Exploring Extreme Programming
The vocabulary of your user stories frames the domain of discourse: what are your stories about? It’s helpful to think of “the headline” and “the rest”. “The headline” is what you’d write on an index card or as a title Continue reading User Story Vocabulary: Problem, Solution, or Widget?
How do you handle delivery of new features or new systems? The easiest way is to just add the new features or replace the existing system, with no transition, but this is not the only approach. We’ll consider several strategies Continue reading Delivery Strategies
We’ll look at two refactorings suitable for conditional statements: Pull Up Common Head of Conditional and Pull Down Common Tail of Conditional. I originally learned these as performance optimizations but they also help simplify and clarify code. In Refactoring, Martin Continue reading Refactoring: Pull Common Code from Conditional
Rather than focusing on “splitting” a story, figure out a minimal form of a story, and intensify it – make it more powerful or desirable. We’ll explore one dimension, prediction: how can we make a story better by improving how the Continue reading Intensifying Stories Through Prediction
We implement feature by feature, seeking value; adding up the value forms an S curve with characteristic regions. Can we overcome the tendency of products to fade away?
TDD – Test-Driven Development – is one of the tools people use to improve their programming. Many teams find that this discipline helps them reduce their defects. Could it make a difference to your team? Explore with this calculator.
In our final article in the series on testing graphics, we’ll look at testing internal objects (rather than testing at the display level). We’ll look at several decisions around testing.
Screen-Based Tests: Two Extremes Screen-based tests focus on what’s visible rather than internal representations. We’ll consider two extremes for testing screen-based output: fully manual and fully automated. Then we’ll look at moves that can help you evolve from one to Continue reading Screen-Based Tests: Testing Graphics, Part 3
In Part 1, we discussed models for graphics. As we move into testing, let’s start with the visible part: the display.
Many applications work with graphics; applications with graphical user interfaces can’t escape them. We’ll look at several models for graphics, and in later articles explore how to test them.
