Question

我的代码是

    public static void main(String[] args) {
    // declaration and instantiation of objects/variables
    WebDriver driver = new FirefoxDriver();
    driver.navigate().to("http://gmail.com");

    System.out.println(driver.getTitle());

    WebElement element = driver.findElement(By.xpath("//*[@id='Email']"));
    element.sendKeys("asangal90@gmail.com");

    element = driver.findElement(By.name("signIn"));
    element.click();

    element = driver.findElement(By.xpath("//*[@id='Passwd']"));
    element.sendKeys("123456");

    element = driver.findElement(By.name("signIn"));
    element.click();

        }

错误是：

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"xpath","selector":"//*[@id='Passwd']"}

目前，驱动程序不会等待DOM中存在的元素。定义隐式等待以告诉驱动程序在抛出异常之前等待一段时间

driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

这将告诉司机搜索最多5秒的元素。
