Unit tests breaks with sqlite

Hi,

I''m using an sqlite3 database with Rails and have some trouble running
unit tests

What I''ve done is
* rails my_app
* edited database.yml to use sqlite3 adapter, db/my_app_development
and db/my_app_test
* ruby script\generate model user
* edited model

    class User < ActiveRecord::Base
        validates_presence_of :name
        validates_uniqueness_of :name
    end

* edited db/migrate/001_create_users.rb migration:

    def self.up
        create_table :users do |t|
    	    t.column :name, :string, :null => false
        end
        User.create(:name => ''administrator'')
    end

* and:

    def self.down
        drop_table :users
    end

* rake db:migrate
* rake db:test:prepare

At this point, the 2 DBs are created correctly.

* rake test:units

The problem is that, but when I want to run a (any) test, I get a "SQL
logic error or missing database (SQLite3::SQLException). I can however
access the DB via the sqlite3 client/rails console without any
problem.

Here''s the exact error message I get:

I''m using Rails 1.2.3 with ruby 1.8.5, sqlite3.3.7 and sqlite3-ruby
(1.2.1)
Any help would be greatly appreciated!

Thanks in advance,

Frédéric Delanoy

Re: Unit tests breaks with sqlite

I''ve seen that "logic error" where there was a COMMIT or
ROLLBACK, but
no transaction was in flight. This is an Exception (not an Error), and
Test::Unit doesn''t catch them, unfortunately.

Somewhere within this line:
        ... 16 levels...
is your unit test code.

To debug it, modify something like execute in sqlite3/database.rb to
do the following:

rescue  Exception => e
  puts e.message
  puts e.backtrace
  raise
end

so that you can see those "16 levels".

Re: Unit tests breaks with sqlite

I''ve finally found the source of the problem: it was due to the
default fixtures in use, i.e.

first
  id: 1
second
  id: 2

After adding a (mandatory in my model) name attribute in the fixture,
like
first
  id: 1
  name: foo
second
  id:2
  name: bar

it worked.

However, what''s odd is that evenif I commented the line
  fixtures :users
in the unit test file, I had the some error.

Maybe the fixtures are used automagically ???

In all cases, thank you for your help Alexey !
