Class: Gem::TestCase::SpecFetcherSetup
- Inherits:

- Gem::TestCase::SpecFetcherSetup
- 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

. 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.
