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.

#quick_gem(name, version = '2') ⇒ Object

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.

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|
