I failed to get my hands on the actual research paper so I'm relying completely on the article's description of the study. To my unscientific eye it seems that the only thing altered between the control group and the test group was diet. Both were given "Compound 14". The test group that was fed a high fat diet showed better results. Claiming that it's thanks to "Compound 14" seems a little bit unscientific. What I would like to know is: 1) What did the normal diet look like? 2) What would the results be like if both the control and the test group were fed the exact same diet from birth? 3) What are the researchers' biases? 4) Who is funding the research?

My team was in the same situation as you about 2 years ago. We started writing tests for bugs that were reported by customers, as those were the "hot-spots" for regression. As we became more confident and adept at using JUnit, we started writing tests for new features too. Only after 6 months did we start looking at places in the code that were not covered by unit tests and started filling them in to avoid regression. It was a lengthy process to get our coverage to a decent level, but it was definitely worth the struggle.
