Line 1: {{Short description\|Extent to which software can be tested}} {{more footnotes\|date=September 2014}} '''Software testability''' is the degree to which a software artifact (i.e.g. a software system, ~~software~~ module, ~~requirements-~~requirement, or design document) supports [[Software testing\|testing]] in a given test context. If the testability of ~~the software~~an artifact is high, then finding faults in the system (if ~~it has~~ any) by means of testing is easier. Formally, some systems are testable, and some are not. This classification can be achieved by noticing that, to be testable, for a functionality of the system under test "S", which takes input "I", a computable [[functional predicate]] "V" must exists such that <math>V(S,I)</math> is true when S, given input I, produce a valid output, false otherwise. This function "V" is known as the verification function for the system with input I.
