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

cert_path(cert_name) click to toggle source

Returns the path to the certificate named cert_name from test/rubygems/.

 
               # File rubygems/test_case.rb, line 1070
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
            
key_path(key_name) click to toggle source

Returns the path tot he key named key_name from test/rubygems

 
               # File rubygems/test_case.rb, line 1096
def self.key_path key_name
  File.expand_path "../../../test/rubygems/#{key_name}_key.pem", __FILE__
end
            
load_cert(cert_name) click to toggle source

Loads certificate named cert_name from test/rubygems/.

 
               # File rubygems/test_case.rb, line 1058
def self.load_cert cert_name
  cert_file = cert_path cert_name

  cert = File.read cert_file

  OpenSSL::X509::Certificate.new cert
end
            
load_key(key_name) click to toggle source

Loads an RSA private key named key_name in test/rubygems/

 
               # File rubygems/test_case.rb, line 1085
def self.load_key key_name
  key_file = key_path key_name

  key = File.read key_file

  OpenSSL::PKey::RSA.new key
end
            
make_command() click to toggle source

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’.

process_based_port() click to toggle source

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.

  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
            
vc_windows?() click to toggle source

def self.vc_windows?
  RUBY_PLATFORM.match('mswin')
end

Is this test being run on a Windows platform?

 
               # File rubygems/test_case.rb, line 879

end
            
util_build_gem(spec) click to toggle source

Builds a gem from spec and places it in File.join @gemhome, 'cache'. Automatically creates files based on spec.files

 
               # File rubygems/test_case.rb, line 504
def util_build_gem(spec)
  dir = spec.gem_dir
  FileUtils.mkdir_p dir

  Dir.chdir dir do

    cache = spec.cache_file
    FileUtils.mv File.basename(cache), cache
  end
end
            
util_clear_gems() click to toggle source

Removes all installed gems from +@gemhome+.

util_gem(name, version, deps = nil, &block) click to toggle source

Creates a gem with name, version and deps. The specification will be yielded before gem creation for customization. The gem will be placed in File.join @tempdir, 'gems'. The specification and .gem file location are returned.

 
               # File rubygems/test_case.rb, line 658
def util_gem(name, version, deps = nil, &block)

      # 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|

  end

  out.string
end
            
util_make_gems(prerelease = false) click to toggle source

Creates several default gems which all have a lib/code.rb file. The gems are not installed but are available in the cache dir.

+@a1+

gem a version 1, this is the best-described gem.

+@a2+

gem a version 2

+@a3a

gem a version 3.a

+@a_evil9+

gem a_evil version 9, use this to ensure similarly-named gems don’t collide with a.

+@b2+

gem b version 2

+@c1_2+

gem c version 1.2

+@pl1+

gem pl version 1, this gem has a legacy platform of i386-linux.

Additional prerelease gems may also be created:

+@a2_pre+

gem a version 2.a

This line is really, really long.  So long, in fact, that it is more than eighty characters long!  The purpose of this line is for testing wrapping behavior because sometimes people don't wrap their text to eighty characters.  Without the wrapping, the text might not look good in the RSS feed.

Also, a list:
  * An entry that\'s actually kind of sort
  * an entry that\'s really long, which will probably get wrapped funny.  That's ok, somebody wasn't thinking straight when they made it more than eighty characters.

util_setup_fake_fetcher(prerelease = false) click to toggle source

Sets up a fake fetcher using the gems from util_make_gems. Optionally additional prerelease gems may be included.

wait_for_child_process_to_exit() click to toggle source

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 934
def wait_for_child_process_to_exit
  Process.wait if Process.respond_to?(:fork)
