Verifying Cross-layer Interactions through Formal Model-based Assertion Generation
2019
IEEE Embedded Systems Letters
Preserved Fulltext
Our approach involves a formal model of the APIs, developed using the Event-B formal method which is automatically translated to a set of assertions and embedded in the existing implementation of APIs. ...
In this paper, we propose a formal approach to integration testing through automatic generation of runtime assertions in order to test the implementation of the APIs. ...
Our integration testing approach consists of three stages: 1) formal modelling of the framework APIs in Event-B language, 2) formal verification of consistency properties (including order of API calls ...

To face these issues, we propose a lightweight approach to runtime verification, for monitoring and failure detection of cloud computing systems. ...
We performed a preliminary evaluation of the proposed approach in the OpenStack cloud management platform, an "off-the-shelf" distributed system, showing that the approach can be applied with high failure ...

In order to address problems of modeling and verification of Web services, several process calculi have been proposed for SOAP-based Web services but none for the RESTful Web services based systems. ...
The aim of the article is to see how process calculi for SOAP-based systems deal with different aspects of their modeling domain, and whether their approaches can be used to model RESTful and ROA systems ...
The aim for the Authors was to formalize REST and ROA behavior in order to provide an automated verification of a behavior of a RESTful service. ...

Formal modelling and verification are widely used in the development of safety-critical systems. They aim at providing a mathematically-grounded argument about system safety. ...
Our approach establishes a link between safety requirements, Event-B models and corresponding fragments of a safety case. ...
In terms of Event-B, the particular system states we are interested in are usually associated with some desired post-states of specific model events. ...
