Abstract : One of the early results about the asynchronous $\pi$-calculus which significantly contributed to its popularity is the capability of encoding the output prefix of the (choiceless) $\pi$-calculus in a natural and elegant way. Encodings of this kind were proposed by Honda and Tokoro, by Nestmann and (independently) by Boudol. We investigate whether the above encodings preserve De Nicola and Hennessy's testing semantics. In this sense, it turns out that, under some general conditions, no encoding of output prefix is able to preserve the must testing. This negative result is due to (a) the non atomicity of the sequences of steps which are necessary in the asynchronous $\pi$-calculus to mimic synchronous communication, and (b) testing semantics's sensitivity to divergence.
