Overview¶
Test Driven Development (TDD) is a method of designing software.
It goes roughly as follows: write UnitTests for the code before you write the code itself.
Why do it the “non-natural” way, then? Well, there are some benefits and very few - if any - drawbacks:
Coding tests means you have to call your non-existing code with all the parameters thus forcing you to think how your library should work, thus it fixes the Signature of your code
You realize many errors in the code before you even wrote it, especially design-related errors
You will get better estimate how long coding will take
It is very important to emphasize TDD is not a testing methodology; it is a design methodology.
