Defined in:
lib/rubygems/test_utilities.rb

Overview

The SpecFetcherSetup allows easy setup of a remote source in RubyGems tests:

spec_fetcher do |f|
  f.gem  'a', 1
  f.spec 'a', 2
  f.gem  'b', 1' 'a' => '~> 1.0'
end

The above declaration creates two gems, a-1 and b-1, with a dependency from b to a. The declaration creates an additional spec a-2, but no gem for it (so it cannot be installed).

After the gems are created they are removed from Gem.dir.

#download(name, version, dependencies = nil, &block) ⇒ Object

Creates a gem with name, version and deps. The created gem is downloaded in to the cache directory but is not installed

The specification will be yielded before gem creation for customization, but only the block or the dependencies may be set, not both.
