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 } 

Answer 2

For me, --lang didn't work. It seems to set the language of the first opened tab, all others chrome processes are started with --lang=en-US.

What did work is the following:

DesiredCapabilities jsCapabilities = DesiredCapabilities.chrome(); ChromeOptions options = new ChromeOptions(); Map<String, Object> prefs = new HashMap<>(); prefs.put("intl.accept_languages", language); options.setExperimentalOption("prefs", prefs); jsCapabilities.setCapability(ChromeOptions.CAPABILITY, options);
