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

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'.

# File lib/rubygems/test_case.rb, line 1247
def self.make_command
  ENV["make"] || ENV["MAKE"] || (vc_windows? ? 'nmake' : 'make')
end
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.

# File lib/rubygems/test_case.rb, line 1280
def self.process_based_port
  @@process_based_port ||= 8000 + $$ % 1000
end
rubybin() click to toggle source

Finds the path to the Ruby executable

# File lib/rubygems/test_case.rb, line 1313
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
vc_windows?() click to toggle source

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 1230
def self.vc_windows?
  RUBY_PLATFORM.match('mswin')
end
win_platform?() click to toggle source

Is this test being run on a Windows platform?

setup() click to toggle source

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}.
