The purpose of testing is not to prove anything -- it about detecting defects.
The purpose of unit testing is to prove that there are no defects and program/library/class works as expected.
Really? Can you *prove* that a software has no defects? There's no such thing as a bug free software.
Obviously we can't prove-prove anything. But testing the other best thing we can do. It should give us assurance (or in other words be good enough proof) that software works as expected. Meditations like "it's obvious it can work" is no comparison. In software business it's more like "guilty until proven innocent". Gennadiy
