Better than Google: Real answers for Programmers, System Administrators and IT Professionals
June 7, 2009 | Comments Off
Technology is more complex now than ever. It seems like the diversity of topics a programmer, system administrator or IT professional must have some familiarity with grows exponentially. In the office it is all to common to hear someone say “Did you google it?” or “I found a post that looks like it might be related on google.” when trying to sort out complex technology issues.
Google is good, but real people working together, sharing their experience with each other and documenting the results for others to take advantage of works even better. Two sites that should be in every technologists bookmark list are stackoverflow and serverfault.
You can think of these sites as social networking communities with very focused areas of interest. Anyone can post a question to a site, anyone can provide an answer, and everyone votes on the best answers. Comments can be added to questions or answers, folks develop “street cred” by providing useful answers and eventually become recognized by their peers as knowledgeable on specific topics.
Stack Overflow is a collaboratively edited question and answer site for
programmers – regardless of platform or language. It’s 100% free, no
registration required.
Server Fault is a collaboratively edited question and answer site for system
administrators and IT professionals – regardless of platform. It’s 100% free,
no registration required.
Setting up Unit Testing in Xcode 3.1
July 28, 2008 | 2 Comments
Xcode includes OCUnit, so you don’t need to get a copy. But, you might want to take a look at their website (http://sente.epfl.ch/software/ocunit/) for information and tutorials on how OCUnit is intended to be used.
If you are planning on doing Test Driven Development (TDD) you may also want to get the following packages:
- OCMock – OCMock is an Objective-C implementation of mock objects. (http://www.mulle-kybernetik.com/software/OCMock/)
- Hamcrest – library of matchers for building test expressions (http://code.google.com/p/hamcrest/)
Other good articles on Xcode Unit Testing that I came across:
- Unit Testing with OCUnit – http://www.macdevcenter.com/pub/a/mac/2004/04/23/ocunit.html?page=1
- Test Driving Your Code with OCUnit – http://developer.apple.com/tools/unittest.html
- Xcode unit testing articles – http://chanson.livejournal.com/tag/unit+testing
- Unit Testing with Xcode – http://www.stiefels.net/2007/05/01/unit-testing-with-xcode/
By reading through the documents references above I was able to get OCUnit up and running for one of my projects. It took a bit of experimentation, but in the end it looks like OCUnit will work just fine for doing TDD in Xcode with Objective-C. Anyone wanting to try out TDD should give it a try. The benefits for your project are significant. Go for it!
