Run-Time Verification of Black-Box Components Using Behavioral Specifications: An Experience Report on Tool Development

We introduce a generic component-based design of a run-time checker, identify its components and their requirements, and evaluate existing state of the art tools instantiating each component

Run-Time Assertion Checking of Data- and Protocol-Oriented Properties of Java Programs: An Industrial Case Study

htmlabstractRun-time assertion checking is one of the useful techniques for detecting faults, and can be applied during any program execution context, including debugging, testing, and production. In general, however, it is limited to checking state-based properties. We introduce SAGA, a general framework that provides a smooth integration of the specification and the run-time checking of both data- and protocol-oriented properties of Java classes and interfaces. We evaluate SAGA, which combines several state-of-the art tools, by conducting an industrial case study from an eCommerce software company Fredhopper

Combining Monitoring with Run-time Assertion Checking

We develop a new technique for Run-time Checking for two object-oriented languages: Java and the Abstract Behavioral Specification language ABS. In object-oriented languages, objects communicate by sending each other messages. Assuming encapsulation, the behavior of objects is completely determined by the order of the messages, and their content. Traditional methods for Run-time Checking focus either exclusively on the description and testing of the order of the messages (Monitoring), or they focus on specifying and testing the content of those messages (Run-time Assertion Checking). Our method combines Monitoring with Run-time Assertion Checking.The basic idea behind our technique is that the behavior of objects can be described formally by means of an attribute grammar extended with assertions. The underlying (context-free) grammar specifies the valid orderings of the messages, the attributes define properties of the contents of the messages, and assertions specify the desired values of those properties. We develop a new Run-time Checker for attribute grammars in the form of a meta-program in the language Rascal and applied the Run-time Checker to an industrial case of the e-commerce company Fredhopper. We also investigated the efficiency of the run-time checker, and successfully discovered and solved several bugs in the Fredhopper software.Algorithms and the Foundations of Software technolog
