   public static void main(String[] args) 

   {



   }

}

我正在 eclipse 中工作，正在制作一个 selenium webdriver，我需要能够使用命令行参数，在其中为其提供应用程序名称和环境名称(均为枚举)，然后它运行测试。我知道我需要在 eclipse 参数框中放一些东西运行|运行配置|争论但我不确定是什么。任何帮助，将不胜感激。

尝试:

public static void main(String[] args) {
    try {
        App argArg = App.valueOf(args[0]);
        ENV argENV = ENV.valueOf(args[1]);
    } catch(IllegalArgumentException e) {
        printHelp();
        System.exit(1);
    }
    ...
}

在 printHelp() 中，您可以列出所有可能的值:

StringBuffer appParamHelp = new StringBuffer("Possible 'App' values are:");
for(App possibleAppVal : App.values) {
    appParamHelp.append(" ");
    appParamHelp.append(possibleAppVal.name());
}
