How to implement validation callbacks in AngularJS 1.3

Marc Rooding

In my current project we've recently switched from AngularJS 1.2 to 1.3. Except for a few breaking changes the upgrade was quite trivial. However, after diving into the changelog we noticed that the way AngularJS handles form validation changed drastically. Since we're working on a greenfield application we decided it was worth the effort to rewrite the validation logic. The main argument for this was that the validation we had could be drastically simplified by using the new validation pipeline.

This article is aimed at AngularJS developers interested in the new validation pipeline offered by AngularJS 1.3. Except for a small introduction, this article will not be about all the different aspects related to validating forms. I will showcase 2 different cases in which we had to come up with custom solutions:

  • Displaying additional information after successful validation
  • Validating equality of multiple password fields

CITCON Europe 2014 wrap-up

Arjan Molenaar

On the 19th and 20th of September CITCON (pronounced "kit-con") took place in Zagreb, Croatia. CITCON is dedicated to continuous integration and testing. It brings together some of the most interesting people of the European testing and continuous integration community. These people also determine the topics of the conference.

They can do this because CITCON is an Open Space conference. If you're not familiar with the concept of Open Space, check out Wikipedia. On Friday evening, attendees can pitch their proposals. Through dot voting and (constant) shuffling of the schedule, the attendees create their conference program.

In this post we'll wrap up a few topics that were discussed.

Testing cheatsheet

Jan Toebes

Sometimes it is not clear for everybody how unit tests relates to e2e-test. This cheatsheet, I created, describes in one page:

  1. The different definitions
  2. Different structures of the tests
  3. The importance of unit tests
  4. The importance of e2e tests
  5. External versus internal quality
  6. E2E and unit tests living next to each other

Feel free to download and use it in your project if you feel there is a confusion of tongues between unit and e2e tests.

Ready, Test, Go!

Viktor Clerc

The full potential of many an agile organization is hardly ever reached. Many teams find themselves redefining user stories although they have been committed to as part of the sprint. The ‘ready phase’, meant to get user stories clear and sufficiently detailed so they can be implemented, is missed. How will each user story result in high quality features that deliver business value? The ‘Definition of Ready’ is lacking one important entry: “Automated tests are available.” Ensuring to have testable and hence automated acceptance criteria before committing to user stories in a sprint, allows you to retain focus during the sprint. We define this as: Ready, Test, Go!

The neverending waveform of the full-stack developer

Freek Wielstra

There was an article on Techcrunch a couple days ago which was linked in our internal mailing list the other day, titled The Rise And Fall Of The Full Stack Developer. I read it, and I just couldn't figure out why the title is about "the fall" of the full-stack developer (and I said as much on the mailing list, after which I was encouraged to write this blog post). In this post I'll try and explain why it's not the end, but just a stage in a recurring cycle

Mutation Testing: How Good are your Unit Tests?

Misja Alma

You write unit tests for every piece of code you deliver. Your test coverage is close to 100%. So when the point comes when you have to make some small changes to the existing code, you feel safe and confident that your test suite will protect you against possible mistakes.
You make your changes, and all your tests still pass. You should be fairly confident now that you can commit your new code without breaking anything, right?

Well, maybe not. Maybe your unit tests were fooling you. Sure they covered every line of your code, but they could have performed the wrong assertions.
In this post I will introduce mutation testing. Mutation testing can help you find omissions in your unit tests.

Swift Function Currying

Lammert Westerhoff

One of the lesser known features of Swift is Function Currying. When you read the Swift Language Guide you won't find anything about curried functions. Apple only describes it in their Swift Language Reference. And that's a pity, since it's a very powerful and useful feature that deserves more attention. This post will cover the basics and some scenarios in which it might be useful to use curried functions.

iOS localization tricks for Storyboard and NIB files

Lammert Westerhoff

Localization in iOS from Interface Builder designed UI has never been without any problems. The right way of doing localization is by having multiple Strings files. Duplicating Nib or Storyboard files and then changing the language is not an acceptable method. Luckily Xcode 5 has improved this for Storyboards by introducing Base Localization, but I've personally come across several situations where this didn't work at all or when it seemed buggy. Also Nib (Xib) files without ViewController don't support it.

In this post I'll show a couple of tricks that can help with the Localization of Storyboard and Nib files.

How to Dockerize your Dropwizard Application

Thomas Kruitbosch

If you want to deploy your Dropwizard Application on a Docker server, you can Dockerize your Dropwizard Application. Since a Dropwizard Application is already packaged as an executable Java ARchive file, creating a Docker image for such an application should be easy.


In this blog, you will learn how to Dockerize a Dropwizard Application using 4 easy steps.

How to create Java microservices with Dropwizard

Jan Vermeir

On Tuesday October 14th the Amsterdam Middleware Meetup experimented with Dropwizard. The idea was to find out what this technology is about, where it could be useful and what the alternatives are. So below I’ll give you an overview of Dropwizard and compare it to Spring Boot. Read more
