Basic Unit Testing Guidelines

When I recently started looking through a certain project’s tests, I was struck by how difficult it was for me to read and understand. The tests were laid out haphazardly, and the code contained enough logic to make me wonder if it would be easier to analyze the functional code. Tests don’t do anyone good if they require that much analysis. In contrast, one of my favorite open source projects contains tests that allow me to learn the functionality of the system without looking at any functional code.
