Comments on: Unit Testing Flex – What’s stopping you? http://www.compactcode.com/2009/08/unit-testing-and-flex-whats-stopping-you/ keeping software simple Wed, 18 Aug 2010 04:20:00 +0000 http://wordpress.org/?v=2.9 hourly 1 By: Javier http://www.compactcode.com/2009/08/unit-testing-and-flex-whats-stopping-you/comment-page-1/#comment-183 Javier Thu, 05 Nov 2009 00:47:31 +0000 http://www.compactcode.com/?p=48#comment-183 I think the point of Unit testing is missed by some of the comments here. Unit testing is not about finding bugs in the code like this article says: http://blog.codeville.net/2009/08/24/writing-great-unit-tests-best-and-worst-practises/. It's actually a "tool", a blue-print if you like, of what your code should do...that is why unit test are written before any code is created...it's like our professors always said: before you write any code, put it down on paper" -> same idea, different method.

And FlexUnit 4 is a great tool. However, to apply it to Cairngorm architecture, which is mandatory in our shop, is a challenge. There is very little on this topic. If you can help to any degree in this direction, I'd really appreciate it. I’m 100% for unit testing. And FlexUnit 4 is a great tool.

I won't argue with you that there is a cost associated with unit testing. However I will say that regardless of how perfect your code is you will always have to test it before you release it. I used to spend a lot of time manually testing my code, now I spend that time writing automated tests. If you don't see unit testing ever becoming part of your day to day development there is nothing wrong with that. However I challenge you the next time you discover a bug in your production code to see if you can write a unit test that identifies it :) @Darren

Having read some of your examples now, it doesn't seem like it's worth the cost in development time for GUI components, or, in most cases, Flex in general. Flex is by definition a client-side technology. You should never, ever trust the client so before anything is committed to the database on the server-side it should be strcitly validated and checked for errors (unit testing makes sense here). Should you compromise on code-quality (for GUIs)? Yes, I think it's acceptable if it means development time will be much less. Just get good at programming and there shouldn't be many bugs to start with. Structure your code well and the bugs that are found will be easy to isolate and fix. Think of it like this. You're a journalist for the NY Times. All your work is checked by two editors. Once every couple of months a typo or two makes it through. Does this mean that all your work should now be checked by four editors? I don't think so... Surely, unit-testing is a development time/code quality tradeoff.
