class Gem::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.
Public Class Methods
Returns the path to the certificate named cert_name
from
test/rubygems/
.
# File lib/rubygems/test_case.rb, line 1449 def self.cert_path cert_name if 32 == (Time.at(2**32) rescue 32) then cert_file = File.expand_path "../../../test/rubygems/#{cert_name}_cert_32.pem", __FILE__ return cert_file if File.exist? cert_file end File.expand_path "../../../test/rubygems/#{cert_name}_cert.pem", __FILE__ end
Returns the path to the key named key_name
from
test/rubygems
# File lib/rubygems/test_case.rb, line 1475 def self.key_path key_name File.expand_path "../../../test/rubygems/#{key_name}_key.pem", __FILE__ end
Loads certificate named cert_name
from
test/rubygems/
.
# File lib/rubygems/test_case.rb, line 1437 def self.load_cert cert_name cert_file = cert_path cert_name cert = File.read cert_file OpenSSL::X509::Certificate.new cert end
Loads an RSA private key named key_name
with
passphrase
in test/rubygems/
# File lib/rubygems/test_case.rb, line 1464 def self.load_key key_name, passphrase = nil key_file = key_path key_name key = File.read key_file OpenSSL::PKey::RSA.new key, passphrase end
Returns the make command for the current platform. For versions of Ruby built on MS Windows with VC++ or Borland it will return 'nmake'. On all other platforms, including Cygwin, it will return 'make'.
# File lib/rubygems/test_case.rb, line 1169 def self.make_command ENV["make"] || ENV["MAKE"] || (vc_windows? ? 'nmake' : 'make') end
Allows tests to use a random (but controlled) port number instead of a hardcoded one. This helps CI tools when running parallels builds on the same builder slave.
# File lib/rubygems/test_case.rb, line 1202 def self.process_based_port @@process_based_port ||= 8000 + $$ % 1000 end
Finds the path to the Ruby executable
# File lib/rubygems/test_case.rb, line 1235 def self.rubybin ruby = ENV["RUBY"] return ruby if ruby ruby = "ruby" rubyexe = "#{ruby}.exe" 3.times do if File.exist? ruby and File.executable? ruby and !File.directory? ruby return File.expand_path(ruby) end if File.exist? rubyexe and File.executable? rubyexe return File.expand_path(rubyexe) end ruby = File.join("..", ruby) end begin require "rbconfig" File.join(RbConfig::CONFIG["bindir"], RbConfig::CONFIG["ruby_install_name"] + RbConfig::CONFIG["EXEEXT"]) rescue LoadError "ruby" end end
Returns whether or not we're on a version of Ruby built with VC++ (or Borland) versus Cygwin, Mingw, etc.
# File lib/rubygems/test_case.rb, line 1152 def self.vc_windows? RUBY_PLATFORM.match('mswin') end
Is this test being run on a Windows platform?

minimum of extra work. name
and version
are the
gem's name and version, platform, author, email, homepage, summary and
description are defaulted. The specification is yielded for customization.

setup prepares a sandboxed location to install gems. All installs are directed to a temporary directory. All install plugins are removed.
If the RUBY
environment variable is set the given path is used
for Gem.ruby. The local platform
is set to i386-mswin32
for Windows or
i686-darwin8.10.1
otherwise.
If the KEEP_FILES
environment variable is set the files will
not be removed from /tmp/test_rubygems_#{$$}.#{Time.now.to_i}

Creates a SpecFetcher pre-filled with the gems or specs defined in the block.
Yields a fetcher
object that responds to spec
and
gem
. spec
adds a specification to the
SpecFetcher while gem
adds both a specification and the gem
data to the RemoteFetcher so the built gem can be downloaded.
If only the a-3 gem is supposed to be downloaded you can save setup time by creating only specs for the other versions:
spec_fetcher do |fetcher| fetcher.spec 'a', 1 fetcher.spec 'a', 2, 'b' => 3 # dependency on b = 3 fetcher.gem 'a', 3 do |spec| # spec is a Gem::Specification # ... end end

Sets up a fake fetcher using the gems from util_make_gems.
Optionally additional prerelease
gems may be included.
Gems created by this method may be fetched using Gem::RemoteFetcher.

Sets up Gem::SpecFetcher to return
information from the gems in specs
. Best used with +@all_gems+
from util_setup_fake_fetcher.

Creates a spec with name
, version
.
deps
can specify the dependency or a block
can be
given for full customization of the specification.
# File lib/rubygems/test_case.rb, line 829 def util_spec name, version = 2, deps = nil # :yields: specification raise "deps or block, not both" if deps and block_given? spec = Gem::Specification.new do |s| s.platform = Gem::Platform::RUBY s.name = name s.version = version s.author = 'A User' s.email = 'example@example.com' s.homepage = 'http://example.com' s.summary = "this is a summary" s.description = "This is a test description" yield s if block_given? end if deps then # Since Hash#each is unordered in 1.8, sort the keys and iterate that # way so the tests are deterministic on all implementations. deps.keys.sort.each do |n| spec.add_dependency n, (deps[n] || '>= 0') end end Gem::Specification.reset return spec end
Deflates data
# File lib/rubygems/test_case.rb, line 1099 def util_zip(data) Zlib::Deflate.deflate data end
Construct a new Gem::Version.

Returns whether or not we're on a version of Ruby built with VC++ (or Borland) versus Cygwin, Mingw, etc.

A #vendor_gem is used with
a gem dependencies file. The gem created here has no files, just a gem
specification for the given name
and version
.
Yields the specification
to the block, if given
# File lib/rubygems/test_case.rb, line 1346 def vendor_gem name = 'a', version = 1 directory = File.join 'vendor', name FileUtils.mkdir_p directory save_gemspec name, version, directory end
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).

Is this test being run on a Windows platform?
# File lib/rubygems/test_case.rb, line 1144 def win_platform? Gem.win_platform? end
Writes a binary file to path
which is relative to +@gemhome+
# File lib/rubygems/test_case.rb, line 609 def write_file(path) path = File.join @gemhome, path unless Pathname.new(path).absolute? dir = File.dirname path FileUtils.mkdir_p dir unless File.directory? dir File.open path, 'wb' do |io| yield io if block_given? end path end
