- 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'
f.clear
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.
