Most scientists are not software engineers so would not know about comprehensive testing. This was an eye opener to me when I moved from academia to a scientific software company. The situation is improving somewhat as many grad students open source their software in github. Then have include their makefiles, documentation, and some tests. In earlier days we we software engineers would roll our eyes when management suggested using 'free' university code to save money. Sometime bringing such software up to professional industry standards took more work than starting from scratch from published papers.
