29、 expected to pro-vide material for use in a quality assuranceprogram. This standard does not recommend aparticular approach toward quality assurance.Questions about frequency of reviews or au-dits, resolution of discrepancies, or responsibil-ity for configuration control are not within thescope of t

30、his standard.2 DefinitionsIn the context of this standard, the followingdefinitions apply.non-safety-related: Software whose failurewould not create a hazard to a facility, worker,or member of the general public.validation: a! The process of testing a com-puter program and evaluating the results toe

31、nsure compliance with specified require-ments. b! The demonstration that the verifiedcomputer programand by inference the math-ematical model! are an adequate representa-tion of the physical phenomena.verification: The process of evaluating theproducts of a software development activity toprovide as

33、age;test plan;VV the design specification isverified against the requirements specifica-tion; and the source code is examined to ensureconsistency with the design specification.The criteria presented in this document de-pend upon the availability of a document stat-ing the requirements that a comput

34、er programmust satisfy. Because of the research basis ofmost scientific program development, how-ever, it is often not possible to provide a prioria complete requirements specification. Whatconstitutes a valid answer or appropriate algo-rithm is often not known until after differentapproaches have b

35、een tried and their resultsevaluated. In such cases an iterative approachis recommended that allows the requirementsto be refined or respecified as results fromdifferent activities of program development be-come available.

45、 infor-mation becomes available.5.4 Verification of preliminary testplansTest plans prepared during program definitiondescribe the tests to be used to validate thesoftware product. A preliminary test plan de-fines the scope, objectives, and testing ap-proach; provides an initial description of thete

46、st problems, test cases, and test proceduresthat will be used; and describes the plannedreporting formats and procedures.Verification of a preliminary test plan is per-formed to ensure the following:1! The testing approach is consistent withthe scope and objectives stated in the plan;2! The tests be

47、ing considered will be ade-quate and sufficient for demonstrating thatthe program conforms with the requirementsspecification;3! The reporting formats and procedures areconsistent with the Vdetailed descriptions of each test case, in-cluding, as applicableH18537 identification of any programs that w

The tests being considered will be ade-quate and sufficient for demonstrating theprogram conforms with the requirementsspecification;2! The updated test plan is consistent withthe design specification and the preliminaryprogram documentation.Verification of a test plan is given in Checklist2 in Appendix A.
