无法从WebDriver获取正确的控制台日志(Chrome,C#)

我在Selenium WebDriver,C#中为Chrome浏览器编写了以下微测试(它没用,但在这里不是这样)：

[Test]
    public void T2_API_001_Printingalerts()
    {
        pgactions.OpenDataset(driver, settings.dataset); // opening page

        for (int i = 0; i < 10; i++)
        {
            ((IJavaScriptExecutor)driver).ExecuteScript("TsTable.Admin.log('this is error message', true);");
        }

        var logs = driver.Manage().Logs.GetLog(LogType.browser);

        foreach (var log in logs)
        {
            Console.WriteLine(log.ToString());
        }

        Thread.Sleep(100000);
    }

在VS中调试控制台我希望看到(就像我在Web浏览器实例中看到的WebDriver)：

randomTable.js:6711 [14:02:25.993] this is error message
randomTable.js:6711 [14:02:26.089] this is error message

但我得到的是：

------ Run test started ------

(最后一行只是重要的,但说实话 – 我甚至不能在浏览器中查看该行(？))

问题出在这一行吗？
var logs = driver.Manage().Logs.GetLog(LogType.browser); ？

我知道这一点：
https://github.com/seleniumhq/selenium-google-code-issue-archive/issues/6832

但也看到一些’黑客’以不同的方式收集错误日志.它的主要情况 – 我不需要错误,但所有日志.

有任何想法吗？

解决方法:

问题出在驱动程序声明部分,其中缺少LogLevel.现在我在[SetUp]部分设置SetLoggingPreference：

ChromeOptions options = new ChromeOptions();
options.SetLoggingPreference(LogType.browser, LogLevel.All);
driver = new ChromeDriver("path to driver", options);

并且所有日志都在调试控制台中打印:-)
