I'm on my iPhone and so the material is a little hard to read, but from my eye the chart separates all texting into four segments and has just one for formal code testing. The thesis tends to rely on this graph to make its point. It seems to me this is incorrect; rather, code review beats the best single method of testing. In aggregate testing is hard to beat. Like another poster said, this was just linkbait. Would rather see a more reasoned analysis.
