Inherits: | Object |
Defined in: | lib/rubygems/test_utilities.rb |
Overview
A fake RemoteFetcher for use in tests or to avoid real live HTTP requests when testing code that uses RubyGems.
Example:
@fetcher = Gem::FakeFetcher.new
@fetcher.data['http://gems.example.com/yaml'] = source_index.to_yaml
Gem::RemoteFetcher.fetcher = @fetcher
# invoke RubyGems code
paths = @fetcher.paths
assert_equal 'http://gems.example.com/yaml', paths.shift
assert paths.empty?, paths.join(', ')
See RubyGems' tests for more examples of FakeFetcher
