There seems to be so much emphasis on testing in the Rails community.
This is just food for thought…
Kreitzberg and Shneiderman
* Testing by itself does not improve software quality. Test results
are an indicator of quality, but in and of themselves, they donâ€™t
improve it. Trying to improve software quality by increasing the amount
of testing is like trying to lose weight by weighing yourself more
often. What you eat before you step onto the scale determines how much
you will weigh, and the software development techniques you use
determine how many errors testing will find. If you want to lose weight,
donâ€™t buy a new scale; change your diet. If you want to improve your
software, donâ€™t test more; develop better.
