Model-Based Testing and Property-Based Testing are two testing methodologies that usually facilitate the automation of the generation of test cases, using either models or properties as basis to derive complete test suites. In doing so, they also contribute to reduce both the source code needed for testing purposes and the time spent on writing those tests,… (More)
In this work, we face the problem of generating good quality test suites and test cases for web services. We present a framework to test web services based on their formal description, following a black-box approach and using Property-Based Testing. Web services are a popular solution to integrate components when building a software system, or to allow… (More)
As an example of the combination of Test Driven Development and Property Based Testing, this paper presents the implementation of a template library from scratch using the functional language Erlang for development and the tool QuickCheck for testing.
In this paper we describe how to infer state machine models of systems from legacy unit test suites, and how to generate new tests from those models. The novelty of our approach is to combine control dependencies and data dependencies in the same model, in contrast to most other work in this area. Combining both kinds of dependency helps us to build more… (More)
Web services are the most widely used service technology that drives the Service-Oriented Computing~(SOC) paradigm. As a result, effective testing of web services is getting increasingly important. In this paper, we present a framework and toolset for testing web services and for evolving test code in sync with the evolution of web services. Our approach to… (More)
Web services are a very popular solution to integrate components when building a software system, or to allow communication between a system and third-party users, providing a flexible, reusable mechanism to access its functionalities. To ensure these properties though, intensive testing of web services is a key activity: we need to verify their behaviour… (More)
