RSpec failure: could not find table after migration...?

I have a naked rails 3 app with one model, generated using rails g model User.

I've added a factory (using factory_girl_rails):

Factory.define :user do |f|
  f.email "[email protected]"
  f.password "blah"
  f.password_confirmation "blah"
  f.display_name "neezer"
end

Then I've added one test:

require 'spec_helper'

describe User do

  subject { Factory :user }

  it "can be created from a factory" do
    subject.should_not be_nil
    subject.should be_kind_of User
  end

end

Then I migrate my database using rake db:migrate.

Then I run the test using rspec spec, and the test fails with the following:

Failures:

  1) User can be created from a factory
     Failure/Error: subject { Factory :user }
     ActiveRecord::StatementInvalid:
       Could not find table 'users'
     # ./spec/models/user_spec.rb:5:in `block (2 levels) in <top (required)>'
     # ./spec/models/user_spec.rb:8:in `block (2 levels) in <top (required)>'

I'm confused, because I did just migrate my database, and my schema.db file reflects that there is a users table present, so what gives?

I know this is a beginner question, but banging my head against a wall isn't working...

factory_girl (1.3.3)
factory_girl_rails (1.0.1)
rails (3.0.5)
rspec-rails (2.5.0)
sqlite3 (1.3.3)

try this out:

For rails version > 4.1+ this solution will work as the current scenario.

but in Rails 4.1+, rake db:test:prepare is deprecated.

try using

rake db:migrate RAILS_ENV=test (it will work for all version of rails)

The point here is that rspec command doesn't execute migrations on your test database. and rake db:migrate only runs migrations in your current environment, probably development. Others environment like production and test ends without having those changes.

You can run 

rake spec

That will prepare your testing db (drop and create using schema.rb) and run all tests.

As the other answer suggested, this:

rake db:test:prepare

Will also setup your testing db, but you have to run the rspec command after that, so, personally I prefer the first option.

Try to execute 

rake db:test:prepare

This should fix your tests db.
