Testing in Spring Boot applications

In addition to production code, we typically also write tests to discover and correct possible errors as early as possible in the development process. For new functionality, it isn’t even uncommon to write more test code than production code. At the same time, the tests should be as fast as possible, so they can be executed frequently without causing long delays. In this article, we explore how this can be done in applications based on Spring Boot.

Is Platform Engineering the new DevOps?

When companies transition to the cloud, they anticipate an improved developer workflow, shorter release cycles, and more robust end-to-end team responsibility. However, even after the admin team delivers the new platform with all its capabilities, software teams may hesitate to adopt it and assume responsibility. But why? Is it not every developer’s desire to control the process from committing code to deploying it to production? One possible explanation is a lack of emphasis on the developer experience during platform conceptualization. This article aims to identify common issues and explore whether platform engineering can help to address them.

Safety, Energieeffizienz und User Experience

Bei der Softwarearchitektur gilt es, ein Fundament für robuste und qualitativ hochwertige Softwaresysteme zu entwerfen. Softwarequalität beschränkt sich dabei nicht auf Attribute, die bereits während der Softwareentwicklung gewährleistet werden können. Ihnen zur Seite steht ein Block von Qualitätsmerkmalen, deren Ausprägung sich erst während der Softwarenutzung offenbart. Dieser Blogbeitrag beleuchtet diesen Block und dessen Zusammenhang mit Safety, Energieeffizienz und User Experience (UX).

How we cut our website’s carbon emissions in half

Between 2010 and 2030, the environmental impact of the digital world is expected to triple. While network infrastructure and devices get more and more efficient, all of these improvements are eaten up by more and more people and devices being connected to the internet, but especially by websites which are becoming more and more bloated. On the desktop, the average page weight of a single web page is four times as much now as it was in 2010. On mobile devices, it’s even more dramatic: The average page weight is ten times as much as in 2010. In the summer of 2022, we decided that it’s about time that we take action and start decarbonising our company website.

Was ist ein Data Contract?

Ein Data Contract definiert die Struktur, das Format, die Semantik, die Qualität und die Nutzungsbedingungen für den Datenaustausch zwischen einem Datenanbieter und seinen Konsumenten. Es ist damit ein zentrales Werkzeug, damit sich Teams über Daten-Schnittstellen verständigen können und somit Stabilität, Datenqualität und Nachvollziehbarkeit in der Datenarchitektur gewährleisten.
