Question

我希望用WebDriver在selenium PageFactory中编写测试，但如果我在课程中以PageFactory形式添加注释

@FindBy(id="email")
public WebElement mailLink;

和用法：

mailLink.sendKeys("mail@mail.com");

我每次都得NullPointerException。另一种方式：

driver.findElement(By.id("email")).sendKeys("mail@mail.com");

返回正确的值。第一种方法的问题在哪里？

我的代码：

我在FaceClass中进行了驱动程序初始化：

public class FaceClass {

protected WebDriver driver;

public FaceClass(WebDriver driver){
    this.driver = driver;
}

public HomePage navigateToApp(){
    driver.navigate().to("https://facebook.pl");

    return PageFactory.initElements(driver, HomePage.class);
}

}

和具有业务逻辑的类：

public class HomePage extends FaceClass{

public HomePage(WebDriver driver) {
    super(driver);
    // TODO Auto-generated constructor stub
}


@FindBy(id="email")
public WebElement mailLink;

@FindBy(id="pass")
public WebElement passLink;

@FindBy(how = How.ID, using="u_0_n")
public WebElement loginButton;


public ProfilePage navigateToProfile(){

    try{

        if(driver.findElement(By.id("pass")).isEnabled() || driver.findElement(By.id("pass")).isDisplayed()){
            System.out.println("ok!");
        }



    //driver.findElement(By.id("pass")).sendKeys("pass_to_account");
    //driver.findElement(By.id("email")).sendKeys("mail@mail.com");
    //driver.findElement(By.id("u_0_n")).click();
    mailLink.sendKeys("mail@mail.com");
    passLink.sendKeys("pass_to_account");
    loginButton.click();

    } catch (Exception e) {
        e.printStackTrace();
        }

    return PageFactory.initElements(driver, ProfilePage.class);
}

}

并测试：

    public class ExampleTest {

WebDriver driver;

@Before
public void setUp() throws Exception {

    System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe");
    DesiredCapabilities capabilities=DesiredCapabilities.chrome();
    capabilities.setCapability("marionette", true);
    driver = new ChromeDriver();
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    driver.navigate().to("https://facebook.pl");
}

@After
public void tearDown() throws Exception {

    driver.quit();
}

@Test
public void test() {
    //fail("Not yet implemented");
    HomePage homepage = new HomePage(driver);
    homepage.navigateToProfile();

}

}

所有元素均已启用且可见

Answer 1

在使用之前，您没有初始化元素。初始化页面元素PageFactory方法initElements。如果你在你的构造函数中调用它会更好：

public HomePage(WebDriver driver) {
    super(driver);
    PageFactory.initElements(driver, this);
}

希望它有效。

pageFactory（webdriver）中的FindBy无法正常工作
