We introduce targeted property-based testing, an enhanced form of property-based testing that aims to make the input generation component of a property-based testing tool guided by a search strategy rather than being completely random. Thus, this testing technique combines the advantages of both search-based and property-based testing. We demonstrate the technique with the framework we have built, called Target, and show its effectiveness on three case studies. The first of them demonstrates how Target can employ simulated annealing to generate sensor network topologies that form configurations with high energy consumption. The second case study shows how the generation of routing trees for a wireless network equipped with directional antennas can be guided to fulfil different energy metrics. The third case study employs Target to test the noninterference property of information-low control abstract machine designs, and compares it with a sophisticated hand-written generator for programs of these abstract machines.

    Kostis Sagonas - A PropEr Tutorial on Property-Based Testing

    240 Mins

    Property-based testing is a novel approach to software testing, where the tester needs only specify the generic structure of valid inputs for the program under test, plus certain properties that the program is expected to satisfy for every valid input. PropEr is an open-source tool for property-based testing in Erlang. One of its salient features is that it provides a tight integration of the language of types and specs of Erlang with property-based testing. Any type can be used as a generator and any function specification can be directly used as a simple property of a function. In addition, PropEr comes with components for testing stateful applications and for targeted property-based testing.

    This hands-on tutorial will introduce through examples the support that PropEr provides for property-based testing in Erlang, present representative examples of its use, and will give advice for the proper use of the tool.

    Aloïs Cochard / Tony Morris - Introduction to Functional Programming using Haskell

    480 Mins

    We will be spending the day learning the fundamentals of Functional Programming (FP) using the Haskell programming language. The exercise material will be a condensed selection of the NICTA/course which is regularly held in Australia over three days.

    This one day session is targeted to experienced industry programmers who are looking to break into Functional Programming and develop the rudimentary skills and techniques that enable continued independent study. A refresher on Haskell syntax will be provided, however, it is highly recommended to practice with the syntax and development tools prior to obtain the best outcome for the day.

    You will be required to bring a suitable development machine (portable) for working through the exercises. You will also need to install Glasgow Haskell Compiler (http://www.haskell.org/ghc/) version 7.8 or higher on that machine prior to the day.

    Git is one of the most popular tool for a developper and a part of the power of Git is come from some functional concepts. So, it's obvious to implement the Git format with OCaml!

    This talk will present the functionnal concepts of Git (like the immutable tree) and show a practical implementation with OCaml step by step. Then, we will explain how can scale an OCaml code to compute a huge Git repository and understand by this way the power of OCaml (and the mix between the functionnal and the imperative way).

    At the end, we will show an example of the usability of Git with OCaml with a concrete application.
