Completely agree. The author is trying to blame tests for code complexity. GetSolarTimes() is a simple function evaluating an equation - treat it as such. If your code is broken down clearly into logic and plumbing, unit testing the logic becomes super easy. It allows you to construct software using blocks you have absolute confidence in. Unit testing plumbing is harder, and that's when integration testing shines.
