Given the following file
Modified from

require ‘test/unit’
class TestTest < Test::Unit::TestCase
def test_one

and Ruby 1.9.3
$ /usr/bin/ruby1.9.1 --version

I’m able to run tests non-parallelized:
$ /usr/bin/ruby1.9.1 replication.rb
Run options:
Running tests:
…
Finished tests in 0.000458s, 4368.4051 tests/s, 4368.4051 assertions/s.
2 tests, 2 assertions, 0 failures, 0 errors, 0 skips
But not in parallel:
$ /usr/bin/ruby1.9.1 replication.rb --jobs=2 --ruby /usr/bin/ruby1.9.1
Run options: --jobs=2 --ruby /usr/bin/ruby1.9.1
Running tests:
Retrying…
Finished tests in 0.037315s, 0.0000 tests/s, 0.0000 assertions/s.
0 tests, 0 assertions, 0 failures, 0 errors, 0 skips
I’ve also found this to be the case on both Ubuntu (12.04) and OS X
(snow leopard).
Do I need to be using rake in order to do parallel testing? Or have I
done something else wrong?
Thanks,
