chromedriver.exe folder (So you don't need to bother about setting the system path from code)
Restart the IDE (If already running)
ENJOY !
I updated to Chrome Driver 2.25 which fixed the problem for me. This is a simple update:
Download the latest version from: https://sites.google.com/a/chromium.org/chromedriver/downloads
Unzip the contents (it's one file "chromedriver.exe").
Copy that over your existing chromedriver.exe
For me that was at: \node_modules\protractor\selenium
That's it. I reran the tests and the pesky error went away.
First of all uninstall your chrome browser and reinstall it. That`s it protractor will not throw any such errors.
I even don`t know why this happened and for what reasons looks bit strange but yes the only solution is uninstall the chrome browser and reinstall it.
npm uninstall webdriver-manager -g npm install webdriver-manager -g

I was using chromedriver ver. 75.0.3770.8 however Chrome browser was updated by then and now I need to install chromedriver a least 77.0. I did so, I exchange chromedriver.exe file in the folder where the previous but it didn't work, Still there was error code 199 -> that available verison of chromedriver is 75. Then I used webdriver-manager update --versions.chrome 77.0.3865.40 and wbedriver-status command says that I have twoe versions of chromedriver:
I/status - chromedriver versions available: 76.0.3809.12, 77.0.3865.40 [last]
But when I attempt to run test it only seems to see 75 verison and error 199 still occurs. I've added Path Env. Variable as on this video:
https://youtu.be/dz59GsdvUF8?t=51
Any ideas how to remove the older verison 75?
protractor can be download/setup as global and local as per your npm command.
Check if your deleting from local and script pointing to global npm package of protractor or vice versa
I am trying to start my selenium server from intelliJ and it is saying the file is corrupt.
I use intelliJ to run my protractor tests, and when I starts the selenium server from the intelliJ terminal before I run them. For whatever reason it is saying my jar file for selenium-server-standalone is coming back as corrupt. Is there a way to fix this and, if not, is there a way to delete and then reinstall selenium server?

[11:39:09] I/start - Selenium Standalone has exited with code 1
As you can see, it is just exiting after it comes back as corrupt. I haven't had issues with this before. I did try to update the webdriver.
I found a workaround, which may or may not be acceptable. You can force webdriver-manager to use an older version of the selenium-standalone package. This avoids whatever the problem is with 4.0.0-alpha-1.
$ webdriver-manager clean
$ webdriver-manager update --standalone --versions.standalone=3.8.0
$ webdriver-manager start --versions.standalone=3.8.0
…

2019-04-24 14:19:55.483:INFO::main: Logging initialized #390ms to org.seleniumhq.jetty9.util.log.StdErrLog
There is an open defect in the webdriver-manager project for this issue: https://github.com/angular/webdriver-manager/issues/370
As a temporary workaround you can use the directConnect attribute in your protractor config.
There is issue with 4.0.0-alpha-1 , after deleting files you can install some older versions that will work. If you will just update wevdriver manager by using webdriver-manager update then it will not work for you but you need to use something like " webdriver-manager update --standalone --versions.standalone="some older version"
Since you are using Protractor, you can try a webdriver-manager update
You should be starting the server like this - webdriver-manager start
I believe Protractor's webdriver-manager already contains the selenium standalone server.
Or you can just add this line in your conf file, and you will no longer need to manually start anything before running a Protractor spec file directConnect: true
I use protractor to test Angular2 app. It was working fine and I think I didn't change nothing in conf but now it ends up with this:

