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 Gem::Specification with a minimum of extra work. name and version are the gem’s name and version, platform, author, email, homepage, summary and description are defaulted. The specification is yielded for customization.

The gem is added to the installed gems in @gemhome and the runtime.

Use this with #write_file to build an installed gem.
