Overview

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.

.make_command ⇒ Object

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’.

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.

Creates a Gem::Specification with a 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.

The gem is added to the installed gems in @gemhome and to the current source_index.

Use this with #write_file to build an installed gem.

#setup ⇒ Object

#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}.

#util_make_gems(prerelease = false) ⇒ Object

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

TODO: nuke this and fix tests. this should speed up a lot

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.
