sqilte3 test-case issue

Hi, there:
   My environment: rails 2.02, sqlite3, ruby 1.8.6
   I am stucked at my first test-case running. Everything about
database works fine in development environment. however, I ran "rake
db:test:prepare" and then I tried the default generated test-case, it
errors as follow. I checked in test.sqlite3, the table does exist
(and all blank).
   Any clues? Thanks in advance!


I am having the same problem as you are, I have two tables and cannot
unit test either of them. Can anyone help?
