Speeding up RSpec Tests

Hi there,

In a blog post I’ve seen that it’s really possible to speed up some of
the rspec tests by small tweaks.
As far as I understand, it is about BCrypt and the cost of encryption
algorithms.

Can anyone suggests me more techniques like that one. Because I’m
feeling that my tests are going slow while the size of my project
increases.

Regards,
Bob
