Creates the following instance variables:
- @spec
-
a spec named ‘a’, intended for regular installs
And returns a gem built for the @spec

util_installer @spec, @gemhome
end
Creates the following instance variables:
- @spec
-
a spec named ‘a’, intended for regular installs
- @gem
-
the path to a built gem from @spec
And returns a Gem::Installer for the @spec that installs into @gemhome

def setup_base_spec
quick_gem 'a' do |spec|

end
Sets up a generic specification for testing the rubygems installer
And returns it

end

end
Creates the following instance variables:
- @spec
-
a spec named ‘a’, intended for regular installs
- @user_spec
-
a spec named ‘b’, intended for user installs
- @gem
-
the path to a built gem from @spec
- @user_gem
-
the path to a built gem from @user_spec
And returns a Gem::Installer for the @user_spec that installs into Gem.user_dir

The path where installed executables live

def util_installer(spec, gem_home, user=false)
Gem::Installer.at(spec.cache_file,
:install_dir => gem_home,
:user_install => user)
end
Creates an installer for spec that will install into gem_home. If user is true a user-install will be performed.
# File tmp/rubies/ruby-2.7.6/lib/rubygems/installer_test_case.rb, line 88
def util_make_exec(spec = @spec, shebang = "#!/usr/bin/ruby", bindir = "bin")

io.puts shebang
end
bin_path = File.join @tempdir, "bin", "executable"
write_file bin_path do |io|
io.puts shebang
end
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.

Builds the @spec gem and returns an installer for it. The built gem includes:
bin/executable lib/code.rb ext/a/mkrf_conf.rb

end
Sets up the base @gem, builds it and returns an installer for it.
