Testability

I have been working with Node.js for almost 6 years now (started back in 2012 with 0.6.10). During these years, co-workers have been asking me the same question over and over again: "What does your application look like?". It is now time to answer this question (or at least try to) !

In most iOS apps, as app developers, we pay a very special attention to the user interface. For example, we try to perfectly implement the graphical design as proposed by the designer. But on the other hand, we pay very little attention to the other parts of the app such as the the data management or the network layer. In this article, I will explain why, during my last project, as we were trying to improve the unit tests of our network calls, we decided…

span.code { font-family: monospace; font-size: 1.2em; } This article is about testing private methods in android. This is a fairly common problem in android (even in Java at large) and can be solved easily. The technique proposed here provides the additionnal benefit of using a traditional way of solving the problem in the Java world. (suspense :) ) Using the android platform, you are used to divide your application into two projects : one for the main source code of your application, one for the tests

There is one major flaw you must have encountered whilst working with Silverlight for a while: its incompatibility with unit tests! Unless you’ve been using Silverlight solely for drawing circles and rectangles, surely you must have tried to use the Silverlight Toolkit unit test project template to try to put some TDD in your project ! ...most probably you were disappointed by it because it’s fairly poor...

MVVM is a quite mature design pattern one can use with the microsoft WPF framework, or with Silverlight. You'll find a lot of literature and tools on the web to start a new development with this pattern. In this article, we show how MVVM can be implemented for a quite large application, and the value it brings in a Behavior Driven Development approach.

With the Flex framework, we are able to quickly develop a GUI that works, especially through the MXML language. Indeed, this language is an effective way to describe the interface with a few lines of code. The problem occurs after the POC step is done, MXML code complexity increases, ActionScript code which implements event handlers, services calls or business logic creeps slowly into the MXML code. After some time, it becomes harder to figure out where data being displayed come from (ie. which code updated…
