1) Mongoid::Clients::Options.with when passing some options when passing a block when the options create a new cluster disconnects the new cluster when the block exits
  Failure/Error: expect(connections_after).to eq(connections_before)
       expected: 4
       got: 5
  (compared using ==)

1) Mongoid::Config when discriminator_key override is not set in the config has the value _type by default
Failure/Error: expect(Mongoid::Config.discriminator_key).to be("_type")
  expected #<String:60724> => "_type"
       got #<String:60728> => "_type"
  Compared using equal?, which compares object identity,
  but expected and actual are not the same object. Use
  `expect(actual).to eq(expected)` if you don't care about
  object identity in this example.
