#database(&block) ⇒ Object

Tiny DSL for creating list or single database records via factory_bot syntax and Rspec :let or :let! methods Usage: user(:user, name: ‘Bob’) is translated to let(:user) { FactoryBot.create(:user, name: ‘Bob’) } user!(:user, name: ‘Bob’) is translated to let!(:user) { FactoryBot.create(:user, name: ‘Bob’) } user_list(:user, name: ‘Bob’, 3) is translated to let(:user) { FactoryBot.create_list(:user, 3, name: ‘Bob’) } user_list!(:user, name: ‘Bob’, 3) is translated to let!(:user) { FactoryBot.create_list(:user, 3, name: ‘Bob’) }
