Exploring Extreme Programming
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
Test-Driven Development (TDD) is an approach to designing and implementing software: write tests, write code, refactor, and repeat; all in small steps. I hope you find these TDD resources useful.
As one of Industrial Logic’s consultants, I sometimes make videos, so I thought I’d gather links to those here. Refactoring to Patterns and Other Interesting Places Craft Conf, 2018 (I didn’t make this video, but it’s for a talk I Continue reading Industrial Logic Videos
Some unit tests are focused, other are like a run-on sentence. How can we create tests that are focused and communicate well? Arrange-act-assert is a pattern for good tests. What’s a good structure for a unit test? 3A: Arrange, Act, Continue reading 3A – Arrange, Act, Assert
How does the order of tests affect the design of software? A game to explore that idea. Continue reading Tests from a Hat
