Coverage report generated for RSpec to /home/git/gitlab/coverage. 2055 / 5187 LOC (39.62%) covered.

Here is my Gemfile:

  gem 'coveralls', require: false
  gem 'rails-dev-tweaks'
  gem 'spinach-rails', '0.2.0'
  gem "rspec-rails", '2.12.2'
  gem "capybara", '2.0.2'
  gem "pry"
  gem "awesome_print"
  gem "database_cleaner"
--
  # Generate Fake data
  gem "ffaker"

  # Guard
  gem 'guard-rspec'
  gem 'guard-spinach'

  # Notification
  gem 'rb-fsevent', require: darwin_only('rb-fsevent')

I am sure that my Gemfile do contains rspec-rails. And this command also works fine:

ruby -e 'require "webmock/rspec"'

I doubt that there is something wrong with my bundler.

But when I check my bundle.

more /usr/local/bin/bundle

I saw:

#!/usr/local/bin/ruby

This means bundle is using the same ruby as I test.

Here is the ruby version I am using:

ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-linux]

Answer 1

put this line in your GemFile

gem 'webmock'

and then do bundle install.
