This tutorial describes the approach we develop for the formal testing of OO software. We also describe the operational techniques, that can be used, to select test cases. ...
Reliability of today's software systems hinges on developers writing test cases that exercise as much of a program as possible. Writing and running such tests is inevitably subject to a time budget. This paper addresses the question of how to maximize qual ...
With the present day's exponential growth of the (tele-)communications market, the explosion of the number of mobile communication customers, and the tremendous growth of the number of IP hosts, ensuring the reliability of communication services is one of ...
This paper makes the case for TaaS - automated software testing as a cloud-based service. We present three kinds of TaaS: (1) a public certification service, akin to Underwriters Labs, that independently assesses the reliability, safety, and security of so ...
The boundary between programs and libraries is an appealing location for injecting faults during testing: the cost of doing so is low, and one can emulate a wide range of errors. Several tools exist, but using them faces the challenge of deciding exactly w ...

Systematic State Exploration or Model Checking techniques have been used for years to check the model of softwares against user-specified properties. Nevertheless, they never achieved a wide-spread usage because of the difficulties and problems in translat ...
Even after decades of software engineering research, complex computer systems still fail, primarily due to nondeterministic bugs that are typically resolved by rebooting. Conceding that Heisenbugs will remain a fact of life, we propose a systematic investi ...
Fault injection is an often overlooked component of the software test cycle, yet it is critical for building robust systems. The main reasons for this neglect are ineffectual tools, an overwhelmingly large number of possible faults to inject, and extensive ...
This paper presents an overview on the IF toolset which is an environment for modelling and validation of heterogeneous real-time systems. The toolset is built upon a rich formalism, the IF notation, allowing structured automata-based system representation ...
