My Unit Tests are using outdated Model Data

Hello, I'm new to Rails 3 and its unit testing capabilities.

I've created a simple unit test just to see if I could get it to run correctly:

class CaseTest < ActiveSupport::TestCase   # Replace this with your real tests.   test "the truth" do     assert_equal 2,2   end end

But when I run that test with: ruby -I test test/unit/case_test.rb, it appears to be calling that unit test but is getting a Postgres insertion error on a model that I've changed awhile ago (I removed the column 'title' awhile ago and migrated which has been working fine for me in my development environment):

1.) Error: test_the_truth(CaseTest): ActiveRecord::StatementInvalid: PGError: ERROR: column "title" of relation "questions" does not exist LINE 1: INSERT INTO "questions" ("title", "body", "created_at", "upd...

I have two questions.

First, why is it even attempting to insert a new question when I'm just trying to test if 2 is the same as 2? Second, given that it is trying to insert a question for some reason, why is it using outdated model info?

Thanks for any help you can give.

Do you have a fixtures file that is being loaded automatically?

Ah, yes, that's the problem. I assumed that all the generated fixtures would be empty but I see now that Rails created some test data. And this data was from when I originally generated my models (since changed).

And I see now that, according to my Rails Unit Testing Guide: "Rails by default automatically loads all fixtures from the test/fixtures folder for your unit and functional test"

So I see it was trying to populate the db with the old table.
