C# Selenium webdriver JavaScript errors logging

Question

I'm testing with Selenium webdriver using C#. How can I log all JavaScript errors that could happen through my tests?

Answer 1

That depends what you mean, if you want to capture javascript errors generated in your code when you use:

((IJavaScriptExecutor)_driver).ExecuteScript("some javascript code here")

Then just wrap those statements in a try/catch/finally and log the exception.

If you want to capture javascript errors generated by the browser, then the short answer is: you can't easily do so.

The long answer:

1. Use the Firefox driver
2. Instantiate it with a custom profile
3. install the Firebug and ConsoleExport plugins
4. Appropriately configure those plugins via SetPreference() so that it will automatically export the console to a location of your choice

If you need some sample code, let me know and I'll give you the really long answer...
