# A fake Gem::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.
