java - UnreachableBrowserException 尝试使用 IEDriver 在 Selenium Webdriver 中启动

Question

我有一套在 Firefox 和 Chrome 中运行良好的自动化功能，并且我还想启动 IEDriver 的实例。

我已按照 Selenium's Google Code wiki 设置 IEDriver ，具有正确的路径(如果我更改路径，我会得到不同的异常，所以它绝对是正确的)。但由于某种原因它仍然无法启动，并且只是超时。

启动它的代码(最后一行抛出异常):

        File ieDriver = new File("C:/Users/whatever/path/IEDriverServer.exe");
        System.setProperty("webdriver.ie.driver", ieDriver.getAbsolutePath());
        WebDriver ie = new InternetExplorerDriver();

异常(exception)是:

Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

Answer 1

我遇到了同样的错误，然后发现了这个问题。就我而言，事实证明我的系统上有 64 位版本的 IEDriver.exe，但我使用的是 32 位 Windows 平台。所以这个错误表明操作系统未能执行驱动程序。我尝试直接在命令提示符下运行驱动程序，结果发现 32 位操作系统并未将 64 位驱动程序 exe 识别为可执行程序。

获取正确的 32 位 IEDriver.exe 解决了我的问题。
