Question

我是selenium web驱动程序的新手，我正在编写脚本登录到下面的gmail是我创建的测试脚本。

公共类gmailEmail {

public void login() {
    ChromeDriver driver=new ChromeDriver();
    driver.get("https://www.gmail.com");
    driver.findElementById("Email").sendKeys("XXXXX@gmail.com");
    driver.findElementByName("signIn").click();
    driver.findElementById("Passwd").sendKeys("XXXX");
    //driver.findElementByXPath("//*[@id='Passwd']").sendKeys("XXXXX");
    driver.findElementByXPath("//*[@id='signIn']").click();     
}

当我运行此错误时，错误是在＆＃34; driver.findElementById（＆＃34; Passwd＆＃34;）＆＃34;正在显示以下错误消息

Exception in thread "main" org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"id","selector":"Passwd"}

如果我通过在＆＃34; driver.findElementById（＆＃34; Passwd＆＃34;）＆＃34;处插入断点来进行调试。然后整个脚本工作正常。

有人可以帮助我理解我在这里做错了吗？

Answer 1

该错误表明，当selenium执行输入密码的命令时，它无法识别该元素，该元素未在UI中加载或不可见。

您可能希望使用ImplicitWait或ExplicitWaits。你可以阅读它们here

您可以尝试ExplicitWait等待Passwd元素：

public void login() {
ChromeDriver driver=new ChromeDriver();
driver.get("https://www.gmail.com");
driver.findElementById("Email").sendKeys("XXXXX@gmail.com");
driver.findElementByName("signIn").click();
WebDriverWait wait = new WebDriverWait(driver, 30); 
wait.until(ExpectedConditions.presenceOfElementLocated(By.id("Passwd")).sendKeys(""What ever");
    driver.findElementByXPath("//*[@id='signIn']").click();     
}

Answer 2

尝试使用以下代码：

/Root/{Name}/{Name}

添加Chrome驱动程序功能

Answer 3

尝试一次。

WebDriver driver = new ChromeDriver();
driver.get("https://www.gmail.com");
driver.manage().timeouts().impliciltyWait(30,TimeUnit.SECONDS);
driver.findElement(By.id("email-display").sendKeys("XXXXX@gmail.com");
driver.findElement(By.id("next"").click();
driver.findElement(By.id("Passwd")).sendKeys("xxxxxx");
    driver.findElementByXPath("//*[@id='signIn']").click();

为什么我无法在新的Gmail登录页面中使用selenium web驱动程序处理密码字段？
