Hello, previous version has some problems with rails 2.0.2. Following code seems to be working correctly.

Rake::TaskManager.class_eval do
  def delete_task(task_name)
    @tasks.delete(task_name.to_s)
  end
  Rake.application.delete_task("db:test:purge")
  Rake.application.delete_task("db:test:prepare")
end

namespace :db do
  namespace :test do
    task :purge => [:environment] do
      
      ActiveRecord::Base.establish_connection(ActiveRecord::Base.configurations['test'])
      ActiveRecord::Migrator.migrate("db/migrate/", 0)
      
      
    end
    
    task :prepare => [:environment, :purge] do 
      ActiveRecord::Base.establish_connection(ActiveRecord::Base.configurations['test'])
      ActiveRecord::Migration.verbose = false
      ActiveRecord::Migrator.migrate("db/migrate/")
    end
  end
end

great code sample. thanks! I don’t know if it comes from upgrading to rails 2 but I actually had to add : ActiveRecord::Base.establish_connection(ActiveRecord::Base.configurations['test'])
before the ActiveRecord::Migrator… or the reverse migration was applied to the development database instead of the test db. Anyway it helped.
