DatabaseCleaner doesn't seem to clean between suits

saviors.

I'm having a trouble with cleaning database after each RSpec example. The thing is, that when I run rspec command, users_controller_spec.rb complains that there are more records than the example expects. Indeed the records are being created as it says if I check with rails c. when I run the this suite alone, it will be successful, so I assume it is because DatabaseCleaner doesn't clean the user records which other specs create(the number of user records matches the extra records users_controller_spec example claims to be). They are created in before :all block(if that matters).

Here is my rails_helper.rb

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV['RAILS_ENV'] ||= 'test'
require 'spec_helper'
require File.expand_path('../../config/environment', __FILE__)
require 'rspec/rails'

# Add additional requires below this line. Rails is not loaded until this point!
require 'devise'
require 'admin/v1/dashboard_controller'
# Requires supporting ruby files with custom matchers and macros, etc, in
Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }

# Checks for pending migrations before tests are run.
# If you are not using ActiveRecord, you can remove this line.
ActiveRecord::Migration.maintain_test_schema!

RSpec.configure do |config|
  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  config.include Devise::Test::ControllerHelpers, type: :controller
  config.include ControllerMacros, type: :controller
  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  config.include FactoryGirl::Syntax::Methods

  config.infer_spec_type_from_file_location!

  config.before(:suite) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
  end

  config.around(:each) do |example|
    DatabaseCleaner.cleaning do
      example.run
    end
  end
end

users_controller.rb

describe 'GET #index' do
  it 'populates an array of users' do
    user1 = create(:user)
    user2 = create(:user)
    get :index
    expect(assigns(:users)).to match_array([user1, user2])
  end
  it 'renders :index template' do
    get :index, {}
    expect(response).to render_template :index
  end
end
