Interacting with browser logs using C# Selenium

Is it possible to extract browser logs in C# using selenium?

I want to document any JavaScript errors that show up on a specific webpage, ideally on Chrome or Firefox.

I've managed to do this before with Python, but I'm wondering if it's achievable in C# as well.

Answer ā„–1

For setting up and retrieving log entries using Selenium, Chrome, and C#:

ChromeOptions options = new ChromeOptions();
options.SetLoggingPreference(LogType.Browser, LogLevel.Warning);

var driver = new ChromeDriver(options);

driver.Navigate().GoToUrl("http://stackoverflow.com");

var entries = driver.Manage().Logs.GetLog(LogType.Browser);
foreach (var entry in entries) {
    Console.WriteLine(entry.ToString());
}

And for Firefox:

FirefoxOptions options = new FirefoxOptions();
options.SetLoggingPreference(LogType.Browser, LogLevel.Warning);

var driver = new FirefoxDriver(options);

driver.Navigate().GoToUrl("http://stackoverflow.com");

var entries = driver.Manage().Logs.GetLog(LogType.Browser);
foreach (var entry in entries) {
    Console.WriteLine(entry.ToString());
}
