You probably already heard of Kubernetes, a powerful orchestrator that will ease deployment and automatically manage your applications on a set of machines, called a Cluster.
With great power comes great complexity, even in the eyes of Google. Thus, learning Kubernetes is oftentimes considered as cumbersome and complex, namely because of the number of new concepts you have to learn. On the other hand, those very same concepts can be found in other orchestrators. As a result, mastering them will ease your onboarding on other orchestrators, such as Docker Swarm.
The aim of this article is to explain the most…
Spring Boot is a web framework built on top of the framework Spring. It is designed for easier use and quicker implementation. It does so by configuring the application and its environment as automatically as possible. As a newcomer, I can say that it makes the framework really easy to get into.
My learning led me to read most of the reference documentation, which is well written and gives you a lot of insights into the internal behavior of Spring Boot. This documentation gives a lot of details, so this article aims to take the counter approach and pinpoint the…
Tests are an essential part of software development as they give a ground truth about the code sanity. As developers, we reasonably expect our unit tests to give the same results if the source code does not change. It can happen, however, that the result of a unit test changes over multiple executions of a test suite without any change in the code. Such a test is named a flaky test.
A flaky test is not dangerous per se but reduces the confidence a developer can give to his test suite, diminishing the benefits of the latter. …
What is dependency injection?
Dependency injection (DI) is a very simple concept that aims to decouple components of your software and ease their integration and testing. It does so by asking for their sub-components instead of creating them.
During this article, we will also mention inversion of control (IoC), which is commonly used along with dependency injection. This pattern aims to avoid asking for implementations but rather interfaces while injecting dependencies.
This article will use a simple example in Java to present dependency injection but aims towards a technology-agnostic explanation of the concept and its advantages. …
