用于 GMail 登录的 Java 中的 Selenium webdriver 脚本

Question

我已经编写了此代码来登录 GMail，但它不起作用。

它继续直到电子邮件 id 才显示以下错误：

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate element: {"method":"id","selector":"Passwd"}

有没有可能解决这个问题？

Answer 1

您应该使用显式等待。 看看这里的文档。

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(
           ExpectedConditions.visibilityOfElementLocated(By.id("Passwd")));
driver.findElement(By.id("Passwd")).sendKeys("xyz");
