Abstract

The present paper presents an overview of the main results of the ASTEC project Verication of Erlang Programs, focusing in particular on the Erlang verication tool. This is a theorem-proving tool which assists in obtaining proofs that Erlang applications satisfy their correctness requirements formulated in a specication logic. We give a summary of the verication framework as supported by the tool, discuss reasoning principles essential for successful verication such as inductive and compositional reasoning, and an ecient treatment of side-eect-free code. The experiences of applying the verication tool in an industrial case study are summarised, and an approach for supporting verication in the presence of program libraries is outlined. The verication tool is essentially a classical proof assistant, or theoremproving tool, requiring users to intervene in the proof process at crucial steps such as stating program invariants. However, the tool oers considerable su...
