While talking to one of the client stakeholder, I came across this interesting term as Test-Along Development.
Following are two different techniques I came across as common way of writing unit test:
Both of the above techniques presented enough challenges to the software developers. Some of them are following:
So, What is Test-Along Development (TAD)?
Simply speaking, TAD is writing unit tests as you are developing the code. This technique is simpler than TDD. However, this is still challenging. Developers still have to plan about unit tests much earlier and, for that reason, have to understand the requirements more diligently.

Are you saying that in TDD *all* unit tests should be written before the code? My understanding of TDD (and the "version" that I practice) is what you're calling TAD. I would never attempt to write a full suite of tests in advance of any code, unless the suite was expressed entirely in pseudo-code.
