P.O.M Cont-d
public class LoginPage
{
//Locators assigned to variables
@FindBy(how = How.ID, using = “password")
private static WebElement passwordTextField = null;
@FindBy(how = How.NAME, using = “username")
private static WebElement userNameTextField = null;
@FindBy(how = How.XPATH, using = "//input[@name=‘loginButton’]")
private static WebElement loginButton = null;
//Expose methods
public HomePage login(String userName, String password )
{
userNameTextField.sendKeys(userName);
passwordTextField.sendKeys(password);
loginButton.click();
return new HomePage();
}
}
Then in any test class we can call above function like :
LoginPage loginPage=new LoginPage();
HomePage homePage=loginPage.login(“singmaz”,”pass123#”);
