title: Using the seed value from rake in unit and functional tests
body: <p>When running unit and functional tests using rake, on a rails application, I notice that there is a seed value which is specified on the command line: <strong>--seed x</strong></p>
  
  <pre><code>$ rake test
  (in /code/blah)
  Loaded suite /../ruby-1.9.2-p180/gems/rake-0.8.7/lib/rake/rake_test_loader
  Started
  .
  Finished in 0.12345 seconds.
  
  1 tests, 1 assertions, 0 failures, 0 errors, 0 skips
  
  Test run options: --seed 20290
  </code></pre>
  
  <p>I assume it is possible to use this value in the tests, but I can't figure out how.
  I've tried Google, Rails Guides et al. but can't seem to find the answer.</p>
  
  <p>EDIT:</p>
  
  <p>Could this seed value be the option that is used by Minitest to randomize the execution order of tests?</p>
