Can't get proper console logs from WebDriver (Chrome, C#)

Question

I wrote following micro-test (it's useless but it's not the case here) in Selenium WebDriver, C#, for Chrome browser:

[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);
    }

In debugging console in VS I expect to see (like I see in Chrome browser instance started by WebDriver):

[14:02:22.816] Settings valid!

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

but all I get is:

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

(the last line matters only, but to be honest - I can't it even see that line in browser(?))

Is the problem in this line? var logs = driver.Manage().Logs.GetLog(LogType.Browser); ?

I am aware of that: https://github.com/seleniumhq/selenium-google-code-issue-archive/issues/6832

but also saw some 'hacks' to gather error logs in different ways. The main case it - I need no errors, but ALL logs.

Any ideas?

Answer 1

The issue was in driver declaration section where LogLevel was missing. Now I set SetLoggingPreference in [SetUp] section:

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

and all logs are printed in debug console :-)
