Instead of calling before_create, after_build, after_create, or
after_stub, you can now call:
before(:create) {|instance| instance.name = "overridden!" }
after(:create) {|instance| instance.name = "overridden!" }
after(:build) {|instance| instance.name = "overridden!" }
after(:stub) {|instance| instance.name = "overridden!" }
Additionally, you can declare callbacks longhand:
callback(:after_stub) {|instance| instance.name = "overridden!" }
This allows for custom callbacks to be defined:
callback(:custom_callback) {|instance| instance.name = "overridden!" }
Which can then be used from a custom strategy:
class CustomStrategy
def association(runner); end
def result(evaluation)
evaluation.object.tap do |instance|
evaluation.notify(:custom_callback, instance)
end
end
end
FactoryGirl.register_strategy(:custom, CustomStrategy)
This would allow for calling:
FactoryGirl.custom(:user)
Which would return the user instance but execute the :custom_callback callback
on the user instance first.
