Chromedriver: How to translate a page using selenium? - selenium

Question

I need to translate a page from Japanese to English, using selenium in chrome browser. I tried different ways one of sample code snippet is as following
import java.util.concurrent.TimeUnit;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.DesiredCapabilities;
public class Main {
private WebDriver driver=null;
WebDriverLoad a;
#Test
public void successfulDesignerLogin() throws Exception{
// final DesiredCapabilities capabilities = DesiredCapabilities.chrome();
// capabilities.setJavascriptEnabled(true);
String chromedriver = "/dev/Saved/chromedriver";
System.setProperty("webdriver.chrome.driver",chromedriver);
ChromeOptions options = new ChromeOptions();
options.addArguments("--lang=en-ca");
//Map<String, Object> prefs = new HashMap<String, Object>();
//prefs.put("intl.accept_languages", "en,en_US");
//options.setExperimentalOption("prefs", prefs);
ChromeDriver driver = new ChromeDriver(options);
driver.manage().timeouts().implicitlyWait(4, TimeUnit.SECONDS);
driver.get("https://www.bbc.com/japanese");
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
driver.close();
}
}
I tried a couple of solution options.addArguments options.setExperimentalOption but nothing works can any one suggests me what can be the solution

Answer 1

You need to enable translate and add target language ID to the whitelist {"from" : "to"}.
"translate":{"enabled":"true"}
"translate_whitelists": {"ja":"en"}
in java:
Map<String, Object> prefs = new HashMap<String, Object>();
Map<String, Object> langs = new HashMap<String, Object>();
langs.put("ja", "en");
prefs.put("translate", "{'enabled' : true}");
prefs.put("translate_whitelists", langs);
options.setExperimentalOption("prefs", prefs);

Here is a C# version, directly add "translate" and "translate_whitelists" in "AddUserProfilePreference"
ChromeOptions options = new ChromeOptions();
Dictionary<string, object> LanguageList = new Dictionary<string, object>();
LanguageList.Add("fr", "en");
Dictionary<string, bool> enableObject = new Dictionary<string, bool>();
enableObj.Add("enabled", true);
options.AddUserProfilePreference("translate", enableObject);
options.AddUserProfilePreference("translate_whitelists", LanguageList);
