Title: Your tests as a simulator 6.30- 7.00

Abstract: Test Driven Development advocates to write a test before you write your code. It ensures that you have some test cases in place and that your final implementation is indeed reasonably tested. However, for quick prototyping, one still has the feeling to do duplicated work. In this talk we show how for deterministic C or Erlang programs, one can use the test cases for simulation. That is: it suffices to write the test code, writing the actual code is no longer needed.
The talk is based upon work in progress in the context of the Prowess project, an EU funded research project for testing web services.

Title: Writing bindings between Erlang property testing and Javascript because I had one bugfix to make 7.15- 8.00

Abstract: When writing a Go (board game) client and server there was an algorithm on the Javascript side that I needed to write that
manipulated variations in the board state, this proved to be
non-trivial, and something that required testing to get right. After
shrugging off the idea of writing a single case unit-test, I decided
to instead spend the next 2 days adapting Erlang QuickChecking to work with Javascript using Basho's erlang_js project. The bug is now fixed.
