DesiredCapabilities capabilities = DesiredCapabilities.firefox();

capabilities.setCapability("marionette", true);

driver=new FirefoxDriver();

driver.get("https://gmail.com");

WebElement username = driver.findElement(By.id("Email"));

username.sendKeys("shruti.shrivastava.in");

driver.findElement(By.id("next")).click();

driver.findElement(By.id("signIn")).click();

 

I am getting the folowing erro message -:

Answer 1

You will have to use WebDriverWait. As, when you press the "Next" button, Password field is loaded using Javascript. So, you should use WebDriverWait to wait for an element to be loaded.

 

driver.findElement(By.id("next")).click();

WebDriverWait wait = new WebDriverWait(driver,10);

wait.until(ExpectedConditions.elementIsVisible(By.id("Passwd")));

driver.findElement(By.id("Passwd")).sendKeys("password");

 

Hope tha thelps!
