ArchUnit Spring Integration

Leider ist der Eintrag nur auf English verfügbar.ArchUnit is a tremendously useful library for enforcing Java application architecture via unit testing. Fellow software developer and consultant Roland Weisleder recently published a new library called ArchUnit Spring Integration that helps with - well - better integrating ArchUnit with Spring applications. By introducing a DSL, ArchUnit Spring Integration allows you to easily enforce constraints regarding common Spring stereotypes such as @RestController. For example, using ArchUnit Spring Integration you can make sure that methods annotated with ...

WireMock Spring Boot

Leider ist der Eintrag nur auf English verfügbar.WireMock is an API mocking tool that enables developers to simulate REST APIs during testing.

Clearing the Spring Security Context During Unit Testing

Leider ist der Eintrag nur auf English verfügbar.Last week I wrote about a minimal Spring Security Context setup for unit testing. I'd like to add just a tiny, yet depending on your use case perhaps quite important, tidbit to that: In case you need to reset a SecurityContext setup, e.g., a mocked user authentication, because, for instance, other test methods from the same unit test class verify behaviour for an unauthenticated application state and hence expect an anonymous user, you can ...

Minimal Spring Security Context Setup for Unit Testing

Leider ist der Eintrag nur auf English verfügbar.Creating a minimal Spring Security setup for JUnit unit tests can be a tedious as well as somewhat daunting task. With its Authentication, Principal, GrantedAuthority, and UserDetails classes Spring Security is extremely flexible and configurable and probably accommodates pretty much every authentication and authorization use case under the sun. However, in software architecture such flexibility often comes at price, the trade-off in this case being that simple use cases can require more implementation effort than ...

SCuri: Automating Unit Test Boilerplate Code for Angular Components

Leider ist der Eintrag nur auf English verfügbar.As I wrote about quite some time ago in this blog post, which details my solution for managing transitive dependencies for Angular unit tests . although Angular applications in general are easily testable and unit tests are first-class citizens with the framework itself, there's still some potential for improvement when in it comes to test maintainability. In particular, listing and referencing an Angular component's dependencies (i.e. the dependencies of the system under test) such as ...
