Abstract
Class temporal specification is a kind of important program specifications, which specifies that methods of a class should be called in a particular sequence. Dynamic specification mining is a promising approach to achieve this kind of specifications automatically. However, they always infer partial specifications, that is, the mined specifications are biased to input programs or program execution traces. In this paper, we propose to mine class temporal specifications based on a probabilistic model in an online mode. Since our method can evolve mined specifications persistently, universal specifications can be achieved. To investigate our technique's feasibility and effectiveness, we implemented it in a prototype tool ISpecMiner and used the tool to perform experiments. Experimental results show that our method is promising to infer universal specifications if sufficient traces are provided for mining.
