ATDD / BDD

TDD:

ATDD

BDD : is an approach to build software.  
Talk first,, Act later..

A common problem with poor unit tests is they rely too much on how the tested function is implemented. This means if you update the function, even without changing the inputs and outputs, you must also update the test. This is a problem because it makes doing changes tedious.

so instead of thinking of how the code is implemented, we spend a moment thinking of what the scenario is. Typically you phrase BDD tests in the form of “it should do something”. So when ticking a counter, it should increment count by one.

Unit Testing gives you the what. Test-Driven Development gives you the when. Behavior Driven-Development gives you the how. Although you can use each individually,
