You should replace WebDriver wb = new FirefoxDriver();with driver = new FirefoxDriver();in your @BeforeAnnotation.

您应该在注释中替换WebDriver wb = new FirefoxDriver();为。driver = new FirefoxDriver();@Before

As you are accessing driverobject with null or you can make wbreference variable as global variable.

当您driver使用 null访问对象时，或者您可以将wb引用变量设为全局变量。

This is simple if you only use Selenium WebDriver, and forget the usage of Selenium-RC. I'd go like this.

如果您只使用 Selenium WebDriver 而忘记使用 Selenium-RC，这很简单。我会这样。

WebDriver driver = new FirefoxDriver();
WebElement email = driver.findElement(By.id("email"));
email.sendKeys("[email protected]");

The reason for NullPointerExceptionhowever is that your variable driverhas never been started, you start FirefoxDriverin a variable wbthas is never being used.

NullPointerException然而，原因是您的变量driver从未启动过，您从FirefoxDriver一个wb从未使用过的变量开始。

Try this :

尝试这个 ：

    driver.findElement(By.id("email")).clear(); 
driver.findElement(By.id("email")).sendKeys("[email protected]");

Another way to solve this using xpath

使用 xpath 解决此问题的另一种方法

WebDriver driver =  new FirefoxDriver();
driver.get("https://www.facebook.com/");
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
driver.findElement(By.xpath(//*[@id='email'])).sendKeys("[email protected]");

Hope that will help. :)

希望这会有所帮助。:)

You can use JavaScript as well, in case the textfield is dithered.

您也可以使用 JavaScript，以防文本字段抖动。

WebDriver driver=new FirefoxDriver();
driver.get("http://localhost/login.do");
driver.manage().window().maximize();
RemoteWebDriver r=(RemoteWebDriver) driver;
String s1="document.getElementById('username').value='admin'";
r.executeScript(s1);