I work on a Mac OSX 10.11.4, Chrome 54.0.2840.71.
Any suggestion? Thanks
--- EDIT 26/10
Since it depends on each one settings it looks like theres no absolute answer to this. The main idea is to update protractor/ chromedriver / webdriver-manager accordingly.
Saying that i now face another problem : every basic test i do, including ( for instance ) a browser.get() is failing with :
Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL
I don't know if it's an isolated case and if it fits here (I use jasmine2 as framework) so I start another question here
I installed ChromeDriver v2.24 and stored it in: /usr/local/Cellar/chromedriver/2.24/bin and it fixed the error for me.
As mentioned by others, looks like it is a problem with the chromedriver installed in the system with the new version of chrome. For mac, I updated the chromedriver using 'chromedriver-update' and this fixed it.
I had a similar problem and solver it by forcing chromedriver 2.24 to install by manually removing webdriver-manager
delete the folder rm -rf /usr/local/lib/node_modules/webdriver-manager/
reinstall webdriver
npm install -g webdriver-manager
I updated the selenium-standalone to the latest version 5.8.0 (from 5.1.0). It will install the newer version of chrome webdriver(2.25), instead of install chrome driver2.21. This solved the issue on my end.(no connection, session exception)
If even after updating the webdriver to 2.25, the error is still occurring and if you are using the terminal app this should help :
I managed to fix the issue by unchecking “Set locale environment variables on startup” checkbox in advanced terminal app settings.
Or try to launch your test with this prefix :
LC_NUMERIC=”en_US.UTF-8″ npm test
I'm trying to run protractor by connecting directly to Chrome, not running Selenium. As the docs say, this is possible by setting the directConnect to true in the config file.
When I run protractor with directConnect: true, I get:
Using ChromeDriver directly...
[launcher] Running 1 instances of
WebDriver Error: spawn ENOENT
at errnoException (child_process.js:1001:11)
at Process.ChildProcess._handle.onexit (child_process.js:792:34) [launcher] Process exited with error code 1
If I run protractor without directConnect and instead specify my selenium url, everything runs fine.
I'm running Protractor version 1.6.1, Chrome version 41.0.2272.35 beta-m (64-bit), and Chromedriver version 2.13.0.
Update: While the solution below worked for me, after talking with a protractor dev I realized that if I run webdriver-manager update to install a local chromedriver, then I don't need to set the chromeDriver setting in my protractor config.
I had the same issue and solved it by varying the chromeDriver path setting in protractor-conf.js depending on whether I was on Windows or OSX/Linux.
Solution and writeup below assumes you are using chromedriver provided by npm install chromedriver. Also this solution worked with protractor 3.2.2 and chromedriver 2.21.2.
Protractor+chromedriver worked on OSX and Linux but I was getting ENOENT errors on Windows. I have filed an issue here and have also documented a workaround.
The issue (I think) is that childProcess.spawn has issues on Windows (see a list of issues here) and the node_modules/chromedriver/bin/chromedriver file will not correctly run when called via childProcess.spawn - likely because this file is not executable and Windows doesn't know to use the node binary to interpret the file.
The workaround is to provide the path to the windows executable when running on Windows. It is easy enough - though hackish - to vary the chromeDriver arg in protractor-conf.js as demonstrated below :
protractor-conf.js for all three OS:
var chromeDriverPath = process.platform === 'win32' ? 'node_modules/chromedriver/lib/chromedriver/chromedriver.exe' : 'node_modules/chromedriver/bin/chromedriver';
exports.config = {
directConnect: true,
chromeDriver: chromeDriverPath,
specs: [
'features/*.feature'
],
capabilities: {
browserName: 'chrome',
platform: 'ANY',
chromeOptions: {
args: ['--test-type']
}
}
}
Hope this helps.
ENOENT means Error, NO such ENTity, and relates to the file system.
Check you have the right path set in the chromeDriver option.
capabilities : {
chromeOptions: {
"debuggerAddress":"127.0.0.1:8088"
}
},
directConnect: true,
chromeDriver : "../bin/chromedriver_2.15.322448.exe"
I'm trying to learn AngularJS. As part of this, I want to learn to use end-to-end testing. Currently, I have a directory structure like this:

},
specs: [
'../src/tests/test.e2e.js'
],
jasmineNodeOpts: {
showColors: true,
defaultTimeoutInterval: 30000
}
};
test.e2e.js looks like the following:
'use strict';

driver = protractor.getInstance();
beforeEach(function () {
driver.get('#/');
});
it('My First Test', function () {
message = "Hello.";
expect(message).toEqual('World.');
});
});
When I attempt to run my end-to-end tests using protractor, I run the following command from the command-line:

