章节摘录

　　The second phase is design. Design concentrates on how the system will accomplish the goals. It is here that the structure of the software system is established. The input to this phase is a（debugged and validated）requirements document：the output is a design expressed in some appropriate form（for example，pseudo-code）.Validation of a design is important. Each requirement in the requirements document must have a corresponding design fragment to meet it. Formal verification，while possible to a limited extent，can be exceedingly difficult. More informal rev　　lve the entire design team，management，and even the client.　　It is a well-established principle that the best structure for a large software system is a modular one. Indeed，it is by means of this modular decomposition that the implementation of large systems becomes a possibility. Without such a breakdown，the technical details required in the implementation of a large system would exceed a human’s comprehensive powers. With a modular design，how eve Lonly the details pertaining to the module under consideration need be mastered. This same modular design is also conductive to furore maintenance because it allows changes to be made on a modular basis.　　The third phase，implementation，is the actual coding of the design developed in the second phase. The design must be translated into a machine-readable form. The coding step performs this task. If design is performed in a detailed manner, coding can be accomplished mechanistically. The lure of this phase is strong，and many a fool hardy programmer has been drawn to it before adequately laying the groundwork in the first two phases. As a result，requirements are incompletely understood and the design is flawed. The implementation proceeds blindly, and many problems arise as a result.　　The forth phase is software testing. Testing is closely associated with implementation，because each module of the system is normally tested as it is implemented. In the development of a large system, testing involves several stages. First，each program module is tested as a single program，usua　　ly isolated from the other programs in the system. Such testing is defined as module testing or unit testing. Unit testing is done in a controlled environment whenever possible so that the test team Call feed a predetermined set of data to the module being tested and observe what output data are produced. H In addition，the test team checks the internal data structures，the logic，and the boundary conditions for the in put and out put data.　　When collections of modules have been unit-tested. the next step is to insure that the interfaces among the modules are defined and handled properly. Integration testing is the process of verifying that the components of a system work together as described in the program design and system design specifications. Once we are sure that information is passed among modules according to the design prescriptions，we test the system to assure that it has the desired functionality. A function test evaluates the system to determine if the functions described by the requirements specification are actually performed by the integrated system.　　Unfortunately, the testing and debugging of a system is extremely difficult to perform successfully. Experience has shown that large software systems can contain numerous errors. Even after significant testing. Many of these errors may go undetected for the life of the system，but others may cause major malfunctions. The elimination of such errors is one of the goals of software engineering.
