我有一段代码直到今天都运行得很好。
public class TestSelenium {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver","chromedriver\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("https://google.com");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.findElement(By.name("q")).sendKeys("hello world");
}
}
上面的简单代码会引发以下错误:

我很困惑......Fluent wait有什么问题？ Selenium 是否有任何更改，或者这种错误是否可能是由于自动 Java 升级造成的？
(PS:我没有手动升级Java和Selenium)我需要升级ChromeDriver吗？我尝试搜索最新版本，但找不到比我使用的版本更新的版本
我还尝试了以下方法:
public class TestSelenium {
public static void main(String[] args) {
WebDriver driver = new HtmlUnitDriver();
driver.get("https://google.com");
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.findElement(By.name("q")).sendKeys("hello world");
System.out.println("hi");
}
}
上面的代码工作正常...那么这是否意味着问题出在 chrome 驱动程序上？？？
最佳答案
我们的回归系统也产生了这个错误。升级到最新的 ChromeDriver，一切就搞定了。
所有在后台运行 GoogleUpdate 的 Selenium 2 用户都会遇到这种情况。 chrome v29一出来，似乎就与旧的chromedriver脱节了。更新到最新的 chromedriver，似乎可以解决该问题。
您可以找到二进制文件 here
关于java - ChromeDriver 功能是否已被弃用？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18436156/
