How to use @FindBy annotation in Selenium WebDriver

Question

I want to know what wrong with my code, because when I try to test my code, I didn´t get anything.

public class SeleniumTest {

private WebDriver driver;
private String nome;
private String idade;

@FindBy(id = "j_idt5:nome")
private WebElement inputNome;

@FindBy(id = "j_idt5:idade")
private WebElement inputIdade;

@BeforeClass
public void criarDriver() throws InterruptedException {

    driver = new FirefoxDriver();
    driver.get("http://localhost:8080/SeleniumWeb/index.xhtml");
    PageFactory.initElements(driver, this);

}

@Test(priority = 0)
public void digitarTexto() {

    inputNome.sendKeys("Diego");
    inputIdade.sendKeys("29");

}

@Test(priority = 1)
public void verificaPreenchimento() {

    nome = inputNome.getAttribute("value");
    assertTrue(nome.length() > 0);

    idade = inputIdade.getAttribute("value");
    assertTrue(idade.length() > 0);
}

@AfterClass
public void fecharDriver() {

    driver.close();

}

}

I´m using Selenium WebDriver and TestNG, and I tried to test some entries in JSF page.

There's a difinition for @BeforeClass :

@BeforeClass
Run before all the tests in a class

And @FindBy is "executed" each time that you'll call the class.

Actually your @FindBy is called before the @BeforeClass so it won't work.

What i can suggest to you is to keep the @FindBy but let's start to use the PageObject pattern.

You keep your test's page and you create another class for your objects like :

public class PageObject{
  @FindBy(id = "j_idt5:nome")
  private WebElement inputNome;

  @FindBy(id = "j_idt5:idade")
  private WebElement inputIdade;

  // getters
  public WebElement getInputNome(){
    return inputNome;
  }

  public WebElement getInputIdade(){
    return inputIdade;
  }

  // add some tools for your objects like wait etc
} 

Your SeleniumTest'll looks like that :

@Page
PageObject testpage;

@Test(priority = 0)
public void digitarTexto() {

  WebElement inputNome = testpage.getInputNome();
  WebElement inputIdade = testpage.getInputIdade();

  inputNome.sendKeys("Diego");
  inputIdade.sendKeys("29");
}
// etc

If you're going to use this tell me what's up.
