test-loop - Continuous testing for Ruby with fork/eval
            https://github.com/sunaku/test-loop#readme


What is it?
-----------

test-loop is a fast continuous testing tool for Ruby that automatically
detects and tests changes in your application in an efficient manner:

1. Absorbs the test execution overhead into the main Ruby process.
2. Forks to run your test files without overhead and in parallel.
3. Avoids running unchanged test blocks inside changed test files.


What is new?
------------

### Version 12.3.0 (2011-07-19)

New features:

* Add `Test::Loop::max_concurrent_tests` configuration parameter to
  limit the number of test files run concurrently (default 4).
  Otherwise, with large test suites, we could end up swamping the
  machine running the tests by forking hundreds of test files at
  once.  (Jacob Helwig)

* Rails: add matcher for test/factories/*_factory.rb.

Housekeeping:

* ENV returns a Hash with duplicate/frozen keys/values.
  (Brian D. Burns)

* Use Marshal to propagate resume_files to reabsorb.

* Store test_files in a Set instead of an Array.
