Minimal Spring Security Context Setup for Unit Testing

Leider ist der Eintrag nur auf Britisches Englisch 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 ... Read more

SCuri: Automating Unit Test Boilerplate Code for Angular Components

Leider ist der Eintrag nur auf Britisches Englisch 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 ... Read more

Revisiting Popular Posts: Spring Batch Resources & Maven Failsafe With Spring Boot

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.Two of the most popular posts on this blog cover resources for Spring Batch and how to use Maven Failsafe with Spring Boot: Spring Batch Resources: Batch Processing, ETL And Data Conversion Using Maven Failsafe With Spring Boot While doing some regular blog housekeeping, I recently revised those articles and fixed a few broken links. If you're interested in these technologies and frameworks, you might want to check those articles out. Read more

Using Maven Failsafe With Spring Boot

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.Maven Failsafe is a Maven plugin designed to be used in conjunction with the Maven Surefire Plugin. While the former plugin is intended for running integration tests the latter's purpose is to run unit tests. These plugins are tremendously useful for partitioning tests in Maven-based Java applications in order to make tests and builds run faster. When recently using Maven Failsafe with a Spring Boot application, though, I encountered a somewhat gnarly problem. Running mvn ... Read more

Mock Data Generators for Tabular Data

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.Developing a JavaScript-based web front-end, e.g. with frameworks such as Angular, at some point - especially during the prototype phase - often requires working with data supplied by a back-end data source. Tools such as JSON Server enable you to spin up such a data source as a REST API server in no time with zero coding involved. However, running a back-end server is only part of the equation that is testing a front-end against ... Read more

Dependency Management for Angular Unit Tests Using TestModuleMetadata

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.Since its inception it's always been one of the eminent design goals of Angular (and AngularJS before it) to make JavaScript applications easily testable and bake unit and E2E testing right into the development process. While the Angular team certainly has succeeded at this there's still the occasional snag you hit when writing unit or end-to-end tests. For the most part, the testing experience with Angular is terrific and testing JavaScript codebases has come ... Read more

Testing REST Services with REST Assured

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.RESTful service testing can be unwieldy and difficult to get started with. Providing a REST API implies using a variety of technologies and techniques such as HTTP, JSON, authentication, various payload transfer mechanisms and content types. This is where a tool that abstracts over these technical details and facilitates their application comes in handy. REST Assured is a high-level DSL for testing REST APIs. It draws upon behaviour-driven development (BDD) and hence makes ... Read more
