Testing conceptually consists of three activities: test case generation, test case execution and verdict assignment. Using online testing, test cases are generated and simultaneously executed. This paper presents a framework that automatically generates and executes tests "online" for conformance testing of the Web service composition described in BPEL. The proposed framework considers unit testing and it is based on a timed modeling of BPEL specification, a distributed testing architecture and an online testing algorithm that generates, executes and assigns verdicts to every generated state in the test case.

This paper presents a methodology to perform passive testing of behavioural conformance for the web services based on the security rule. The proposed methodology can be used either to check a trace (offline checking) or to runtime verification (online checking) with timing constraints, including future and past time. In order to perform this: firstly, we use the Nomad language to define the security rules. Secondly, we propose an algorithm that can check simultaneously multi instances. After that, with each security rule, we propose a graphical statistics, with some fixed properties, that helps to tester easy assess about the service. In addition to the theoretical framework we have developed a software tool, called RV4WS (Runtime Verification engine for Web Service), that helps in the automation of our passive testing approach. In particular, the algorithm presented in this paper are fully implemented in the tool. We also present a mechanism to collect the observable trace in this paper.
