We’ve come up with a few alternatives for the APIs (their draft version, anyway). I’m going to weigh them here, and remind ourselves – this is the internal API forma, but also has a REST counterpart. Let’s talk about each of the options, but this time, not just about how Read more…
Last time, we started thinking about considerations for picking the right test to start with. We decided to start with integration tests. So, which cases do we want to cover? Obviously, they should capture the main functionality of the system. Going over our test cases, the following are the main Read more…
When we set up the project, we ran a couple of tests (integration and unit) to see if the environment we have runs them. There was no actual logic involved, but we got initial feedback that the platform is ready to work as-is. The next logical step is to set Read more…
Finally! Actual TDD and code and Spring! Well, we’ll start with Spring first. But first a reminder. We’ve already constrained ourselves with the architecture. This is going to be a web based, REST services based Spring application. In the general case, the architecture should support building the app in the Read more…
PM: You know, you could have something built by now. You do call this series “integration testing with Spring TDD” or something. Me: Yeah, and I would probably build something you did not want. Just a few more cases. Remember, we were talking about actual calculations and special cases? PM: Read more…
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 write some examples. Pressing “=” shows the calculation result. There Read more…
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 to the existing display. The exception is ‘0’ which is Read more…
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, it’s going to be a bumpy ride. We’ll translate the Read more…
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? We’re going to create a simple calculator as a web Read more…
I’ve been working with teams who use Spring as the basis of their programming for some time now. Spring, many times as a microservices development and runtime framework. Luckily (or not) they want to incorporate TDD (Test driven development) into their development, but they bump into all kinds of problems. Read more…
