Rails3 ActiveRecord::StatementInvalid:... no such table in every test

Question

I've started learning rails3 few days ago, and since today, every time I run unit test for my model I get this error message:

ActiveRecord::StatementInvalid: SQLite3::SQLException: no such table: users: DELETE FROM "users" WHERE 1=1

The tests went smoothly yesterday, I run them today (reverting everything to the state from the time they were working)... and I'm still getting the error.

I'm using rails 3 release on Windows7 64 bit, SQLite 3.7.2, ruby 187 (but I do have many ruby installations - using pik to select 187)

Any ideas on fixing this issue?

If you created the model using a rails generator, you may have left over fixture files that are trying to access a table that isn't there anymore. For me, deleting the yml file solved the issue.

It would be worth checking that your test database is set up correctly using the schema from your development database. You can achieve this with:

rake db:test:prepare
