  This presentation will show how to transform a Ruby application without tests into a well-spec'd (via rspec) system with good test coverage. The presentation teaches how to write "characterization tests" for Ruby systems, how to convert characterization tests into normal specifications, and how to refactor and add new functionality to the improved system. The code to be tested ...

We've all got phones and applications we care about. Combine the two: let home-grown and open-source apps answer the phone, place calls, and control calls: voice recordings, ad-hoc conferences, menus, prompts, dynamic text-to-speech -- all tailored to the app, the problem, and the way you want it to work. Troy will dig into Ruby APIs for interacting with phone calls at different levels of compl...

This benefits developers by allowing them to find their own errors sooner saving time and resources. Bio Rustan Leino and Mike Barnett are part of an academic research time within Microsoft Res...

This presentation will cover some cases where the imperative paradigm fails and introduce Ruleby - a tool that adds a declarative nature to existing programs. Ruleby is an open source rule engine written in the Ruby language. It is a system for executing a set of if-then statements known as production rules. These rules are matched to objects using a specially designed algorithm that improves p...

Sit in like a fly on the wall with a development team as they wrestle with the issues of testing and the use of mock objects. Three acts cover using mock objects to remove dependencies on external dependencies, explore the use of mocks to isolate the code under test from the rest of the system, and look at when mocking can be an indication of a poor design. This is not your standard presentatio...
