Can't flush Mongo DB when running test

I'm using rails

, mongoid

, spork

, rspec

.

As I run tests through, rspec

I see more and more records in my database. Neither purge!

, nor database_cleaner

did they help.

My test:

describe MyConvertor do
  context 'working with my model'
    before(:each) do
      FactoryGirl.create :my_model
    end
    # examples go here
  end
end

      

        
        
        
      

    

And my helper spec:

Spork.each_run do
  RSpec.configure do |config|
    # ...
    config.before(:each) do
      Mongoid.purge!
    end
    # ...
  end
end

      

        
        
        
      

    

As I said, I also tried database_cleaner

, but nothing changed:

Spork.prefork do
  RSpec.configure do |config|
    config.order = "random"
    config.use_transactional_fixtures = false
  end
end

Spork.each_run do
  RSpec.configure do |config|
    config.before(:suite) do
      DatabaseCleaner[:mongoid].strategy = :truncation
    end

    config.before(:each) do
      DatabaseCleaner.start
    end

    config.after(:each) do
      DatabaseCleaner.clean
    end
  end
end

      

        
        
        
      

    

So, I have several questions at once: why does purge!

nothing and why DatabaseCleaner

does not work.

I found a problem with cleaning up the database , but there is no useful solution.

I use

rails 3.2.11
mongoid 3.0.23
