A test case for Gem::Installer
.
Creates the following instance variables:
a spec named 'a', intended for regular installs
a spec named 'b', intended for user installs
the path to a built gem from @spec
the path to a built gem from @user_spec
a Gem::Installer
for the @spec that installs into @gemhome
a Gem::Installer
for the @user_spec that installs into Gem.user_dir
# File rubygems/installer_test_case.rb, line 86 def setup super @spec = quick_gem 'a' do |spec| util_make_exec spec end @user_spec = quick_gem 'b' do |spec| util_make_exec spec end util_build_gem @spec util_build_gem @user_spec @gem = @spec.cache_file @user_gem = @user_spec.cache_file @installer = util_installer @spec, @gemhome @user_installer = util_installer @user_spec, Gem.user_dir, :user Gem::Installer.path_warning = false end
The path where installed executables live
# File rubygems/installer_test_case.rb, line 112 def util_inst_bindir File.join @gemhome, "bin" end
Creates an installer for spec
that will install into gem_home
. If user
is true a user-install will be performed.
# File rubygems/installer_test_case.rb, line 179 def util_installer(spec, gem_home, user=false) Gem::Installer.at(spec.cache_file, :install_dir => gem_home, :user_install => user) end
Adds an executable named “executable” to spec
with the given shebang
.
The executable is also written to the bin dir in @tmpdir and the installed gem directory for spec
.
# File rubygems/installer_test_case.rb, line 122 def util_make_exec(spec = @spec, shebang = "#!/usr/bin/ruby") spec.executables = %w[executable] spec.files << 'bin/executable' exec_path = spec.bin_file "executable" write_file exec_path do |io| io.puts shebang end bin_path = File.join @tempdir, "bin", "executable" write_file bin_path do |io| io.puts shebang end end
Builds the @spec gem and returns an installer for it. The built gem includes:
