Productoriented testability requirements are proposed to improve the ability of detecting and isolating defect, in which would affect the ease of detecting and isolating defects during testing. The reviewed productoriented testability requirements will be treated as a part of the offering requirements of the product under construction. 2. Softwareoriented testability requirements are proposed to ease the test development and execution when verifying the software of a product.3. Hardwareoriented testability requirements are proposed to ease the test development and execution when verifying the hardware of a product.4. Productionoriented testability requirements are proposed to ease the testing and improve efficiency during the production of a product. Please refer to concept phase productability requirement guideline for productionoriented testability requirements. The testability requirement baselines for all products are released in our pany(part of the engineering feature requirement baseline). The baselined requirements are summarized from the long term past project experience in our pany, and it39。 初步考慮產(chǎn)品如何進(jìn)行這些測試，要說明如下問題：哪些測試是手動測試、哪些是自動測試？測試數(shù)據(jù)源是內(nèi)置在系統(tǒng)中，還是外部提供？測試數(shù)據(jù)的采集和處理是內(nèi)置，還是外置？測試數(shù)據(jù)采集裝置的控制是內(nèi)置，還是外置？測試數(shù)據(jù)源的控制是內(nèi)置，還是外置？測試數(shù)據(jù)的處理是內(nèi)置，還是外置？Summarize what tests are to be conducted. This can be summarized from testing requirements. Describe in general how these testing are conducted, the following should be explained:What are manual testing and what are automated testing?Is testing data source embedded in the system or provided from outside?Is the collection and processing of testing data achieved from inside or outside?Is the control of testing data collection device achieved from inside or outside?Is the control of testing data source achieved from inside or outside?Is the processing of testing data achieved from inside or outside?產(chǎn)品測試各階段的可測試性需求根據(jù)測試需求和策略（如具有內(nèi)置要求的測試），通過對具體產(chǎn)品特點(diǎn)的分析、內(nèi)部訪談、參考公司內(nèi)部經(jīng)驗案例并分析調(diào)研業(yè)界同類產(chǎn)品，提出可測試性需求。（2）提供信號和數(shù)據(jù)流的自環(huán)和自給設(shè)計（3）提供模塊和部件的離線加載功能 （4）提供模塊和部件的自測試設(shè)計（5）提供測試儀器和工具的測試接口或兼容性設(shè)計 。例如：產(chǎn)品設(shè)計了一塊業(yè)務(wù)板，但需要時鐘板提供時鐘才能正常工作，而提供時鐘的單板也要調(diào)試，無法支持本單板的調(diào)試，這樣為了調(diào)試這塊單板就需要考慮時鐘源的設(shè)計，可能我們需要在板內(nèi)提供一個晶振，或者利用鎖相環(huán)的壓控晶振分壓設(shè)置提供時鐘，以支持單板的獨(dú)立調(diào)試。The focus here is whether easy debugging amp。 testing equipment interface is available, which makes it easy to verify and locate where the problem es from, and support the independent debugging amp。 output data sources necessary for independent debugging amp。 testing experience, new requirements brought about by using new ponents and development technology, requirements brought about by new method, requirements brought about by raising development efficiency.、軟件模塊的調(diào)試和測試中的可測性需求Testability requirements of software module debugging and testing關(guān)注點(diǎn)主要在于按設(shè)置測試控制序列、狀態(tài)觀測點(diǎn)和輸入輸出機(jī)制的需求，主要考慮以下幾個方面的內(nèi)容：（1）提供軟件模塊調(diào)試測試的能控性設(shè)計，能通過輸入設(shè)定的測試序列使系統(tǒng)處于某種特定的狀態(tài)或滿足某種特定條件的狀態(tài)。（2）提供軟件模塊調(diào)試測試的能觀性設(shè)計，能夠通過系統(tǒng)的輸出數(shù)據(jù)判定系統(tǒng)是否處于某種特定的狀態(tài)或滿足某種特定條件的狀態(tài)。(3)軟件可測試性需求分為內(nèi)建、公共、產(chǎn)品特性等三類，內(nèi)建測試能力與公共可測試性需求合入產(chǎn)品包需求，在確定設(shè)計需求時，對具體產(chǎn)品特性需求分析的基礎(chǔ)上，提出相應(yīng)的特性可測試性需求。針對產(chǎn)品具體特性測試的方便性提出的需求，它們與特性緊密相關(guān)，以特性樹的方式組織公共可測試性需求，例如：OS中內(nèi)存管理這些更具有公共性的部分。也是以特性樹的方式組織。它是最具有公用性的部分。它描述了產(chǎn)品應(yīng)該具有的支持測試能力的需求。這些需求的被實現(xiàn)，可以有力的支持前兩類需求的實現(xiàn)。它們都需要調(diào)用這里提供的機(jī)制來真正的完成跟蹤。
