Rspec =begin =end

In a file named spec/spec_helper.rb I see

See http://rubydoc.info/gems/rspec-core/RSpec/Core/Configuration

RSpec.configure do |config|

The settings below are suggested to provide a good initial experience

with RSpec, but feel free to customize to your heart’s content.

=begin

These two settings work together to allow you to limit a spec run

to individual examples or groups you care about by tagging them with

:focus metadata. When nothing is tagged with :focus, all examples

get run.

config.filter_run :focus
config.run_all_when_everything_filtered = true

.
.
.

rspec-mocks config goes here. You can use an alternate test double

library (such as bogus or mocha) by changing the mock_with option here.

config.mock_with :rspec do |mocks|
# Enable only the newer, non-monkey-patching expect syntax.
# For more details, see:
# - http://teaisaweso.me/blog/2013/05/27/rspecs-new-message-expectation-syntax/
mocks.syntax = :expect

# Prevents you from mocking or stubbing a method that does not exist on
# a real object. This is generally recommended.
mocks.verify_partial_doubles = true

end

=end
end
