java - 使用 IEDriverServer 3.9.0.0 运行 selenium 时无法启动 IE 11

Question

当我运行 selenium 测试时，启动 IE 11 时遇到问题。这是我用来设置浏览器的代码

 if (browser.equalsIgnoreCase("ie")) {
        System.setProperty("webdriver.ie.driver",  "IEDriverServer.exe");
        driver = new InternetExplorerDriver();
    } else {
        throw new Exception("Browser is not correct");
    }
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    driver.get("https://www.google.com/");
    Dimension dimension = new Dimension(800,600);
    driver.manage().window().setSize(dimension);
}

我尝试了基于此线程的其他解决方案，但仍然没有运气。 Stack Link 。我可以使用任何解决方案吗？

环境:
Selenium 版本:3.12.0
IEDriverServer版本:3.9.0.0
IE版本:11.0.65

控制台输出:

 Started InternetExplorerDriver server (64-bit)
 3.9.0.0
 Listening on port 10696
 Only local connections are allowed

Answer 1

此错误消息...

org.openqa.selenium.WebDriverException: java.net.SocketException: Connection reset

...暗示 IEDriverServer 无法启动/生成新的 WebBrowsing session ，即 InternetExplorer 浏览器 session 。

您的主要问题是您使用的二进制文件版本之间不兼容，如下所示:

• 您的 Selenium 客户端 版本是 2018-05-08T14:04:26.12Z 的 3.12.0，比旧版本快一年了。
• 您的 InternetExplorerDriver 版本 3.9.0.0。

因此，Selenium Client v3.12.0 和 InternetExplorerDriver v3.9.0.0 之间存在明显的不匹配。根据最佳实践，Selenium Client 和 InternetExplorerDriver 同步发布，您必须使用同一主要版本中的两个二进制文件强>.

<小时/>

此外，InternetExplorerDriver 服务器 v3.9.0.0 存在一个已知问题，如下引用文献所示:

• Can't launch Selenium IE Driver after upgrading to version 3.9
• Selenium Java Client (v3.9.1) with IEDriverServer v3.9.0.0 (64-bit) crashes with org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:28286

此问题已通过以下提交得到解决:

• Properly initializing JSON values in IE driver

解决方案

• 将 IEDriverServer 升级到当前 IEDriverServer v3.12.0级别。
• 通过IDE清理您的项目工作区，并仅使用所需的依赖项重建项目。
• 使用CCleaner工具可以清除执行测试套件之前和之后的所有操作系统杂务。
• 重新启动系统。
• 执行您的@Test。
• 始终在 tearDown(){} 方法中调用 driver.quit() 来关闭和销毁 WebDriver 和 Web Client 优雅地实例化。
