Nightwatch - Use chromedriver - selenium-chromedriver

Question

So i saw a similar question on stack here but it did not have an accepted answer nor did it provide me with the information i needed..
I am trying to use 'chromedriver' because 'selenium-webdriver' requires a FF version <= 28.
What i've done so far.
nightwatch.js tests running fine in FF
downloaded chromedriver (npm install chromedriver -g) and also npm install chromedriver into my nightwatch project directory
went to nightwatch/bin/nightwatch.json and edited the following code
"selenium" : {
"start_process" : false,
"server_path" : "",
"log_path" : "",
"host" : "127.0.0.1",
"port" : 4444,
"cli_args" : {
"webdriver.chrome.driver" : "/usr/local/bin/chromedriver", <= added this - is this the binary?
"webdriver.ie.driver" : "",
"webdriver.firefox.profile" : ""
}},
also tried to update the settings for selenium to have a start_process=true and server_path
"selenium" : {
"start_process" : true,
"server_path" : "../selenium-server-standalone-2.39.0.jar",
"log_path" : "",
"host" : "127.0.0.1",
"port" : 4444,
"cli_args" : {
"webdriver.chrome.driver" : "/usr/local/bin/chromedriver",
"webdriver.ie.driver" : "",
"webdriver.firefox.profile" : ""
}
},
Not sure if im pointing to the proper chromedriver file/folder
also edited the test settings
"test_settings" : {
"default" : {
"launch_url" : "http://localhost",
"selenium_host" : "127.0.0.1",
"selenium_port" : 4444,
"silent" : true,
"disable_colors": false,
"screenshots" : {
"enabled" : false,
"path" : ""
},
"desiredCapabilities" : {
"browserName" : "chrome", <= changed this from ff to chrome
"javascriptEnabled" : true,
"acceptSslCerts" : true
}
},
If i go to run the test (without a -e <browser>) e.g. nightwatch -g <group>, it launches fine in FF and runs..
If i try to specify the chrome browser (-e chrome) nightwatch -g <group> -e chrome i get the following error
ERROR There was an error while starting the test runner:
Error: Invalid testing environment specified: chrome

at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
The questions i have are:
How do i point to the binary file (not sure which it is)
Are my settings in nightwatch.js correct? How is it running in FF if i changed the test_settings 'browserName = Chrome"?
Am i missing something here?
Thanks in advance

Answer 1

First you said
I am trying to use 'chromedriver' because 'selenium-webdriver'
requires a FF version <= 28.
Its because you are using selenium-server-standalone-2.39.0.jar (Old jar) Please download new one from here selenium-server-standalone-2.45.0.jar
Second Download chrome driver from here Chromedriver basis on your environment
Third update your nightwatch.json with below code
{
"src_folders": [
"tests"
],
"selenium": {
"start_process": false,
"server_path": "bin/selenium-server-standalone-2.45.0.jar",
"log_path": "",
"host": "127.0.0.1",
"port": 4444,
"cli_args": {
"webdriver.chrome.driver": "bin/chromedriver",
"webdriver.ie.driver": ""
}
},
"test_settings": {
"default": {
"launch_url": "http://127.0.0.1/",
"selenium_port": 4444,
"selenium_host": "localhost",
"silent": true,
"screenshots": {
"enabled": false,
"path": ""
},
"desiredCapabilities": {
"browserName": "firefox",
"javascriptEnabled": true,
"acceptSslCerts": true
}
},
"chrome": {
"desiredCapabilities": {
"browserName": "chrome",
"javascriptEnabled": true,
"acceptSslCerts": true
}
}
}
}
Fourth run your group with nightwatch -g -e chrome
Hope It will solve your problem.

Answer 2

Make sure to create a new nightwatch.json file in the root of your project.
The mistake i made was trying to use the nightwatch.json file that came with the package downlaoded from http://nightwatchjs.org/ that resided in nightwatch-0.6.11/bin/nightwatch.json

Answer 3

"selenium": {
"start_process":true,
"server_path": "bin/selenium.jar",
"log_path": "",
"host": "127.0.0.1",
"port": 4444,
"cli_args": {
"webdriver.chrome.driver": "",
"webdriver.ie.driver": ""
}
},
above code helps me to run selenium server by nightwatch
