java - 通过 Java 和 Selenium 启动 Internet Explorer 时出现 "OsProcess checkForError : CreateProcess error=193, %1 is not a valid Win32 application"

Question

我正在 Eclipse (Java) 中使用 Selenium 驱动程序，我想创建一个驱动程序来测试 Internet Explorer 页面，但我不断收到此错误消息，我的驱动程序在 firefox 和 chrome 上运行良好，但在资源管理器中我无法测试任何内容

System.setProperty("webdriver.ie.driver", "C:\\Users\\emorales\\Documents\\MicrosoftWebDriver.exe");
//set webdriver to explorer  test
WebDriver driver = new InternetExplorerDriver();

//metodo para obtener url
driver.get("http://google.com");

System.out.println(driver.getTitle());

这是我的错误堆栈跟踪:

Answer 1

此错误消息...

org.openqa.selenium.os.OsProcess checkForError
SEVERE: org.apache.commons.exec.ExecuteException: Execution failed (Exit value: -559038737. Caused by java.io.IOException: Cannot run program "C:\Users\emorales\Documents\MicrosoftWebDriver.exe" (in directory "."): CreateProcess error=193, %1 is not a valid Win32 application)

...意味着底层操作系统无法启动/生成新的WebBrowsering session ，即Internet Explorer浏览器 session 。

根据您的代码试验，您尝试将 WebDriver 实例(即驱动程序)转换为 InternetExplorerDriver() ，所以在 System.setProperty() 行内您需要提供相应 IEDriverServer 二进制文件的绝对路径(但不是MicrosoftWebDriver.exe)。

您可以从Index Page下载相关的IEDriverServer二进制版本并在您的代码中提及:

System.setProperty("webdriver.ie.driver", "C:\\path\\to\\IEDriverServer.exe");
//set webdriver to explorer  test
WebDriver driver = new InternetExplorerDriver();

//metodo para obtener url
driver.get("http://google.com");

System.out.println(driver.getTitle());
