this test took 16 minutes complete, while others, similiar took between 5-10 minutes

describe character        let(:character) { factorygirl.create :character}    describe "#add_units"           context "when unit doesnt exist beforehand"                   "it create new member"             expect(character.owns.count).to eq(0)             character.add_units("character", "archer" => 1)             expect(character.owns.count).to eq(1)             expect(character.owns.first.amount).to eq(1)         end     end 

in factory :character,

replace

 association factory: :user 

with

 association :user 

you have pass factory name i.e., :user in case , not hash factory: :user
