Capturing JavaScript error in Selenium

Question

Is there a way to capture errors occurring in the DOM in Selenium and probably flag the same as an error in the page?

To give a brief exam

Answer 1

I'm doing this to capture JavaScript errors:

[TestCleanup]
public void TestCleanup()
{
    var errorStrings = new List 
    { 
        "SyntaxError", 
        "EvalError", 
        "ReferenceError", 
        "RangeError", 
        "TypeError", 
        "URIError" 
    };

    var jsErrors = Driver.Manage().Logs.GetLog(LogType.Browser).Where(x => errorStrings.Any(e => x.Message.Contains(e)));

    if (jsErrors.Any())
    {
        Assert.Fail("JavaScript error(s):" + Environment.NewLine + jsErrors.Aggregate("", (s, entry) => s + entry.Message + Environment.NewLine));
    }
}
