Most Spring Boot projects treat src/test/java as an internal implementation detail: it exists to make CI green and never leaves the build machine. But there’s a useful pattern that turns a subset of your tests into a portable, deployable artifact — one you can run after a deployment, against a…

In the previous post, i explained adapter, service and facade in the context of rest api. hier further design patterns in the spring boot/ Java context. Six patterns, one REST-backed domain (City weather lookup), minimal code, minimal words. 1. Adapter Translates an external contract into your domain model. java 2.…

Adapter — wraps the external API, translates its shape into your domain shape. java Service — contains business logic, uses the adapter, doesn’t know about HTTP. java Facade — combines multiple services/adapters behind one simple entry point. java In one line:

Manchmal fehlt uns nicht das Wissen. Manchmal fehlen uns nicht die Fähigkeiten. Und oft fehlt uns auch nicht die Erfahrung. Was uns fehlt, ist der Mut, uns selbst etwas zuzutrauen. Ich kenne das von mir selbst. Es gibt Situationen, in denen ich genau weiß, dass ich die nötigen Kenntnisse habe.…

Black Box Testing What it is: Testing the application without knowledge of its internal code or structure. The tester only sees inputs and outputs. Focus: Functionality, not implementation. Key points: Use it when: White Box Testing What it is: Testing with full knowledge of the internal code, logic, and structure.…

Continue reading →: Testing HTTP Clients in Java with WireMock and Spring Boot
When a Spring Boot application calls an external REST API, integration tests face a familiar problem: the real service might be slow, unavailable, or simply impossible to control. WireMock solves this by running a local HTTP server that simulates the external API. You define stubs — rules that say „if…
