Software development company, HSBC and Information Technology Center (certified), software development provided by the Shenyang City HSBC and IT center. Shenyang abundance and Information Technology Center (www.4000010001.com) is specialized in the "software development, website design, development of micro-channel public number, 400 calls for the network to promote the" enterprise, the company of "honesty, hard service" concept provide you with the highest quality products and services. Welcome to inquire! Contact: Li Enze. 5 The purpose of the test is based on software testing smaller price discovery as many errors. The key to achieving this goal is to design a good test case (test data and functions and expected outputs form the test case). How to design a good test case, the key is to understand the testing methods. There are different test case design different test methods. Two commonly used test is the test object is a white box method source code, based on the logic of the internal structure of the program to find software programming error, structural errors and data errors. Structure errors include logic, data flow, initialization error. The key use cases are designed with fewer cases to cover as much of the internal program logic results. White-box and black-box method method is based on the functional behavior of the software, or software described in Beijing software development company, discovered interfaces, functions and structure of software errors. Interface errors which include internal / external interface, resource management, integration, and system errors. Key black-box method is also designed for use cases with less use cases covering module outputs and inputs. For example look at: a man looking for a company to build a personnel management software Android software development tutorials, from some sources that we have to provide this service Apple software development, so in touch with us. We will send two specialized software engineers to them to understand what we want to design a thing to them to use, then come back and make a plan to them, including the contents of the program include: We developed a software interface that is probably what? What people easy to use? Who can use what function? Convenient to what extent? What about hardware requirements, etc.?
