Re: about TDD (Test Driven Development)
TDD isn't a Technic its a mindset or a philosophy.
It came from the Agile manifesto http://agilemanifesto.org/ <http://agilemanifesto.org/> .
So if you can test something in a language (if its build in or not) you can run do TDD.
Often young developers don't see the need for writing test and even experienced hackers don't do.
How often where you hunting a bug and you had to log stuff to hunt the bug?
Or how often you see code and you go WTF?
Here come test in handy. Now the young padawan may ask why?
IF a test is good written you don't need to log stuff because when you break something the test will tell you what and where.
Now the young padawan says: But should't I write good code instead?
Yes, but the god like programmer is a Myth and if you think your a good hacker your probably a very bad one! << Facts !
But how test can make me faster understand someones code?
Simple: People how have Higher Mathematics in School/College/University probably have seen mathematical proofs.
Most students think that Teachers do that to annoy the shit out of you but this is just wrong and you probably very bad at Mathematics too...
In Mathematical proofs like in test we can see the essence of what the hacker wanted to do.
By looking at what he tested and how we can understand how things works and how the shouldn't.
SO you can not test and the code must be rewritten a lot like in contractor. maybe not today or maybe not in 1 or 2 months but at some point it will happen and if the guy how wrote the shitty code is not there anymore you will prey for test and a documentation of the code.
OH and when people say: look at the source and you will understand it. they are pretty dumb too...
Hacking is Art! If I look at the Mona Lisa and someone else will do we maybe see the same thing but think very different!
So don't be dumb! Test and Document if you have the workflow right it will take not more then 10 minutes of a work hour but it will save letter tons and tons of work hours!

Betreff: [Elementary-dev-community] about TDD (Test Driven Development)
I read some threads focusing on TDD, so I wanted to create one where we can continue that conversation without being offtopic.
I'd say my two cent about TDD and elementary os development.
In my opinion our current environment is obstile to TDD for serveral reason:
1. Vala doesn't support TDD out of the box ( other languages do: http://cobra-language.com/ <http://cobra-language.com/> )
2. GLib.Test is a unit test facility that is available to Vala applications, however it's not as advanced as CppUnit, NUnit and equivalent
3. TDD is great for libraries and backends, not so much for GUI applications and Database driven applications.
4. TDD needs lots of fakes and mocks to be written, and that could be very time expensive ( and tedious sometimes )
Some references to Unit testing on vala apps:
