Here is the rest of the gang: This time we’re going to tackle the most problematic issue in testing object-oriented languages. Obviously because constructors only exist in those, but also, because even power tools have problems handling them. But we’ll start Read more…
Each stage of implementation is hard in its own way. When we start out with a new effort or process, we think of it as: Sure, it will be hard in the beginning, but it’s going to become easier as Read more…
Kevlin Henney asked once: Why do cars have brakes? Imagine if cars didn’t have brakes, how fast would you go? You’ll be driving really slow to not hit anything. But by giving the capability to slow down, brakes actually give Read more…
TDD is pretty simple right? Obey the red-green-refactor step-by-step and you’re on your way to glorious, non-legacy code. It’s really easy to explain. The rules are easy to follow. Why then so few people actually do it, and when they Read more…
Introducing TDD is a lot more psychological than you think. When we start introducing TDD we need to think about how people new will react. For example, the first question that people ask is: How am I going to write Read more…
I know, you want to check out the rest of the series. Here are the links: Code simplification is one of the best things we can do for ourselves. If we understand the code, not only will we write simpler Read more…
You didn’t think we’ve covered everything, did you? Here’s a short reminder of what we got through: Today we’re going to talk about the Introduce Parameter refactoring pattern. This is one of the more useful patterns to clear code from dependencies. Here’s Read more…
If the 2nd D in TDD is design, then we’re talking about emergent design. The tests drive the design, which emerges from thin air, and step by step reveals itself in all its glory. Emergent design has got to be Read more…
This is the 5th and final part of the series about analyzing what we’re coding, and therefore what to test. Last time, we actually got to writing the tests. Let’s do some cleanup. Step 8: Review Once we have the Read more…
This is the 4th part of the series about analyzing our code and deciding what to test. Last time, we talked about design constraints. Now we’re moving towards the code itself. Almost there. Step 6: Prepare existing code This is an obvious step Read more…
