tests: switch to minitest

[ktdreyer]

Ruby 1.9+ uses Minitest as the backend for Test::Unit. As of Minitest 5, the shim no longer supports Test::Unit::TestCase.

Adjust the svn2git test suite to support Minitest 5's syntax.

Minitest versions 4 and below do not support the newer Minitest::Test class that arrived in version 5. For that case, use the MiniTest::Unit::TestCase class as a fallback.

Thanks. I've just gotten a chance to look at this and it looks pretty good. I need to make a slight modification to get the tests running on 1.8. It appears that require 'test/unit' would implicitly require 'rubygems', whereas require 'minitest/autorun' will not. This isn't a problem on 1.9+ because rubygems is always loaded.

Thanks for the patch review.

I've amended the original commit 3e25ed8 to 85106f7 . I've added require 'rubygems' and I've rebased onto master. With this change, I've confirmed that rake test passes on CentOS 6 (ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux])

Thanks for the quick turnaround. I was just informing you why I hadn't merged it yet -- I was planning on fixing it up myself. But this is even better :-)

I tested in 1.8.7-p375, 2.1.2p95, and JRuby 1.7.12 (1.9 mode). It seems to check out everywhere. Now I just need to get more tests in there :-/

Cool, thanks for merging :)
