Exploring Extreme Programming
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.
Oracles are things that can tell us whether or not a result is correct. For some tests, an oracle is as simple as comparing a couple strings or numbers. Other tests have many acceptable results and it’s harder to know what’s right. I Continue reading Testing with Simple and Combinatorial Oracles
I’m calling this “Resources on Agile Testing” but I’m not drawing a very sharp line about what’s Agile Testing vs. Good Testing. Further suggestions are welcome!

T is for Testable in the INVEST model. A testable story is one for which, given any inputs, we can agree on the expected system behavior and/or outputs.
French translationS is for Small in the INVEST acronym. I now use another S that I think captures the idea even better: Scalable. Scalable means “able to be changed in size or scale,” and that’s handy in a story: We Continue reading Small – Scalable – Stories in the INVEST Model
