I tend to agree that TDD is a bit excessive, but I strongly believe in a BDD approach which is very common in Domain-Driven Design. Writing the failing test cases that describe how what use cases, policies and rules a system should have is much more likely to be known at the start of a project than if "computeXYCoordinates()" returns false :)
Writing code is a mixture of both!
It's science!
Computer "SCIENCE" is theory. The way that mathematics, physics and information work together to "determine how many users this application will be able support under peak hours" is a bit of physics, math, and probability all in one!
A very common feature in science is that it's very hard (and sometimes impossible) to prove that something is correct, so we often deem things correct enough if we can't prove it to be false.
That's unit testing :)
Computer "programming/coding" is the practical application of such theory. It's also what leans more in the direction of....
Art!
There are 100s of ways of writing code to perform the same observable behaviour. It takes skill, practice, patience and empathy to create code that is timeless, well-designed and readable for future developers.

We're a place where coders share, stay up-to-date and grow their careers.
