In this presentation I will show all the tools I use to write software that does not break but keeps the users happy. Static types, exception monitoring, unit tests with snapshots, randomized testing, code and data coverage, code complexity metrics and awesome end to end testing tools - the list is long and keeps on growing! The techniques I plan to show are applicable to every framework and environment.
