我对硒很陌生。我试图编写一个脚本来打开一个应用程序，输入用户名和密码并登录。我尝试在firefox中使用selenium进行同样的操作。起作用了。但是，当我使用selenium和TestNG(JAVA)进行同样的操作时，我会得到以下错误：

    org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of element located by By.xpath: /html/body/form[1]/div[2]/table[2]/tbody/tr[4]/td/button (tried for 10 second(s) with 500 MILLISECONDS interval)

我页面的HTML片段是：

                            <table>
                                <tr>
                                    <td>User Id: </td>
                                    <td><input type="text" name="USER" id="USER" onfocus="this.style.border='2px solid #3BB9FF';" onblur="this.style.border='2px solid #737373'" /></td>
                                </tr>
                                <tr>
                                    <td>Password: </td>
                                    <td><input type="password" name="PASSWORD" id="PASSWORD" onfocus="this.style.border='2px solid #3BB9FF';" onblur="this.style.border='2px solid #737373'" /></td>
                                </tr>
                                <tr>
                                    <td><input type="hidden" name="TARGET" id="TARGET" value="/epsweb/view/private/search/search.jsf" /></td>
                                </tr>
                                <tr>
                                    <td><button name="Logon" type="submit" onfocus="this.style.border='2px solid #3BB9FF';" onblur="this.style.border='2px solid #737373'">Logon</button></td>
                                </tr>
                            </table>

我的TESTNG java代码：

public void userLogin(){
        driver.get(baseURL + "login url");
        //driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        //driver.findElement(By.id("USER")).sendKeys("aaa");
        waitVar.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"USER\"]"))).sendKeys("aaa");
       waitVar.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id=\"PASSWORD\"]"))).sendKeys("123");;
    //  driver.findElement(By.name("USER")).sendKeys("aaa");
    //  driver.findElement(By.name("PASSWORD")).sendKeys("@123");
        waitVar.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("/html/body/form[1]/div[2]/table[2]/tbody/tr[4]/td/button"))).click();
        String strPageTitle = driver.getTitle();

    }

我试过使用多种组合，但现在起作用了。我甚至尝试从firefox复制代码并将其转换为java。XPATH正在从firebug中获取信息。

注意:表单元素在10秒前就可以看到。

更新:我尝试使用以下代码

 WebElement myelement=driver.findElement(By.id("USER"));
String tag=myelement.getTagName();
        System.out.println("====================="+tag);// ===============input
        myelement.sendKeys("aaaa");

系统线正在打印。但是，当我使用sendKeys()方法时，它会抛出异常。
