I was honored to come back to JCON, and present “How to TDD in Legacy Code”. In Java of course. Ok, it was in English, the examples were in Java. TDD (Test driven development) is not just new code, you know. Anyway, watch it here. And if you’re itching for Read more…
I know, I know, you probably thought it couldn’t be done in Python. Wrong!! In this session, presented at Python Web Conference 2022, I present the TDD a REST API session, in Python, using Flask as a web container. So no more excuses. Pythonistas! Go TDD your services. Just after Read more…
Well that’s a new thing! Sort of new. Well, the session is not new. Everybody now does TDD in legacy code. But in Python? Gil, are you saying that you can do these things in Python? Shocked, I tell you. Well, not really, TDD principles are universal, They can be Read more…
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…
