Rails 3 test database issues

I am having a problem using the test database in Rails 3. It
apparently has kept track of aspects of the database that I deleted
completely from my migrations at some point. I don't always use the
'down' part of a migration and sometimes just recreate the whole
database. I did rake db:migrate:reset and rake db:test:prepare, but
when I run my test it is trying to access tables that are not in the
test at all and fields that are not in that table.

test_attr_merge(UserSectionTest):
ActiveRecord::StatementInvalid: Mysql::Error: Unknown column
'conversion_dir_id'
in 'field list': INSERT INTO `conversions` (`file_name`,
`conversion_dir_id`, `
created_at`, `updated_at`, `id`) VALUES ('MyString', 1, '2011-07-25
13:32:52', '
2011-07-25 13:32:52', 980190962)

did you run your migrations for test environment as well?

RAILS_ENV=test rake db:migrate

?

Does rake db:test:prepare do this? I'm not sure from looking at the Guide.

No, I hadn't tried that, but I just did the following below along
with that and it is trying to access a table that maybe I had at one
time 'ingredients', but no longer have in my schema or migrations. I
guess I might like to completely destroy my databases and start over.
Not sure the easiest way to do that ..

rake db:test:prepare loads your schema.rb (or dbstructure.sql) into your
test database. I don't think that's the problem.

Looking at the stack trace, I would guess that you still have some
fixture files for tables that you have deleted.
