Ok, time to run the test. Well, that’s interesting. The test is not even running until the end, we’re crashing before it completes. Let’s see what’s wrong. Seems that this line breaks: List<Ingredient> fillingIngredients = new ArrayList<Ingredient>(ingredients.subList(1, ingredients.size() – 1));… Continue Reading…

Last time we talked about flow analysis in the code. We figured out the cases we want covered. But, even for these cases, we don’t know what the expected result is. It’s worse than that in the real world. In our… Continue Reading…

The current code version we’re talking about is tag 1.1. Last time, we have surrounded our code with a boundary, doing some early refactoring. We now know the entry points, and the exits are covered by interfaces, leaving code we… Continue Reading…

Check out the original version of the code (Java, and also in C#, in tag 1.0). Right, time to move some code around. Before we do that, remember step #1 in our process: Draw a line around our tested code.… Continue Reading…

Other awesome posts in the series: So we talked about static constructors and how to go around them. How about instance constructors? Are they innocent or guilty of the same crimes as their static brothers? I think Java got the… Continue Reading…

The other posts in the series: Where we last left off, we discussed how to dismantle the static constructor (or initializer) booby traps. And I promised you an example. I’ll do that in C#, but the operations apply to any… Continue Reading…

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… Continue Reading…
