How to change chrome browser language in selenium

Question

I want to automate localization functions of a web application. According to my application when the browser language changes, application language should change automatically according to the browser language. How to do that?

Answer 1

Set the language code in chrome options before launching the the driver as shown below.

System.setProperty("webdriver.chrome.driver","<PATH>/chromedriver.exe");
ChromeOptions chromeoptions = new ChromeOptions();
// for japanese language
chromeoptions.addArguments("–lang= ja");
ChromeDriver driver = new ChromeDriver(chromeoptions);
driver.get("https://www.google.com");
