通过Java和Selenium启动Internet Explorer时，“OsProcess checkForError：CreateProcess error = 193，％1不是有效的Win32应用程序”

Question

我正在使用Eclipse（Java）中的Selenium Driver，我想创建一个驱动程序来测试Internet Explorer页面并且我不断收到此错误消息，我的驱动程序与firefox和chrome一起工作正常但是使用explorer我无法测试任何东西

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)

...暗示底层操作系统无法启动/生成新的WebBrowsering会话，即Internet Explorer浏览器会话。

根据您的代码试验，您正在尝试将WebDriver实例（即驱动程序）转换为InternetExplorerDriver()，因此在System.setProperty()行中，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());
