selenium测试问题

[dai_zi]

在学习selenium1案例时 OPen本址文件时报异常，查询在网上一直没找到原因：
java代码
DefaultSelenium selenium=new DefaultSelenium("localhost", 4444, "*firefox C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe", "https://www.baidu.com/index.php?tn=monline_3_dg");
selenium.start();
selenium.open("C:\\Users\\daixiaofei\\Desktop\\test.html");

报出来的异常：
Exception in thread "main" com.thoughtworks.selenium.SeleniumException: ERROR: Command execution failure. Please search the user group at
https://groups.google.com/forum/#!forum/selenium-users for error details from the log window. The error message is: Component returned failure
