Improving your test code with Wrangler
Huiqing Li, Adam Lindberg, Andreas Schumacher, Simon Thompson · Kent Academic Repository (University of Kent) · 2009
In this paper we show how the 'similar code' detection facilities of Wrangler, combined with its portfolio of refactorings, allow test code to be shrunk dramatically, under the guidance of the test engineer. This is illustrated by a sequence of refactorings of a test suite taken from an Erlang project at Ericsson AB.
