【正文】 sts may be run with the system on board each type of ship that will eventually use the system. Build or lnteration Plan. Ideally,after program testing,you can view the collection of ponents as a single ,during the first steps of system testing,the integrated collection is evaluated from a variety of perspectives,as previously ,large systems are sometimes unwieldy when tested as one enormous collection of fact,such systems are often candidates for phased development,simply because they are much easier to build and test in smaller ,you may choose to perform phased system saw in Chapter 1 that a system can be viewed as a nested set of levels or level is responsible for performing at least the functions of those subsystems it ,we can divide the system into a nested sequence of subsystems and perform the system test on one subsystem at a time. 漢語翻譯： 文檔對象模型和動態(tài) HTML 術(shù)語中的動態(tài) HTML，通常簡寫為 DHTML,通過客戶端腳本引用制作動態(tài)網(wǎng)頁的技術(shù) 來操作文件內(nèi)容和文件描述。faults detected early are easier and cheaper to ,plete and early testing can helo not only to detect faults quickly,but also to isolate the causes more early. shows the reasons for faults,not evidence of testing aims to uncover as many faults as possible,it is concerned with where they may how faults are created gives us clues about where to look when testing a system. System Testing Process There are several steps in testing a system: testing testing testing testing The steps are illustrated in Figure step has a different focus,and a step’s success depends on its goal or ,it is helpful to review the purpose of each step of system testing. Process Objective. Initially,we test the functions performed by the begin with a set of ponents that were tested individually and then function test checks that the integrated system performs its functions as specified in the example,a function test of a bank account package verifies that the package can correctly credit a deposit,enter a withdrawal,calculate interest,print the balance,and so on. Once the test team is convinced that the functions work as specified,the performance test pares the integrated ponents with the nonfunctional system security,accuracy,speed,and reliability,constrain the way in which the system functions are instance,a performance test of the bank account package evaluates the speed with which calculations are made,the precision fo the putation,the security precautions required,and the response time to user inquiry. At this point,the system operates the way the designers call this a verified system。 河北建筑工程學(xué)院 畢業(yè)設(shè)計（論文）外文資料翻譯 系別： 計算機系 專業(yè)： 計算機科學(xué)與技術(shù) 班級： 計 092 班 姓名： 孫全華 學(xué)號： 2020309216 外文出處： 導(dǎo)師提供 指導(dǎo)
