Plainionist Become a Better Developer, Deliver Software Faster

Assumptions aren't that bad in source code if ...

Design-by-Contract is not only an easy way to find bugs earlier, it is also a great tactic to improve your code quality. With Design-by-Contract we can document expectations and assumptions crystal clear in the source code itself and so improve changeability and maintainability!

How this works I explain in this video:

Design-by-Contract for C

Once upon a time a long time ago …

… I worked in a project in the context of embedded systems. The project was developed in C programming language and I wanted to use Design-by-Contract there as well.

The pre-processor worked pretty well for my project and I even contributed to it.

I couldn’t figure out what happened to the source code since RubyForge was shut down but here you can still download the ruby gems:
