Testing your Spring Data JPA repository

With Spring Data JPA, persisting data is quite easy. You no longer need to write complex DAO’s or repositories, no, all you need is an interface. If you look at my Spring Boot tutorial, you will see that by writing a few lines of code for creating our interface, we’re able to read, update, delete and […]

Executing Jasmine tests with Maven

A while ago I wrote my very first Spring Boot application and I showed you how fast it could be using Spring Boot and AngularJS. I also thought about testing all sides of the application, so I started with writing some integration tests for my REST API, then I wrote some unit tests using Mockito […]

Unit testing with Mockito and AssertJ

A few weeks ago I wrote my very first Spring Boot application and I was quite astonished about the result. Now, I did want to complete the application by writing some tests and so I did. In my previous tutorial I wrote several integration tests, and now it’s time to write some unit tests as […]

Easy integration testing with Spring Boot and REST-Assured

In my previous article I explained how you could rapidly create a completely working, responsive CRUD application with about 150 lines of code. That’s obviously nice, but Spring Boot also makes it easy to write integration tests for your application, because it’s easy to setup a running test application with a few annotations, so then […]

Rapid prototyping with Spring Boot and AngularJS

Recently I wrote an article about writing modern webapps with Spring Data REST and AngularJS. It’s not that hard to write, but it can be done even easier with Spring Boot as pointed out in the comments by Greg Turnquist. I already planned on trying out Spring Boot after some amazing articles about Spring Boot […]

Building modern webapps using Spring Data REST and AngularJS

Recently I wrote several “exotic” applications using WebSockets. If you’re not into WebSockets, but you’re interested in using Spring and AngularJS, this article may suite you. In this example I will setup a web project using the Spring framework and an in memory embedded HSQL database. The client-side of the application will be written using […]

Writing apps with React.js: Writing components using JSX

In my previous tutorial, I’ve set up gulp.js to build my React.js application, now it’s time to write that application. Like I said before, the app I’m going to build in this tutorial, is an application where you can add/remove songs and rate those. We have several components to implement, so let’s start.

Writing apps with React.js: Build using gulp.js and Browserify

Previous week I went to Devoxx and Pratik Patel gave a great talk about React.js. This was enough for me to start playing with the library. React.js is a JavaScript library for building user interfaces by writing components. It’s a view-oriented library which allows you to write isomorphic components which can be used both in […]

Continuous integration of JavaScript apps using Jenkins

For the past half year I’ve written several articles about JavaScript frameworks and developing pure JavaScript web applications. In this article I will demonstrate how you could use Jenkins, SonarQube and Bower for continuous integration of your JavaScript applications.

How to drink gulp.js

A while back I wrote an article about how to use Grunt to build your application. However, recently there’s a new player on the market called Gulp. I’m not going to compare the two and tell you which one is better, but I’m going to use the same application and try to achieve the same […]
