At the Adobe MAX 2009, it was interesting to improve my knowledge in the Test-Driven Development (TDD) and see the new features of Flash Builder 4 in action.
The Unit Test Agents of Flash Builder 4 are simplifying most of the work for you. They can be extended to higher levels just like the old FlexUnit would do, but on top everything now is included in the SDK, well integrated and well documented. TDD is very important for us when working on major or critical applications, since it allows us to reduce errors and bugs. Even though you might increase development time in the beginning by finding errors, incomplete or even missing functionalities, you will end up with less problems to solve gain the time that would be spent debugging the app.
TDD is a great way to deliver with agility an almost bug-free solution in this very competitive business environment.
