Rspec 3.5 + factory_girl-preload are not rolling back on each test

[gustavowt]

Hy guys,

I'm trying to configure the RSpec 3.5 and factory_girl-preload 2.3.1 on Rails 5 as a usually do since Rails 2.

I just realized that something has changed on RSpec 3.5 regarding the option use_transactional_fixtures I've noticed that they are not using savepoint anymore, but are using begin/commit transactions. The problems is that, as I'm using a shared connection, every time that I change something on the database it runs a new begin/commit transaction and I'm suspecting that the rollback is not working for this case, because I'm getting some preloaded factories with different data when I run the whole suite, and the tests are running fine when I run a single suite.

Hope you guys could help here, not sure if this must be fixed on this gem or we must report this problem on the RSpec issues.
