Title says it all. Well, I’ll add that this was take #20 (or so). It’s rough getting back in to video recording mode. I will do more in this series.

And I barely know Objective-C, so as the series progresses, I’ll expect some help on better practices.

First Pass Completed: Rough Draft TDD Demonstration Videos 131

Posted by Brett Schuchert Mon, 05 Apr 2010 06:15:00 GMT

As promised, I’ve made a complete sweep through a series of videos. You can find all of them: here.

These videos include several warts and false starts. Depending on the interest and feedback, I’ll redo these at some point in the future.

Question: Should I repeat this series in C#, or some other language? Some people have expressed interest in this. It’s probably 15 hours of work in C#, so I’d need to know it was worth the effort. What’s your opinion on that?

The videos are meant to be watched in order. The link above is to an album that is in the correct order. Here are the direct links (also in the intended order):
  • Getting Started
  • Adding Basic Operators
  • Removing Duplication
  • Extracting to Strategy
  • Removing Duplication via Refactoring or Removing Duplication via Tdd using Mockito
  • Introducing an Abstract Factory
  • Adding a Sum operator
  • Adding Prime Factors Operator
  • Composing Operators and Programming the Calculator
  • Using FitNesse to Program the Calculator

I’ve already received several comments both here on the blog as well as with the videos. I’ll keep track of those comments and incorporate the ones that fit for me.

Each video has a link on its page to download it. However, to download a video, you will have to create an account and log in. So here are the links, these won’t work without first creating an account (I’ll update original blog with these as well):
  • Getting Started Download
  • Adding Basic Ops Download
  • Removing Duplication Download
  • Extracting to Strategy
  • Removing Dups/Refactoring Download
  • Removing Dups/Tdd Download
  • Abstract Factory Download
  • Sum Operator Download
  • Prime Factors Download
  • Composing Math Operators Download
  • Using FitNesse Download

Some Rough Draft TDD Demonstration Videos 203

Posted by Brett Schuchert Wed, 31 Mar 2010 02:01:00 GMT

I’m doing a series of videos on TDD. The ultimate result will be a much more polished version with embedded slides, and such. But as a part of the development process, I’m creating scratch videos.

Much of what you see in these videos will be in the final versions, but those are far in the future relative to this work.

Hope you find them interesting.

Comments welcome.

Here is what is already available:
  • Getting started
  • Adding Operators
Next up:
  • Removing violation of Open/Closed principle
  • Removing duplication in operations with a combination of the Strategy pattern and the Template Method pattern
  • Adding new operators after the removal of duplication.
  • Reducing coupling by using the Abstract Factory pattern, Dependency Inversion and Dependency Injection
  • Adding a few more operations
  • Allowing the creation of complex “programs” or “macros” by using the Composite pattern – and avoiding Liskov Substitution Principle inherent in the GoF version of the pattern
  • Driving the calculator via FitNesse + Slim

Anyway, that’s the plan. I’ll try to add each of these videos over the next few weeks.
