OpenQA.Selenium.WebDriverException：'意外的服务器错误。'使用EdgeOptions

Question

我正在尝试使用C＃的Selenium WebDriver的W3C规范进行测试。根据阅读W3C文档here，这是我认为正确的代码。

    [Test]
    public void SimpleSelenium4Example()
    {

        //TODO please supply your Sauce Labs user name in an environment variable
        var sauceUserName = Environment.GetEnvironmentVariable("SAUCE_USERNAME", EnvironmentVariableTarget.User);
        //TODO please supply your own Sauce Labs access Key in an environment variable
        var sauceAccessKey = Environment.GetEnvironmentVariable("SAUCE_ACCESS_KEY", EnvironmentVariableTarget.User);

        var options = new EdgeOptions()
        {
            BrowserVersion = "latest",
            PlatformName = "Windows 10"
        };

        var sauceOptions = new JObject
        {
            ["username"] = sauceUserName,
            ["accessKey"] = sauceAccessKey,
            ["name"] = TestContext.CurrentContext.Test.Name
        };
        options.AddAdditionalCapability("sauce:options", sauceOptions.ToString());

        Driver = new RemoteWebDriver(new Uri("http://ondemand.saucelabs.com:80/wd/hub"), options.ToCapabilities(),
            TimeSpan.FromSeconds(600));
        Driver.Navigate().GoToUrl("https://www.google.com");
        Assert.Pass();
    }

我收到此错误OpenQA.Selenium.WebDriverException：'意外的服务器错误。'实例化RemoteWebDriver时。

不确定是什么问题。任何帮助表示赞赏。

.NET绑定适当地序列化对象;根本没有必要尝试使用Json.NET API（因为你使用JObject暗示你是这样），并且在通过线路传输之前序列化JSON对象（使用ToString()）可能是不成功的。

[Test]
public void SimpleSelenium4Example()
{
    //TODO please supply your Sauce Labs user name in an environment variable
    var sauceUserName = Environment.GetEnvironmentVariable("SAUCE_USERNAME", EnvironmentVariableTarget.User);
    //TODO please supply your own Sauce Labs access Key in an environment variable
    var sauceAccessKey = Environment.GetEnvironmentVariable("SAUCE_ACCESS_KEY", EnvironmentVariableTarget.User);

    var options = new EdgeOptions()
    {
        BrowserVersion = "latest",
        PlatformName = "Windows 10"
    };

    var sauceOptions = new Dictionary<string, object>();
    sauceOptions["username"] = sauceUserName;
    sauceOptions["accessKey"] = sauceAccessKey;
    sauceOptions["name"] = TestContext.CurrentContext.Test.Name;

    options.AddAdditionalCapability("sauce:options", sauceOptions);

    Driver = new RemoteWebDriver(new Uri("http://ondemand.saucelabs.com:80/wd/hub"), options.ToCapabilities(),
        TimeSpan.FromSeconds(600));
    Driver.Navigate().GoToUrl("https://www.google.com");
    Assert.Pass();
}
