硒/火狐不工作

Question

我正在尝试使用 Java 代码通过 selenium webdriver 调用 Firefox，Firefox 浏览器打开，但是，它没有运行任何测试，并且在一段时间后终止并出现以下错误消息。请帮忙。

Answer 1

这是因为最新的 Firefox 浏览器出现了新问题。

更新您的硒罐。新版本的firefox（或其他浏览器）不支持selenium的旧jar。

同时下载 Selenium Server（以前的 Selenium RC Server）Selenium Client 和 WebDriver 语言绑定

用您正在使用的旧罐子替换它们。也更新您的 Mozilla，以便您获得更新的结果

为了解决这个问题，您还需要将 Preference 设置为 xpinstall.signatures.required", false 到 firefox 配置文件，然后将其传递给驱动程序对象

firefoxProfile.setPreference("xpinstall.signatures.required", false);

下面的代码对我来说很好。

static WebDriver driver=null;
public static void main(String[] args) {
final FirefoxProfile firefoxProfile = new FirefoxProfile();
firefoxProfile.setPreference("xpinstall.signatures.required", false);
driver = new FirefoxDriver(firefoxProfile);
driver.get("https://www.google.de/");

希望对你有帮助:)
