Answer 1

I ran into my own error again !!, when executing rake test, but in this case thanks to cedricdlb I've found here the solution, quite simply:

rake db:test:prepare
rake db:test:load

Answer 2

I have the same problem and I found that in my migrations I don't have table names in plural form:

For example:

    class CreatePosts  ActiveRecord::Migration
      def change
        create_table :posts do |t|
          t.string :source
          t.string :destination
          t.datetime :time
          t.timestamps
        end
      end
    end

I have create_table :post, but when I change it to create_table :posts. It start working!!!!
