Set Chrome's language using Selenium ChromeDriver

Question

I download ChromeDriver and by defaults the browser language is in English, I need to change it to Spanish, and I have been unable.

public WebDriver getDriver(String locale){   
    System.setProperty("webdriver.chrome.driver", "driver/chromedriver.exe");
    return new ChromeDriver();
}

public void initializeSelenium() throws Exception{
    driver = getDriver("en-us")
}

Answer 1

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
}
