TDD requires you to draw your target first, then hit or miss it with the code, like in science: hypotheses -> confirmation/declining via experiments -> working theory.

But in practice, lot of coders are hitting a point instead, then they draw target around that point, like in fake science: we throw coin 100 times, distribution is 60/40, our hypothesis: random coin flip has 60 to 40 ratio, our hypothesis confirmed by experiment, huge savings, hooray!