What am I doing wrong?
I solved this with --standalone flag:
webdriver-manager start --standalone
I got it working by removing the following line from my config.js
seleniumAddress: 'http://localhost:4444/wd/hub',
Are you running a selenium server? The git README states the following:
WebdriverJS does not natively include the selenium server - you must start a standalone selenium server. All you need is the latest selenium-server-standalone.
source: https://github.com/angular/protractor
The error message is due to the following:
[ECONNREFUSED] The attempt to connect was ignored (because the target is not listening for connections) or explicitly rejected.
Check the URL of the Webdriver manager. The default URL is:
http://localhost:4444/wd/hub
Use a background process to run the webdriver-manager, then run protractor:
Start-Process webdriver-manager start -passthru
protractor conf.js
This will start up a Selenium Server and will output a bunch of info logs. Your Protractor test will send requests to this server to control a local browser. Leave this server running

For me, this had happened due to incompatible versions of Node and Protractor.
My fix-
Update Node to latest version (v7.0.0 in my case)
Follow steps given here https://stackoverflow.com/a/19333717/1902831
Install latest protractor version (4.0.10 in my case) using:
npm install -g protractor
Open another terminal and execute these command:
webdriver-manager update
webdriver-manager start
Run tests in another terminal using:
protractor conf.js
If you are using the npm protractor-webdriver grunt plugin (https://www.npmjs.org/package/grunt-protractor-webdriver) you may exeprience same kind of error.
This is due to webdriver termination just before test ends. The test runs successfully and then you have a message like :
Session deleted: Going to shut down the Selenium server

I resolve this using the keepAlive option in the grunt plugin.
Here is my Gruntfile.js config :
protractor_webdriver: {
options: {
keepAlive : true // True to keep the webdriver alive
},
start: {
},
},
...
I hope this will help someone.
JM.
I also faced the same problem,the trick that worked for me is to use two cmd windows,keeping the one open after typing webdriver-manager start and without pressing enter key(if enter key is pressed the selenium server is shutdown,don't know why) open another cmd window and call your tests.
#Alexandros Spyropoulos, it took me quite some time to figure out how to run protractor and I think we had the same problem. You should open one terminal tab and run webdriver-manager start --standalone. Then open another terminal tag and run protractor ***.conf.js
In the hopes that it might help someone: I'd been having the same problem - encountering ECONNREFUSED using grunt-protractor-runner. The nuance to my case is that I was running my entire E2E environment (test files, web application and entire backend) within a Docker container.
I tried running protractor
with and without additional grunt-protractor-webdriver task to get webdriver up and running 'manually' (no difference);
with and without enabling directConnect and keepAlive settings (bypassing Selenium and resulting in crashes related to Chromedriver, one of which was described here).
The solution was rather simple: increase the amount of memory allocated to the container. On my Windows 10 host machine, I performed the following steps:
Run VBoxManage.exe modifyvm default --memory 8192 (via custom shell script) before starting the docker-machine (via Docker Quickstart script, which is equivalent to docker-machine start). (Thanks to this SO answer).
Changing my shell script to run my default container, adding the --shm-size=4G argument to my docker run command. (See docs)
You can verify if it worked by running df -h in your guest machine, by checking the amount of memory mounted on /dev/shm.
As a result, I no longer have seemingly inexplicable errors such as ECONNREFUSED.
If you run the provided protractor demo, you should try running the protractor config in the same command prompt as selenium. Try running both selenium server and protractor separately.
Make Sure first selenium runs by following command.
webdriver-manager start --standalone
And run the protractor in a separate command window.
protractor conf.js
(In my case conf.js was the config file )
I faced a similar issue to the one #David Remie faced with the Selenium Docker grid/standalone. With minimal RAM/CPU, the tests would start before the webdriver was up. A less resource consuming approach is to wait a few seconds before testing (run 'sleep 5' or something like that).
Increasing RAM was sometimes enough as a workaround for the issue, but the real problem was that the Selenium CMD (/opt/bin/entry_point.sh, starts a supervisor that runs the webdriver) from the image based on https://hub.docker.com/r/selenium/node-base/dockerfile was taking time to start the Selenium webdriver.
webdriver-manager start ----- didn't help, But below one helped
webdriver-manager start --standalone
