Quick Oracle: Blink Testing

Sunday, July 17th, 2005

Background:

In testing, an “oracle” is a principle or mechanism by which we recognize a problem. This contrasts with “coverage”, which has to do with getting a problem to occur. All tests cover a product in some way. All tests must include an oracle of some kind or else you would call it a tour rather […]

I want to stamp out “best practice” for several reasons:
