【文章內(nèi)容簡介】 ebugging amp。 testing, which can make the system ing into or satisfying some special states.(2)The observation of software module debugging amp。 testing, usually the observation points and observation equipment are considered here, through which the system state can be visible by the output message, and we can know whether the system is under the certain state we need. （3）Software testability requirements are classified into three type, and they are product featureoriented testability requirements, buildin test capability and mon testability requirements. buildin test capability and mon testability requirments will be add into IPD end to end offering requirement, and during analysis of product design requirements, product featureoriented testability requirements will be analyzed based on analysis of product feature requirements.featureoriented testability requirements, which are proposed according to the actual features of a product. Such requirements are strongly relative to the feature of a products, and they are organized by different features.mon testability requires. such as memory management functions in a OS, they are mon to the public and not featureoriented to a particular product, they are called the mon testability requirements. such requirements could be organized by a featuretree as well, such as memory management feature, queue feature, and etc.buildintest capability requirements. they are the most mon part of a testing facility, and be called buildintest capability requirements. such requirements depicted the product under construction should support a certain kind of testing capability. for example, if we implement a tracking facility, it could well support the tracking and interfacing requirements from the above two kind of testability requirements. as the figure shown below are the infrastructure of the buildintest facilities:本部分需求主要來源于測試策略、經(jīng)驗總結(jié)以及內(nèi)部訪談和調(diào)研分析。 軟件可測試性需求的分析詳細過程與方法，參見測試部相關(guān)支撐流程。Requirements here usually e from test strategy ,experience, interview. from Ramp。D test dept., you can get detailed supporting process and technical guide for software testability requirements. 、系統(tǒng)聯(lián)調(diào)中的可測性需求需求的關(guān)注點主要是能夠提供一些手段，這些手段是可以暴露問題、發(fā)現(xiàn)問題、定位問題產(chǎn)生原因，解決問題、以及驗證解決效果的測試手段，主要考慮以下幾個方面的內(nèi)容：（1）測試數(shù)據(jù)源設(shè)計（2）業(yè)務(wù)和控制數(shù)據(jù)流的監(jiān)控和變更設(shè)計（3）子系統(tǒng)和模塊的故障分段環(huán)回及定位設(shè)計（4）子系統(tǒng)和模塊的自測試設(shè)計（5）測試儀器和工具的測試接口或兼容性設(shè)計（6）測試結(jié)果的記錄、分析和結(jié)果上報設(shè)計例如：系統(tǒng)聯(lián)調(diào)中如何區(qū)分不同單板、不同模塊之間的故障，出了故障后問題是出在這個單板/模塊還是出在與之接口的那個單板/模塊，是我們經(jīng)常遇到的一個問題。需要考慮相應設(shè)計支持問題的分段/分層定位。Testability requirements of joint system debuggingThe focus here is to provide some means, which can help us to learn about and find out the problems, find the reason of the problem, as well as solving methods and effectiveness of the problems. The following contents should be taken into consideration:(1)The design of testing data source .(2)The design for inspection and modification of system business flow and control data flow.(3)Segment loop and diagnose design for subsystems and modules.(4)The selftest design for subsystems and modules. (5)The design of interface or patibility design necessary for testing equipment and tools.(6)The recording, analyzing and reporting of testing result.本部分需求主要來源于聯(lián)調(diào)經(jīng)驗、聯(lián)調(diào)測試策略以及內(nèi)部訪談和調(diào)研分析。Requirements here usually e from joint debugging experience and strategy, 、系統(tǒng)驗證測試中的可測性需求系統(tǒng)驗證測試是驗證產(chǎn)品各種指標性能是否達到設(shè)計要求，在不同環(huán)境下的指標容限如何，包括指標/接口層測試、功能/性能層測試、子系統(tǒng)/模塊層測試、應用層測試、用戶層測試，其關(guān)注點主要在于系統(tǒng)驗證測試各種測試項目能否實現(xiàn)、實現(xiàn)是否方便、出現(xiàn)問題是否可以定位。 主要考慮以下幾個方面的內(nèi)容：（1）系統(tǒng)業(yè)務(wù)功能測試的可實現(xiàn)性和方便性（2）性能指標測試與瓶頸定位的可實現(xiàn)性和方便性（3）系統(tǒng)告警功能驗證測試的可實現(xiàn)性和方便性（4）系統(tǒng)容限/容錯/極限性能測試的可實現(xiàn)性和方便性（5）協(xié)議跟蹤與驗證測試的可實現(xiàn)性和方便性。 例如：針對系統(tǒng)驗證測試中測試工作量比較大、重復次數(shù)較多的問題，往往需要考慮對自動測試的支持，提供自動統(tǒng)計功能或者相應的函數(shù)接口，便于自動測試設(shè)計和執(zhí)行。對于異常容錯測試往往需要考慮相應的硬件接口或函數(shù)接口支持。有時候接口指標測試時需要考慮測試儀器輔助信號的設(shè)計，提供測試儀器所需要的時鐘等信號接口供測試儀器使用。Testability Requirements for SVT System verification test is used for verif
