We are facing issue when we are executing the scenarios in cucumber ruby using Capybara. After few Scenarios are executed, we are getting time out error and not able to proceed to next scenario.
Following error is displayed
Timeout::Error (Timeout::Error)

We are using Capybara 2.1.0 version and Cucumber 1.3.8.
Any ideas would be greatly appreciated!

I am using ruby to collect METAR and TAF data from the Aviation Weather Center.
Their API is https://aviationweather.gov/adds/dataserver
I am using rest client
My code looks like this:
require 'nokogiri'
require 'rest-client'
url = 'https://aviationweather.gov/adds/dataserver_current/httpparam?dataSource=metars&requestType=retrieve&format=xml&stationString=KMEM&hoursBeforeNow=1'
results=RestClient.get(url)
However after doing this in the command prompt I receive an long error msg, shown below.
Am I missing any significant code in the RestClient.get?
Errno::ECONNRESET: An existing connection was forcibly closed by the remote host.

I am new bee to twitter API and MongoDb. I am trying out a ruby example from the book 'MongoDb In Action', Chapter-3 which connects to Twitter and gets feeds based on given tags. I have done the ruby set up as suggested. I am getting the following exception, which I think is related to ruby set up. Any hint is highly appreciated.

The book you are reading was printed in 2011 and appears to use APIv1 which has recently been depreciated by twitter.

You'll need to set up oauth and I suggest you start with the twitter gem documentation.

I'm facing a Timeout::Error issue while loading heavy web page. I observed that even if I added an implicit wait call #driver.manage.timeouts.implicit_wait = 300, a timeout error is thrown before 300 seconds - it's thrown in around 60-70 seconds.
Error thrown is -

try using gem fakeweb
FakeWeb is a helper for faking web requests in Ruby. It works at a global level, without modifying code or writing extensive stubs.
In GEMFILE write
gem 'fakeweb', :require => false
require 'fakeweb'
use above statement in your file
Hope this would work..
I believe the original issue isn't with Selenium and your question is answered here:
