Question

帮助 - 我是Selenium Webdriver的新手。我已经在VS 2015上安装了selenium weddriver。

当我尝试并运行时

IWebDriver driver = new FirefoxDriver();

我总是得到一个

system.collections.generic.KeyNotFoundException“在字典中找不到密钥”。

我知道我需要一个webdriver.json文件，这是我的：

{
    "capabilities":
    [
        {
        "browserName": "firefox",
        "version": "48.0.2",
        "platform": "WINDOWS",
        "maxInstances": 1
         },
        {
        "browserName": "internet explorer",
        "version": "11",
        "platform": "WINDOWS",
        "maxInstances": 1
        }
    ],
    "configuration":
    {
    "nodeTimeout":120,
    "port":5555,
    "hubPort":4444,
    "hubHost":"localhost",
    "nodePolling":2000,
    "registerCycle":10000,
    "register":true,
    "cleanUpCycle":2000,
    "timeout":30000,
    "maxSession":1,
    }
}

我有两个主要问题： 1）我不知道缺少哪个密钥 2）我试图在没有运气的情况下搜索这个json文件的文档和示例。

我的Selenium安装，参考和使用声明似乎都符合安装说明。

Selenium“new firefoxdriver（）”抛出KeyNotFoundException
