I misunderstood your initial example, thinking that NameBuilder required an initializer w/ two args. I'd use a factory pattern here: def new_foo(arg1=nil,arg2=nil) Foo.new(arg1,arg2) end def new_bar(arg=nil) Bar.new(arg) end Now you can use these without arguments when you want to: describe Foo do it_behaves_like "a nameable thingie", new_foo end describe Bar do it_behaves_like "a nameable thingie", new_bar end And you can use the with arguments as well: it "does something else" do foo = make_foo(x) other_foo = make_foo(x,y) end David _______________________________________________ rspec-users mailing list rspec-users@rubyforge.org http://rubyforge.org/mailman/listinfo/rspec-users
