If I want to create and instance using "create" build strategy and then want to use "attributes_for" build strategy for verification, is it possible to do? And if I use sequences in the factory? Is it possible in Machinist gem?
Not quite sure I fully understand. And I'm not a user of machinist. But it sounds like you just want to do something like this.
@attributes = FactoryGirl.attributes_for(:my_object)
my_object = MyObject.create(@attributes)
my_object.some_property.should == @attributes[:some_property]
