testrb (which comes with Ruby and Test::Unit) does this for you.  You  
only need to specify a directory and have your test files named  
properly (which is test_*.rb).

$ ls
test/
$ ls test
test_one.rb     test_two.rb
$ testrb test
Loaded suite test
Started
..
Finished in 0.003477 seconds.

2 tests, 2 assertions, 0 failures, 0 errors
$

If you named your tests wrong you can use the -p argument:

$ ls test
one_test.rb     two_test.rb
$ testrb test -p /_test.rb/
Loaded suite test
Started
..
Finished in 0.002296 seconds.

2 tests, 2 assertions, 0 failures, 0 errors
