This is last, final, and 10th entry in the ten commandments of unit tests attributes that started here. And you should read all of them. We usually talk about isolation in terms of mocking. Meaning, when we want to write unit tests, and the code has dependencies, we use mocking Read more…
This is the 9th post in the Unit Tests Attribute series that started here. To learn more about testing, contact me. I keep hammering on trust and how it’s crucial that we trust our unit tests. If unit tests are deterministic, they raise the level of our trust. If the Read more…
This the 6th post about Test Attributes that started off with the supermodel of series, “Test attributes – Introduction” post. If you need training on testing, contact me. I always hated the word “maintainability” in the context of tests. Tests, like any other code are maintainable. Unless there comes a Read more…
This the 5th post about Test Attributes that started off with celebrity-level “Test Attributes – Introduction” post. Differentiation is not an attribute of a single test. Differentiation does not ride alone, because it requires multiple tests. Tests allow us to (a) know something is wrong and (b) help us locate Read more…
This is the 4th post on test attributes that were described in the now even more famous “Test Attributes – Introduction” post. If you want training and/or coaching on testing, contact me. Accuracy is about pinpointing the location of the the failing code. If we know where the offending code Read more…
This is the 2nd post on test attributes that were described in the now famous “Test attribute – Introduction” post. We often forget the most of the value we get from tests come after we’ve written them. Sure, TDD helps design the code, but let’s face it, when everything works Read more…
In my last post, I created a list of test attributes. If one of them isn’t ok, you need to do some fixin’. This is the first of a series of posts that is going to discuss the different faces of tests. Let’s start with validity. Admittedly, it’s not the Read more…
When we’re unit testing, we focus on the scenario we want to test, and then write that unit test. Pretty simple, right? That’s how are are minds work. we can’t focus on many things at the same time. TDD acknowledges that and its incremental nature is built around it. TDD Read more…
I’ve been thinking about what makes TDD fail, and there are obviously few reasons that were discussed to death (Get it? Dead? TDD? Ok, let’s move on). There’s a pattern I see when working with beginners. I’m talking about TDD beginners, because these people may have years of experience on Read more…
What make unit tests different than other tests? They are full of FAIL. Going to the Wikipedia definition, you’ll get a vague and unhelpful description, and to summarize: It tests a small piece of code. In what language? What is small? And why does that matter? I feel that many Read more…
