Can define callbacks to run before and after all

[gabrielfalcao]

It can be defined in any file that will be imported by lettuce.

But lettuce documentation should tell to use it at terrain.py

examples:
from lettuce.terrain import before
from lettuce.terrain import after

@before.all
def populate_database(scenario):
    from my_models import Person
    Person(name="John Doe").save()

@after.all
def reset_database(scenario):
    from my_models import Person
    Person.delete_all()
