The danger of @InjectMocks

Last week, I wrote about the ways to initialize your Mockito’s mocks and my personal preferences. I’m still working on my legacy project, and I wanted to go deeper into some Mockito’s feature that are used. For example, Mockito’s developers took a real strong opinionated stance on the design: Mockito can only mock public non-final instance methods. That’s something I completely endorse.

Initializing your Mockito mocks

Maintenance projects are not fun compared to greenfield projects, but they sure provide most of the meat for this blog. This week saw me not checking the production code but the tests. What you see in tests reveals much of how the production code itself is written. And it’s a way to change things for the better, with less risks. At first, I only wanted to remove as much PowerMock uses as possible. Then I found out most Mockito spies were not necessary.

Semantics: state or dependency, not both

The more I program, the easier it gets. However, the more questions arise regarding programming. This week, my thinking was about Object-Oriented Programming. I’ve been told that OOP is about encapsulating state and behavior is a single isolated unit. In languages I know, state translates into attributes and behavior into methods. public class Cat { private Color color; public void mew() { ...

Development

Forget the language, the important is the tooling

There’s not one week passing without stumbling upon a post claiming language X is superior to all others, and offers you things you cannot do in other languages, even make your kitchenware shine brightier and sometimes even return lost love. I wouldn’t mind these claims, because some features really open my Java developer mind to the lacking of what I’m using now, but in general, they are just bashing another language - usually Java.

Using a framework or not?

If you haven’t read Uncle Bob latest blog post, you should do now. For impatient readers, it can be summed up with: TL;DR: 'You don’t need frameworks, just write the appropriate code'. It’s not the first time I find myself at odd with Uncle Bob’s writing, which feels awkward in regard to his experience and aura. Another post that drew my attention was about JavaScript.

My case for Event Bus

Informal talks with colleagues around the coffee machine are a great way to improve your developer skills. Most of the time, people don’t agree and that’s a good way to learn about thinking in context. One of the latest subject was about the Event Bus. Though no Android developer, I’m part of a Mobile team that uses an Event Bus to dispatch events among the different components of the application. Amazingly enough, one team member 'doesn’t like Event Bus'.

Going the microservices way - part 3

This is the 3rd post in the Going the microservices way focus series. In the first post of this serie, I created a simple microservice based on a Spring Boot + Data JPA stack to display a list of available products in JSON format. In the second part, I demoed how this app could be uploaded on Pivotal Cloud Foundry. In this post, I’ll demo the required changes to deploy on Heroku.

Going the microservices way - part 2

This is the 2nd post in the Going the microservices way focus series. In my previous post, I developed a simple microservices REST application based on Spring Boot in a few lines of code. Now is the time to put this application in the cloud. In the rest of the article, I suppose you already have an account configured for the provider. Pivotal Cloud Foundry is the Cloud offering from Pivotal, based on Cloud Foundry.

Going the microservices way - part 1

This is the 1st post in the Going the microservices way focus series. <div class='paragraph'> <p><a href='https://en.wikipedia.org/wiki/Microservices' target='_blank' rel='noopener'>Microservices</a>, are trending right now, whether you like it or not. There are good reasons for that as it resolves many issues organizations are faced with.
