Lecture1 - A Bug or Not a Bug -> Quick Intro -> Three Conditions Of A Bug’s Existence -> The Gist Of Testing -> Spec, Spec, Spec -> Software Bugs And Spec Bugs

The main sources of expected results are:

            1. Specification

            2. Specification

            3. Specification

            4. Life experience, common sense, communication, standards, statistics, valuable opinions, etc.

Specification being stated three times in a row is not a problem with my keyboard, but my way of stressing that specification is:

– the most important

– the most valuable

– the most respected

source of expected results within your software company. Specification is as important for a tester as a script is for an actor or traffic laws for a driver. So, what is specification?

Specification (or “spec” for short) is a detailed description of how software should work and/or look.

Please note that some startups just don’t have specs – in a minute we’ll discuss what to do in that case.
