Unable to open Chrome WebDriver in another language

Question

I'd really like to write a Selenium WebDriver test that verifies text is localized. The localization code bases the strings it displays on navigator.language (or navigator.userLanguage for IE). I cannot figure out, however, how to launch a Chromium window for a different language.

I see this bug which sort of explains the problem (closed as not a bug): https://code.google.com/p/chromium/issues/detail?id=114606

Here's how I create the browser instance:

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

var options = new chrome.Options();
options.addArguments('--lang=es');
var caps = options.toCapabilities();
var driver = webdriver.Builder().withCapabilities(caps).build();

I installed the Spanish language, but whereas navigator.languages includes es in its list, but even if I move it to the top of the preferences, en-US is still what navigator.language is set to.

Have any of you found a way to successfully write multi-language tests with Selenium WebDriver?

Answer 1

This code is working fine for me :

 System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");
     ChromeOptions options = new ChromeOptions();
     options.addArguments("--test-type");
     options.addArguments("--lang=hi");
     ChromeDriver wd;
     wd = new ChromeDriver(options);
     wd.manage().window().maximize();
     wd.get("http://google.com");

Its changing the language, showing up as first preferred language.

Answer 2

I resolved the error using this SO post.

The accepted answer from the question:

You can do it by adding Chrome's command line switches "--lang".

Basically, all you need is starting ChromeDriver with an ChromeOption argument --lang=es, see API for details.

The following is a working example of C# code for how to start Chrome in Spanish using Selenium.

ChromeOptions options = new ChromeOptions();
options.AddArguments("--lang=es");
ChromeDriver driver = new ChromeDriver(options);

Java code should be pretty much the same (untested). Remember, locale here is in the form language[-country] where language is the 2 letter code from ISO-639.

public WebDriver getDriver(String locale){   
    System.setProperty("webdriver.chrome.driver", "driver/chromedriver.exe");
    ChromeOptions options = new ChromeOptions();
    options.addArguments("--lang=" + locale);
    return new ChromeDriver(options);
}

public void initializeSelenium() throws Exception{
    driver = getDriver("es"); // two letters to represent the locale, or two letters + country
}

This works for me in JavaScript:

import { Builder, By, Key, until } from "selenium-webdriver";
import chrome from "selenium-webdriver/chrome";

const example = async () => {
      const options = await new chrome.Options();
      options.addArguments("--lang=es");
const driver = await new Builder().forBrowser("chrome").setChromeOptions(options).build();

      try {
        await driver.get("https://www.google.co.il");
      } finally {
        await driver.quit();
      }
    };
await example();
