Datamapper DataMapper

I have in my Gemfile both dm-mysql-adapter and dm-sqlite-adapter. First for prod/dev and sqlite for speedy tests. I load them using bundler and now when I run tests even though I specifically setup with DataMapper.setup(:default, "sqlite::memory:") it tries to connect somewhere else using some default rules with root@localhost. My code runs after I comment out dm-mysql-adapter from Gemfile.

Gemfile has

gem 'datamapper', '1.1.0'
gem 'dm-mysql-adapter', '1.1.0'
gem 'dm-sqlite-adapter', '1.1.0'

I setup them with

Bundler.setup
DataMapper.setup(:default, "sqlite::memory:")

Expected behaviour

Datamapper would connect to in memory sqlite database

What really happens

DataObjects::ConnectionError: Access denied for user 'root'@'localhost' (using password: NO)
