MiniTest::Unit::TestCase
RubyGemTestCase provides a variety of methods for testing rubygems and gem-related behavior in a sandbox. Through RubyGemTestCase you can install and uninstall gems, fetch remote gems through a stub fetcher and be assured your normal set of gems is not affected.
Tests are always run at a safe level of 1.
Returns the path to the certificate named cert_name from

In case we’re building docs in a background process, this method waits for that process to exit (or if it’s already been reaped, or never happened, swallows the Errno::ECHILD error).
# File rubygems/test_case.rb, line 870
def wait_for_child_process_to_exit
Process.wait if Process.respond_to?(:fork)
rescue Errno::ECHILD
end
Is this test being run on a Windows platform?
# File rubygems/test_case.rb, line 822
def win_platform?
Gem.win_platform?
end
Writes a binary file to path which is relative to +@gemhome+
# File rubygems/test_case.rb, line 357
def write_file(path)
path = File.join @gemhome, path unless Pathname.new(path).absolute?
dir = File.dirname path
FileUtils.mkdir_p dir
open path, 'wb' do |io|
yield io if block_given?
end
path
