ChromeOptions causes reference error using Seleniu

Question

I am trying to use the ChromeDriver driver for Selenium to run some tests using Chrome, but I'm getting a reference error when I use ChromeOptions.

My Code

I want to force the use of certain options, such as testing it against a particular user profile. Based on the Selenium and ChromeDriver documentation, this is my file test.js:

opt = new chromeOptions(); // ERROR OCCURS HERE!
opt.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
opt.addArguments("--user-data-dir=C:\\Users\\MyUserAccount\\AppData\\Local\\Google\\Chrome\\User Data");
driver = new ChromeDriver(opt);

// rest of my script goes here

The error

I am executing this using the command node test.js. This throws the following error on the first line:

\path\to\test.js:1

ction (exports, require, module, __filename, __dirname) { opt = new chromeOpti
                                                                    ^
ReferenceError: chromeOptions is not defined
    at Object.<anonymous> (\path\to\test.js:1:73)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:902:3

For what it's worth, if I skip setting options and replace the first four lines of the script with this, it works, but I can't set the options I need to set:

var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder().
    withCapabilities(webdriver.Capabilities.chrome()).
    build();

I'm sure that I'm missing something really basic, but I can't figure this one out. How can I set options for Chrome using Selenium and node.js?

Edited to remove some obviously invalid syntax from the samples in some of the documentation I found.

Answer 1

could you please just try below solution

var webdriver = require("selenium-webdriver");
var chrome = require("selenium-webdriver/chrome");

/** 
 * Set chrome command line options/switches
*/      
var chromeOptions = new chrome.Options();
chromeOptions.addArguments("test-type");
chromeOptions.addArguments("start-maximized");
chromeOptions.addArguments("--js-flags=--expose-gc");
chromeOptions.addArguments("--enable-precise-memory-info");
chromeOptions.addArguments("--disable-popup-blocking");
chromeOptions.addArguments("--disable-default-apps");
chromeOptions.addArguments("--disable-infobars");

driver = new webdriver.Builder()
             .forBrowser("chrome")
             .setChromeOptions(chromeOptions)
             .build();

driver.get("http://www.google.com")

Answer 2

This works for me (from this gist)

//import the selenium web driver
var webdriver = require('selenium-webdriver');

var chromeCapabilities = webdriver.Capabilities.chrome();
//setting chrome options to start the browser fully maximized
var chromeOptions = {
    'args': ['--test-type', '--start-maximized']
};
chromeCapabilities.set('chromeOptions', chromeOptions);
var driver = new webdriver.Builder().withCapabilities(chromeCapabilities).build();

Answer 3

This seems to be a fundamental OOP JavaScript misunderstanding!

Your problem is:

ChromeOptions opts = new chromeOptions();

You don't instantiate objects this way. Try:

var opt = new ChromeOptions();

Here's proof: http://jsfiddle.net/q5Etk/

If you run that, we get "Unexpected Identifier". Uncomment the var bit and comment the Cat cat bit and see it work.

EDIT After your edit:

You are specifying chromeOptions(). It's ChromeOptions() capped C

Answer 4

The following works for me:

var webdriver = require("selenium-webdriver");
var chrome = require("selenium-webdriver/chrome");

// Make sure the PATH is set to find ChromeDriver. I'm on a Unix
// system. You'll need to adapt to whatever is needed for
// Windows. Actually, since you say that you can get a browser to show
// up if you don't try to specify options, your ChromeDriver is
// probably already on your PATH, so you can probably skip this.
process.env["PATH"] += ":/home/user/src/selenium/";

var options = new chrome.Options();

// Commented out because they are obviously not what you want.
// Uncomment and adapt as needed:
//
// options.setChromeBinaryPath("/tmp/foo");
// options.addArguments(["--blah"]);

var driver = new webdriver.Builder().
   withCapabilities(options.toCapabilities()).build();

driver.get("http://www.google.com")

I've tested the code above with various values and found that it works.

If you want to see what else you can do with the Options object, you can open node_modules/selenium_webdriver/chrome.js and read the source. This is how I figured out the above method.
