Include in a minitest to restore the global configatron object to its global state afterwards. Particularly useful if you‘d like to test your application with various config settings.

```ruby class Test::Suite < Minitest::Unit

  include Configatron::Integrations::Minitest

  it 'works' do
    configatron.unlock! do
      configatron.some.setting = true
    end

    [...]
  end

```
