I am working in Selenium. And I have got an error unable to locate element username. I'm using Java language. I am following page object design pattern.

Here is my code..


    WebElement username;
public void setUername(String usernam){
       WebDriverWait wait = new WebDriverWait(driver, 60);


AppointmentPage appointmentPageobj= PageFactory.initElements(DriverManager.driver,AppointmentPage.class);



AppointmentPage ex=log.Valid("9845612345","naveen","[email protected]","Demo","2017-03-04","Dr.biju");

Inspect locator:

<input type="text" id="user_name" value="" name="user_name" class="form-control">


org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"name","selector":"username"}

  • I believe you should use this @FindBy(how=How.XPATH,using=".//*[@id='user_name']")

  • Are you waiting for the element to be present in the DOM before performing any action on it. wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("xpath_details"))

1 Answer 1


Your element is wrong by standard ways. Change as per below :


In your code, change lines as per under :

  1. @FindBy(how=How.XPATH,using="//*[@id='user_name']")

  2. wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='user_name']")));

Xpath can not get element attribute with double quote (") symbol. Use single quote (').

Let come to Null Pointer exception

It might come for below scenario :

driver is not initialize properly. So try to change below line with existing :

WebDriverWait wait = new WebDriverWait(DriverManager.driver, 60);

Use DriverManager.driver when you need driver.
