rake spec runs test after specs

Question

When I run rake spec in my Rails project it executes all specs and then tries to run tests (like rake test):

$ rake spec
ruby -S rspec ./spec/... #file list
# --> ...  normal RSpec output
Finished in 11.11 seconds
111 examples, 0 failures, 11 pending

# --> here starts the problem <--
Run options: 

# Running tests:

Finished tests in 0.000343s, 0.0000 tests/s, 0.0000 assertions/s.
0 tests, 0 assertions, 0 failures, 0 errors, 0 skips

Do you know, why it tries to run Test::Unit tests even though I have none of them? (I don't even have test/ directory)

EDIT: When I run other rake commands, they do their job but then they finish with error, for example:

What does your Rakefile look like? and maybe your Gemfile too. — Vincent B.
Rakefile simply requires config/application and runs load_tasks. There is nothing about the Test::Unit in the Gemfile, should I look for anything special? — mrzasa
I also have this issue. But if I run rake notes I don't see the problem. I think it is only related to tasks that have depends on environment task such as task :about => [:environment], could you try with rake notes? — Jarl
What did you do since you suddenly started experiencing this annoying behaviour? — Jarl
I had those problems a while ago. After that I reisntalled my system (for other reasons) and now it's OK I think... — mrzasa

Any file with require test/unit enables an at_exit hook which attempts to run tests.

If any file loaded from your rake task does this, the at_exit hook tries to run the test using the last part of your rake command as the name of the test to run. In the case of rake about, it searches for a test named about which doesn't exist.

I had the problem when I had shoulda gem in my Gemfile. I solved it by including this in the Gemfile :

gem 'test-unit', :require => "test/unit"

rake spec runs test after specs
