You aren't showing the full output nor the rake version nor ruby -v.

Ruby 1.9.3 preview 1 ships with rake 0.9.2.1 which does not have this bug.  See:

http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/tags/v1_9_3_preview1/lib/rake/rake_test_loader.rb?r1=32217&r2=32265

Which matches the fix from rake:

https://github.com/jimweirich/rake/commit/962ee5bae35f6e48a2ee707c974bc82fddb74c68#lib/rake/rake_test_loader.rb

I can't reproduce:

$ find . -type f
./Rakefile
./test/test_a.rb
./test/test_b.rb
$ cat Rakefile 
require 'rake/testtask'

desc "Run basic tests"
Rake::TestTask.new { |t|
 t.pattern = 'test/test_*.rb'
 t.verbose = true
 t.warning = true
}

$ cat test/test_a.rb 
require 'test/unit'

class TestA < Test::Unit::TestCase

  def test_a
    assert true
  end

end

$ cat test/test_b.rb 
require 'test/unit'

class TestB < Test::Unit::TestCase

  def test_b
    refute true
  end

end
