Book Review: Growing Object-Oriented software guided by tests

Finally I finished reading Growing Object-Oriented software guided by tests [http://www.amazon.com/Growing-Object-Oriented-Software-Guided-Tests/dp/0321503627] , by Steve Freeman and Nat Pryce. We ran it as a reading circle at RemoteX [http://www.remotex.se] but I think I’m the only one that will finish it, and I

Continuous delivery implementations differ due to company testing culture

I just finished reading a post [http://prettyprint.me/2011/01/24/continuous-deployment-at-outbrain/] about continuous delivery [http://continuousdelivery.com/] at Outbrain [http://www.outbrain.com/]. It’s quite interesting they made a trip similar to what we have done at RemoteX [http://www.remotex.se]. However their setup is some

Hudson

PowerShell logs even caught errors

An interesting PowerShell feature is that all errors are collected in an array called $error. so for example if you throw an error you can echo $error and find it later: [https://www.morkeleb.com/img/f41420fe702a_A9B8/image.png] However the error is also logged even if you catch

RemoteX

The PropertyChangedCallback on a DependecyProperty is never called on NotifyPropertyChangedEvents for certain properties

The user interface of RemoteX [http://www.remotex.se] Applications has a concept of linking objects to each other. This is described in the UI very similar to a link on a webpage. Some of these links can be changed using an autocomplete like scenario. These links have had us

JavaScript

Basic Authorization fails for special characters with JQuery on mobile-web-kit

We are using Basic Authorization for our REST-api at RemoteX [http://www.remotex.se] and it’s no surprise that we have a lot of special characters in our usernames (åäö and spaces). What’s interesting is that using JQuery.ajax() with just username and password will fail for these

Design

Making it easy to work with performance

We’ve been working with performance in our REST API a while back. We’ve been considering different options for measuring our API in production, but we had an idea to use the design of the API itself to handle the measuring. Part of the inspiration came from the Changlelog

JavaScript

The power of nested describes in Jasmine

I’m experimenting with the Jasmine JavaScript testing framework to see if I can create a cucumber style testing framework using JavaScript. I want to go full out TDD on it so I started with a feature file, now I’m working on a spec to get that file running.

Hudson

Job dependencies in Hudson for our Continuous Delivery effort

I’m continuing our work with our Continuous Delivery effort. Were migrating from our previous build system to Hudson since it makes builds much more accessible. The work started with the continuous delivery with hudson [https://github.com/morkeleb/continuous-delivery-with-hudson] project I have on github and were slowly adapting a

Development as a team or development as stars?

A good friend and colleague of mine Johan Andersson [http://johan.andersson.net/] read somewhere that you can see the communication patterns of a company in the architecture. I can see how that makes sense, but I think its much clearer than that. I think you can see the communication

What if I worked with a story to being with?

I’ve been working on a pet project, just to see if my idea was possible at all. Central to the idea was sharing of content between users, and I wanted to see if I could build a model to make it work on Google AppEngine. Now I started out

Testing

Running tests as files change

I mentioned earlier a solution [https://www.morkeleb.com/2010/04/14/running-django-tests-automatically-on-save-in-eclipse/] where Eclipse would run all my Python tests when I save a file. This is very convenient when using TDD in languages that can run tests fast. However that solution is tied to Eclipse and as I

JavaScript

Adding elements to mustache.js templates

I’ve been experimenting with Mustache.js [https://github.com/janl/mustache.js/] to do templating for a JavaScript project of mine. One thing that I’m having trouble with is that there’s no way to add more dynamic elements to the resulting template. The output is an HTML

Book Review: JavaScript the Good parts

Markus Andersson [http://twitter.com/#!/markus_marib] recently recommended a book to me called JavaScript the Good parts, by Douglas Crockford. As we were discussing inheritance around JavaScript it came up, so to demonstrate to power of my Kindle I purchased it so we could check out the specific example

Tools

Introducing Tool tax

[https://www.morkeleb.com/img/IntroducingTooltax_968D/taxattorneylosangeles1.gif] I’ve been trying out a few different “tools” just too see what tooling looks like in different environments. There are several different tools solving the same problem in their own more or less unique way. They also take different amounts

Working with Jasmine

I’ve been working extensively with JavaScript these past weeks. As I mentioned earlier I wanted to try out Jasmine [http://pivotal.github.com/jasmine/] and I definitively got the chance. I’ve been using it for all my testing needs these last weeks, and I love it. What do

CI

Making Hudson (Jenkins) update it self

A funny thing happens when you start delivering software through an automated system. You need to find a way to upgrade the automated system, and yet it is in use all of a sudden. Luckily for us we have everything checked into Git [https://www.morkeleb.com/2011/01/17/

Testing

Unit-testing writing styles in QUnit (JavaScript) vs xUnit/MSTest

Every now and then there are people doing experiments with different ways to name tests. The first time I was inspired to adopt a new way to name my tests was after Corey Haines performance kata [http://blog.envylabs.com/2009/08/corey-haines-performance-kata/] (no I wasn’t there I saw

MSBuild projects prebuild step can fail when building with Hudson

I’ve recently ran into a problem where Hudson wouldn’t compile our solution since it will fail when were doing some special work in a prebuild step. The reason was that we had some project with a prebuild step that used the “find” command line tool. However if you

Git plugin for Hudson hangs when fetching

I had issues with getting Git up and running in a Hudson that was hosted as a Windows Service. The Git Commands would simply hang, the console output stopped at the line where the Git command was executed. If I took the service down and started hudson from the command-line

Disabling PlatformVerificationTask for CompactFramework projects

So I’ve been working a lot with setting up Hudson to build our applications. I ran into some issues that I’d like to share. When running on Hudson Windows Machines, it becomes quite easy to reach a PathToLongException, when building larger projects. This can cause other side effects

Creating ZIP files using Powershell

I’ve been working with a RemoteX [http://www.remotex.se] version of the Continuous Delivery pipeline that is available at github [https://github.com/morkeleb/continuous-delivery-with-hudson]. At RemoteX we have all our deployment done using PowerShell so to maintain as much familiarity as possible between builds and deploys were

Book review: Continuous Delivery

I recently finished reading Continuous Delivery [http://continuousdelivery.com/] by Jez Humble and David Farley. I have to say that the book was quite exiting. The first parts showed how to implement a continuous delivery pipeline and where automated tests fit in. It also explained how to setup the automated

Deploying updates for RemoteX Applications using Hudson

We’ve been doing some work with Hudson over the past weeks. Mainly We’ve managed to create the last part of RemoteX [http://www.remotex.se] delivery pipeline on a hudson build-server. Since the first release of RemoteX Applications we’ve been releasing each release as a “package” containing

Doing Continuous Delivery with Hudson and Git

Right now I’m reading the book Continuous Delivery [http://continuousdelivery.com/]. Excellent reading and even though I’ve only read around 46% percent of it, it’s quite thought provoking. I’ve written earlier on how we at RemoteX [http://www.remotex.se] have set up our build environment

Version 0.2 of the Remotestick webgui

I just finished “version 0.2” of the Remotestick [http://www.remotestick.org/] webgui I’ve been working on. I also created a webpage on this site [https://www.morkeleb.com/software-portfolio/remotestick-webgui/] describing what you can do with the interface.
