Check browser console output on Ruby

Question

How can I check a browser console for errors?

For example, I have raised browser(chrome of firefox) with Selenium and I have done some actions with Selenium WebDriver. After than I want to know is there any error in the web console.

Answer 1

I tried to take console error like:

def check_console_log
    console_log = @browser.driver.manage.get_log(:browser)
    if console_log != nil
      raise(console_log)
    end
end

and also log it to file

def write_log(file_path)
    work_log = @browser.driver.manage.get_log(:browser)
    messages = ""
    work_log.each { | item | messages += item.message + "\n"}
    File.write( "#{file_path}.log", messages ) unless messages == ""
end
