This blog is a platform for me to share my knowledge in the area of software development.
In this blog, you will learn how to manage several Java Development Kits (JDKs) on your Linux system using SDKMAN. Besides JDKs, several other SDKs can be managed by means of SDKMAN. Enjoy!

The 14th of September Java 17 was released. Time to take a closer look at the changes since the last LTS release, which is Java 11. A short introduction is given about the licensing model and after that, some of the changes between Java 11 and Java 17 are highlighted, mainly by means of examples. Enjoy!

In our previous post, we showed how to create an AWS Continuous Deployment Pipeline. This post will continue where we left off. We will enhance the pipeline with a Review stage, a more efficient use of the Maven cache and add notifications to the pipeline.

Creating a continuous deployment pipeline will bring us a step closer to an automated build, test, deploy strategy. In order to create such a pipeline, we need to have access to several tools. Instead of installing these on on-premise servers, we can make use of the AWS cloud offer. Let’s see how this can be accomplished!

In this post, we will create a Spring Cloud Function and create some unit tests for it. We will do so by creating a function with Bean definition and with the functional style. At the end, we will deploy the function on AWS Lambda.

In this post, we are going to explore how we can deploy a simple Spring Boot application to AWS Elastic Beanstalk. We will explain how to setup an AWS account and provide a step-by-step guide how to deploy to AWS.

In this post, we will take a look at how we can use Testcontainers for our integration tests. Testcontainers will allow us to write integration tests making use of containerized databases, message queues, web browsers, etc. without a dependency on a local installation.

In this post, we take a look at how we can easily manage our database migration scripts by means of Liquibase. Liquibase will automatically execute necessary database migration scripts during application startup. We will explore some of the features of Liquibase by means of a simple Spring Boot application in combination with a PostgreSQL database.
You have consistently written unit tests and you have a line coverage of, let us say, 80% and all of your tests pass. Pretty good, isn’t it? But then you change your code and still all of your tests pass although you have changed code which is covered by your unit tests. In this post, we will take a look at mutation testing which will test the quality of your unit tests.
Skaffold is a command line tool developed by Google which aims to facilitate continuous development for Kubernetes applications. It will automate the task of building and deploying to a Kubernetes cluster whereas you, as a developer, can stay focused on writing code. Seems interesting enough to take a closer look at it!
