This is a quick write-up on how to get started with graphite as a .Net developer. We’re going to start using graphite with a virtual machine in VirtualBox, although you could use something else also. Steps: Download/install VirtualBox Download/install Ubuntu Download/install Graphite Expose VM to network Use Graphite from C# Download/install VirtualBox Start by downloading [...]

The Facebook Test Java API framework has been updated. There are two additions to the API and one bugfix: Bugfix for NPE when calling facebookStore.createTestUser(false,”…”). Added possibility of using a provided HttpClient instance in HttpClientFacebookTestUserStore. Added unit test that displays the use of json-path when asserting data. Here’s a quick reminder of how to create [...]

I previously wrote a blog post titled Performing any Selector on the Main Thread detailing a convenience category on NSInvoication for easily creating invocation objects that could be invoked on any thread. This category has served me well, and even got traction in the iOS developer community, so I never bothered to stop and think [...]

There is a vibrant community of open source projects for iOS. You need a calendar UI components or a JSON parser? No problem, the projects are out there. Most code out there is of very high quality. Unfortunately the distribution of the code is generally very crude, barely half a step away from sharing code [...]

Since november 2010 you may create test user accounts on Facebook for your application, so that you may test your application without creating dummy accounts and possibly break the Facebook EULA. The test users may be managed using the Facebook Graph API. The application I was working on, which integrated with Facebook, needed automated integration [...]

Introduction Testing asynchronous systems is hard. Not only does it require handling threads, timeouts and concurrency issues, but the intent of the test code can be obscured by all these details. Awaility is a DSL that allows you to express expectations of a asynchronous system in a concise and easy to read manner. Simple example [...]

Many UI frameworks, including AppKit for Mac OS X and UIKit for iPhone OS, require that all methods to UI components are sent on the main UI thread. Cocoa and Cocoa Touch make this quite easy by providing for example -[NSObject performSelectorOnMainThread:withObject:waitUntilDone:] in Foundation. Making updating the text for a text field a snap: [someTextField [...]

I’m going to guess that most of you know what instrumentation is. In the event that you don’t, instrumentation is a feature in which specific monitoring of the interactions between an application and the system is made possible. Instrumentation also makes it possible to write test cases that interact with the application. The problem with [...]

Problem When working on www.beertoplist.com I ran into a Maven problem, that is fairly common: Having a project that should be configured differently for different environments. That is for instance you want one configuration for development, one for test and one for production. I wanted a solution that allowed me to make changes to all [...]

Background In PowerMock we’re using a custom classloader to byte-code manipulate classes that are normally not mockable to make them mockable. But when running a test case there may be some cases when the user needs to byte-code manipulate a certain class (X) in the first test method but needs to have the class unmodified [...]

After having it on our todo list for at least a year we’ve finally managed to integrate PowerMock with TestNG 5.11 as of PowerMock version 1.3.5. This is a big milestone of the project since we’ve now demonstrated that PowerMock is decoupled from both a specific test framework and a specific mock framework. The TestNG [...]

The directory servers of today are packed with a lot of nice features, one of them being Referential Integrity which performs integrity updates on attributes like member, uniqueMember, owner etc. Simpler put, when an entry updates its distinguished name, all references using the old distinguished name get updated to the new one. However, there can [...]

Today I was trying to setup the Android SDK (version 1.6_r1) on the 64 bit version of Ubuntu 9.04 (Jaunty Jackalope). After having installed the ADT Eclipse plugin and pointed out the Android SDK directory in the settings I immediately ran into the following error: Failed to get the adb version: Cannot run program “/home/johan/devtools/android/android-sdk-linux_x86-1.6_r1/tools/adb”: [...]

As Halloween is approaching and the aftternoons grow rainy, it’s time for some tinkering. So, why not try to get the pumpkins a bit more interesting than cut-out veggies? Getting some tinkerers together was no problem, so we got three families with kids, 4 pumpkins, one LEGO Mindstorms set and 2 Arduinos to start with. [...]

This is a long article to follow up my talk at SSWC, so I will start with a summary for the lazy reader Summary With connected devices, JavaScript enabled web sites and the extensibility of the XMPP protocol, we are at the beginning of a new kind of applications that are operating in the social [...]
