Open Source: Behavioral Driven Development Testing Framework

  •  
  •  
  •  
  •  
  •  

For those unfamiliar with the term behavioral driven development testing (BDD) frameworks are used so that you can test applications using logical English like syntax.

I have come across an open source  framework designed specifically for iOS devices.   What’s cool about this specific framework is that it can easily be attached to Objective-C methods, runs in the simulator, and let’s you store your different stories in different files so you could easily demonstrate your software’s ability to cope with different scenario’s.

Here’s an example of the types of a story used for testing:

Story: Example story showing the basic syntax.
Given Simon is working
Then I should be able to see abc and 5 in the log and say goodby at the end.

The framework is known as Simon, and was created by Derek Clarkson.

It can be found on Github here:
https://github.com/drekka/Simon

UPDATE: Got feedback about another framework known as Kiwi you may want to check out if this interests you.

I had never used one of these frameworks before, but it looks like a great way to illustrate an app does exactly what it should do. HKSAB58YGFWN

Tool: Objective-C Code Generator For Faster App Development

Found a very interesting tool that I have been using today that is absolutely brilliant for anyone programming in Objective-C on iOS and Mac.  The tool is known as Accesorizer.

What this tool does is allow you to generate repetitive Objective-C code using fully customizable parameters.  It’s tough to explain exactly what this tool does as it is completely different from anything I have used before, and it will take awhile for me to exploit the power of this tool.

If I did have to explain it though, I would call it super code complete on steroids.

Looking through the quick start guide should give you a very good idea about the coolness of this tool.

This video from the creator might make things a bit clearer (sorry it’s a download – previous Youtube video was removed):
Accessorizer Demo Video

You can find a trial version on the Accessorizer homepage which lasts for 30 days.

A great timesaving tool for sure.

Open Source: Restkit Library For Easier Communication With RESTful Web Services

  •  
  •  
  •  
  •  
  •  

Communicating web services can be a pain on iOS.  Some of the Cocoa classes for web communication are not available which doesn’t help.  Fortunately there are a number of open source projects that have made things easier for communicating with web services in Objective-C.

One such project is Restkit, and what Restkit provides is a very high level framework for communicating with RESTful services.  Restkit works on the iOS and Mac OS X platforms.  What really makes Restkit different from the similar projects out there is simpler usage syntax, and direct integration with Core Data so you can easily persist remotely loaded objects locally.

There are some great examples on Git included with Restkit demonstrating usage with a message board built in Ruby on Rails, an example of how to communicate with Twitter, and a step by step tutorial demonstrating commonly used functionality.

You can find the homepage of Restkit here:
Restkit

The Github project can be found here:
https://github.com/RestKit/RestKit

Looks like a great framework for those looking to integrate Restful web services into their apps as quickly as possible.
