Rails - May 2007 - validates_uniqueness_of does not pass unit test

I am doing some very very basic unit testing. If I take away the
uniqueness validation, the tests pass. Could this be a bug in Edge
Rails?

Thanks,

In my model:
validates_uniqueness_of   :number, :scope => :school_id

Unit test:
def test_student_CRUD
    student = Student.new :school_id => @john.school_id, :number =>
@john.number

    assert student.save
    student_copy = Student.find(student.id)
    assert_equal student.number, student_copy.number
    student.number = "7777"
    assert student.save
    assert student.destroy
  end

Fixture:
john_doe:
  id: 1
  school_id: 1
  account_id: 1
  family_id: NULL
  first_name: John
  last_name: Doe
  number: 9999

Thanks for any help!

So what actually happens when you run this test, and what are you  
expecting it to do?

My reading says that it should fail on the first student.save line.  
(And the test will, of course, pass if you remove the uniqueness  
validation.)

You are correct, it fails on the on the save. If I remove it, it does
pass. I want it to pass with the validation.

Why does it fail on the student.save line? the number is unique as
there are no other student fixtures.
