Question

When I run my rspec tests, many fail due to stale data in my mongodb database. AFAIK it is far better to test with a clean database.

With mysql, I could run rake db:test:prepare to clean up the database. How can I clean nd/or re-seed the database before each test?

If you are using MongoID you can use Database Cleaner with Truncation strategy. E.g.:

RSpec.configure do |config|
  config.use_transactional_fixtures = false

  config.before :each do
    DatabaseCleaner.strategy = :truncation
    DatabaseCleaner.start
  end

  config.after do
    DatabaseCleaner.clean
  end
end
