MongoidCleaner

Build Status

MongoidCleaner is an alternative for DatabaseCleaner for projects using MongoDB along with Mongoid. Besides the truncate strategy, this gem also provides faster drop strategy. It runs with Mongoid versions 4 and 5.

Why?

DatabaseCleaner always served our needs well, unfortunately it didn't support MongoDB 3 running on Wired Tiger for quite some time, so we decided to build our own specialised solution.

Also, removing all the documents from a collection requires much more work: Freeing the document's storage, clearing the index entries that point to the document, etc.. The benefit of simply dropping a collection is that it is much faster.

Possible drawbacks

We haven't experienced any problems so far, but dropping a collection will also remove the collections indexes. Feel free to report any issues related to that.

Installation

Add this line to your application's Gemfile:

gem 'mongoid_cleaner'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mongoid_cleaner

Usage

With rspec:

RSpec.configure do |config|
  config.before(:suite) do
    MongoidCleaner.strategy = :drop
  end

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

Without rspec:

MongoidCleaner.strategy = 'drop', { only: %w(users) }
MongoidCleaner.clean
# dirty mongo
MongoidCleaner.strategy = 'truncate', { except: %w(users) }
MongoidCleaner.clean
