Overview
RubyGemTestCase provides a variety of methods for testing rubygems and gem-related behavior in a sandbox. Through RubyGemTestCase you can install and uninstall gems, fetch remote gems through a stub fetcher and be assured your normal set of gems is not affected.
Tests are always run at a safe level of 1.

Creates a SpecFetcher pre-filled with the gems or specs defined in the block.
Yields a fetcher
object that responds to spec
and gem
. spec
adds a specification to the SpecFetcher while gem
adds both a specification and the gem data to the RemoteFetcher so the built gem can be downloaded.
If only the a-3 gem is supposed to be downloaded you can save setup time by creating only specs for the other versions:
spec_fetcher do |fetcher|
fetcher.spec 'a', 1
fetcher.spec 'a', 2, 'b' => 3 # dependency on b = 3
fetcher.gem 'a', 3 do |spec|
# spec is a Gem::Specification
