System rake test task doesn't run my tests

I'm sure I'm doing something naive or stupid, I'm just not sure what it is.

I'm writing a simple library for parsing data URIs. Being so simple, I figured I'd go ahead and just give ruby-1.9's minitest a whirl. The tests run great when I run them by hand, but when I try to run them with 'rake test', hoping to invoke开发者_JAVA技巧 the system rake test task, I get no joy. Specifically, with trace and verbose:

Donalds-Decisiv-MacBook-Pro:data_uri dball$ rake test -t -v
(in /Users/dball/src/data_uri)
** Invoke test (first_time, not_needed)

I've got tests in the test folder, they all start with test_ and end in .rb. Any ideas?

The repository of the project is http://github.com/dball/data_uri

Tests are not invoked because you didn't give rake any information about them.

Put this task in Rakefile:

require 'rake/testtask'
Rake::TestTask.new do |i|
  i.test_files = FileList['test/test_*.rb']
  i.verbose = true
end

Or grab a patch for your project.
