....proof, and then progressively refine it into an implementation, which is tested. The Cogito development methodology [3, 23] is one such method. It has tool support for each stage of the formal development process, except the role of testing in Cogito is not discussed. An animator called Possum [11, 12] is used in Cogito to test the specification before refinement begins. The B Method is another formal development methodology. B uses an animator to test specifications before development. Waeselynck and Behnia [33] argue that in B, animation should be performed not only at the specification ....
....section, we present the Possum animation tool, which we use to animate Sum specifications, and PGMGEN, which we use to generate test drivers for C modules. The method presented in Section 4 uses Possum and PGMGEN to combine specification animation and implementation testing. 3. 1 Possum Possum [11, 12] is an animation tool for Z and Z like specification languages, including Sum [21] Possum interprets queries made in Sum and responds with simplifications of those queries. For example, the query: fx, y : 0 . 60 x 13 = y 11g is simplified by Possum to: f(0,0) 11,13) 22,26) 33,39) ....

A variety of model finders have been developed for group theoretic investigations [eg, 33] these work on a logic of uninterpreted functions, and do not handle relations or closure. Several animators for Z have been developed using Prolog as an underlying engine [11,12, 24,43], but these cannot handle large spaces.Most other tools for relational notations are less automatic. Theorem provers (such as Z Eves [7] and PVS [28] can unlike the Alloy Analyzer prove theorems, but do not generate counterexamples, and need help with lemmas and proof strategy. Execution ....

The Possum tool [20] has a wide variety of modes for animating specifications from animation scripts written by system analysts. For example, it can step through operational scenarios by applying operations one by one under interactive control, or it can perform complete searches of function spaces checking for ....
