Product Manager: Man, you still haven’t touched your keyboard? I haven’t seen you doing any Spring or TDD or anything technical yet. Are we going anywhere with this? Me: Of course! It’s calculation time! That’s what you wanted, right? Let’s… Continue Reading…

So many TDD cases, so many posts. And no Spring in sight yet. I promise, we’ll get there. For now, let’s continue to explore the requirements. Where did we last stop? Pressing any digit key, the display adds that digit… Continue Reading…

It is customary to think that in TDD we run ahead and just write tests. Not today, Spring will have to wait. Let’s break down the requirement into test cases, so we can understand them better. Buckle your seat belts,… Continue Reading…

Most TDD examples start out with a calculator. Ours will start here as well. But we’re not going to write a test for “2+2”. No sir, we’re going to test drive the calculator display. But what does it actually do?… Continue Reading…

Now that we’ve covered some of Spring capabilities, we can explore possibilities beyond simple mocking. Instead of “regular” mocks (that we can set up in the integration tests), we can inject actual simulators. For our purpose, let’s define a simulator… Continue Reading…

Last time, in the first post in my new clean code series, we discussed how I torment my students with the ol’ Square and Rectangle trick in my Clean Code course, talking about Liskov Substitution Principle (LSP). At the end… Continue Reading…

In my Clean Code class, I go through this example about the Liskov Substitution Principle (LSP), part of the SOLID material. This example, the rectangle and the square, never fails to stump people, both experienced and less so. It starts out… Continue Reading…
