Beyond Error Handling - Using Design To Prevent Errors (Michael Feathers)
Limited Capacity seats available

It would be easy to say that error handling is a black art in software development but that implies that there is some secret stash of knowledge out there. The truth is that we tend to think of error handling as a "lesser concern." If we know how to throw and catch exceptions, we feel that we are okay.
The fact of the matter is - we aren't okay. Error handling in applications is often a symptom of incomplete design. This workshop will focus on techniques you can use to systematically increase the robustness of code by rooting out potential errors and designing them away.
Attendees should bring laptops with a Java development environment. Attendees should also have reading-level understanding of Ruby code.
Learning Outcomes:
  • Learn a Model for Software Robustness
  • Understand Trusted Cores and Type Tunneling
  • Understand the connection between "Tell, Don't Ask" and Error Propagation
  • Learn Techniques for Reducing Variation at Software Interfaces
  • Acquire Guidance for Exceptions, Null Objects, and Option Types
